Here’s how you can disable search engine suggestions on Safari:

• Launch Safari, click Safari in the menu bar and select Settings from the drop-down menu.
• In the Settings window, click the Search tab.
• Uncheck the box next to Include search engine suggestions to disable the feature.

• Close the Settings window and test Safari by typing into the search bar to see if there is an improvement in responsiveness.

8. Disable Autofill

Autofill automatically completes forms using stored information, which, while convenient, can sometimes cause Safari to lag, especially if there’s a lot of data stored. Disabling this feature can help Safari run more smoothly.

Here’s how you can disable Autofill on Safari:

• In the Settings window, click the Autofill tab.
• You will see several options for different types of information that Safari can autofill. Uncheck the boxes next to the types of information you don’t want Safari to autofill.

• After making the changes, close the window and restart Safari to apply the adjustments.
• With Autofill disabled, navigate to various websites with forms and assess whether there’s an improvement in Safari’s speed and responsiveness.

9. Update Safari

How to Speed up Safari on Your Mac

In this article you will find the following:

Safari is the fastest browser on the Mac, but it isn't immune from slowdowns and performance issues. If web pages take longer to load or site navigation doesn't feel responsive, read on to learn how to speed up Safari on Mac.

• How to speed up Safari on Mac

Is Safari running slow on your MacBook, iMac, or Mac mini? Connectivity issues, unoptimized extensions, cache corruption, and a host of other reasons often cause that. Try the suggestions in our guide to get Safari running smoothly on Mac again.

Before you start   If you want to speed up Safari on Mac quickly, download MacKeeper . It's an Apple-notarized maintenance utility that helps prevent browser slowdowns and other Mac-related issues.     MacKeeper lets you free up the RAM, delete unwanted Safari extensions, get rid of junk files, and more with considerably less hassle than manual maintenance. You get one fix for free, so don't hesitate to check if it works for you.

Check if your internet's slow

If webpages in Safari take too long to load or fail, it's a good idea to begin by figuring out if it's just a matter of your internet being slow. The best way to do that is to use an online speed checker like Fast.com or SpeedTest.net .

Restart your router if you find that your internet isn't uploading or downloading at a decent rate. If that doesn't speed it up, learn what else you can do to fix a slow internet connection on Mac .

Also, don't discount server-side issues. If the problem is limited to a specific site, use a website monitoring tool such as Downdetector to determine if you're dealing with a server outage.

• Close unnecessary tabs in Safari

Although Safari is adept at handling dozens of tabs, having too many open simultaneously will eventually take its toll on your Mac's memory. That creates delays while loading new pages, and the performance hit could also result in erratic browser behavior.

The quickest way to speed up Safari on Mac is to shut down unnecessary tabs as soon as you notice any slowdowns. Getting used to moving between and closing tabs using the Ctrl + Tab and Command + W keyboard shortcuts can make the process even faster.

• Shut down apps and resource-intensive processes

Tabs aside, Safari will run slowly on the Mac if you have too many applications open. Check your Mac's Dock and quit anything you aren't actively using. Try force-quitting troublesome programs if you can't close them normally.

On the other hand, various apps and related processes can spin out of control and consume too much processing power and memory. Use the Activity Monitor to locate and stop them.

• Open the Launchpad and select Other > Activity Monitor
• Sort your Mac's activity using the % CPU column and shut down any third-party processes that use a significant amount of CPU
• Switch to the Memory tab and stop third-party items that use lots of RAM.

If you always end up pushing the hardware on your Mac to its limits, consider using MacKeeper's Memory Cleaner feature to keep things under control.

• Disable unnecessary Safari extensions

Running Safari with multiple extensions increases the load on the CPU and RAM. That translates to slower browser performance, so review your list of browser add-ons and disable any items you don't regularly use.

• Open Safari and select Safari > Preferences on the menu bar
• Switch to the Extensions tab
• Clear the boxes next to any extensions you want to disable.

Our team highly recommends you update Safari extensions periodically via the Mac's App Store to ensure they run in top shape. If you notice anything suspicious, learn how to remove malicious browser extensions and toolbars from your Mac.

• Switch DNS servers for Wi-Fi and Ethernet

DNS (short for Domain Name System) is a cataloging system that matches domain names with IP addresses. Not all DNS providers are fast, so changing your Wi-Fi or Ethernet's DNS settings to a popular service like Google DNS can speed up Safari on Mac. For best results, clear the DNS cache on your Mac before you begin .

• Open the Apple menu and select System Preferences
• Select the Network category
• Select Wi-Fi/Ethernet > Advanced
• Switch to the DNS tab
• Select OK > Apply to save your changes.
• Clear the Safari cache and cookies

Like most web browsers, Safari caches various forms of site data — images, HTML files, and JavaScript code — to improve load times in subsequent visits. However, a bloated or corrupt cache can adversely impact performance and result in Safari running slow on the Mac. You can clear the Safari cache after activating its hidden Develop menu .

• Switch to the Advanced tab and check the box next to Show Develop menu in menu bar
• Select Develop on the menu bar and pick the Empty Caches option.

Corrupt, outdated, or privacy-invasive browser cookies can also slow down Safari. If deleting the Safari cache didn't make much difference, try deleting its cookies next.

• Select Safari > Clear History on the menu bar
• Set Clear to All history
• Select Clear .

Update the Safari browser

Safari receives occasional bug fixes and performance enhancements from Apple, and these arrive alongside regular macOS updates .  

To update your Mac:

• Select Software Update
• Wait until the Software Update tool checks for newer macOS updates and select Update Now to install any pending updates.

Even if a new macOS update doesn't include anything Safari-related, installing it will still improve general performance across native apps. Make it a point to install macOS updates as soon as possible.

• Reset Safari to factory defaults

Corrupt browser preferences and other underlying issues can also play a factor, so sometimes, the only way to fix a slow instance of Safari on Mac is to reset it to factory defaults.

A Safari reset deactivates all extensions and reverts each browser setting to its defaults, allowing you to start over with a clean slate. You will not lose your bookmarks or passwords during the process.

• Save your work and exit Safari
• Open Finder, select Go > Go to Folder on the menu bar, and visit the ~/Library/Preferences/ directory
• Search for com.apple.Safari.plist file and delete it
• Reopen the Go to Folder box and visit ~/Library/Safari/ . Then, delete each item within the folder except the Bookmarks.plist file
• Visit ~/Library/Containers/ , search for Safari, and delete all files and folders that appear among the search results
• Open Safari and visit its Preferences pane to reactivate any essential extensions. Also, move between tabs and modify your browser settings the way you want.
• Boot your Mac into Safe Mode

If none of the fixes above help speed up Safari, try booting your Mac into and out of Safe Mode. That helps flush out various forms of temporary data that can interfere with Apple's browser.

On an Intel Mac, you can get to Safe Mode while holding down the Shift key during the reboot phase. However, if you use an Apple Silicon Mac, you should:

• Shut down your Mac
• Turn it on but keep holding the Power button until you get to the Startup Options screen
• Hold the Shift key and select Macintosh HD > Safe Mode .

In Safe Mode, repeat the fixes above if you could not complete them earlier. Then, restart your Mac normally. To delete additional forms of temporary data that can slow down Safari, learn how to delete your Mac's application and system caches .

• Full steam ahead

Keeping Safari in top shape is crucial for a great web browsing experience. Avoiding too many open tabs, shutting down unwanted apps and processes, and cutting down on the number of active extensions can go a long way toward making that happen. Occasionally clearing the Safari cache and keeping your Mac up-to-date will significantly minimize browser slowdowns and other issues. If manual Mac maintenance feels like a drag, don't forget to download MacKeeper .

Experiencing Safari slowdowns on your Mac? Whether it’s loading issues or post-Monterey update sluggishness, these common glitches can be frustrating. In this guide, we’ll explore why Safari is lagging and provide solutions for a smoother browsing experience.

Note: if Safari is not just slow, but keeps freezing and crashing, read this post instead for more troubleshooting tips.

Key Takeaways:

• Clear Cache: Overloaded cache can slow Safari. Clear history and cache through Safari settings for a speed boost.
• Extensions Check: Outdated or excessive extensions can drag Safari down. Remove unnecessary ones via Safari settings.
• Update Safari: An outdated Safari version might cause slowness. Update it through the App Store.
• Network Check: Slow Safari might be due to network issues. Test internet speed to rule this out.
• User Account Check: A corrupted user account or macOS issues can affect Safari. Test on a new user account and run disk utility checks.
• Tab Management: Too many open tabs strain Safari. Close unnecessary tabs for better performance.

Why is Safari so Slow?

Safari could be slow because you’re using an outdated version of Safari. The cache might be overworked, or you might be facing network issues. Additionally, you might have too many tabs open that are causing the app to slow down.

Important Tips

It’s normal for safari to run slow on certain websites.

By certain websites, we mean “heavy” sites that are loaded with flash or video ads on the pages you browse. Worse yet, some even auto-play without you clicking on. They tend to have your MacBook heat up quick.

The best option is to close those pages immediately when you finish reading the content on it, or you could install AdBlock Plus (Safari compatible) to block the ads from displaying.

Stop excessively multitasking

You’d be surprised how much better 90% of programs work when you don’t try and use them at the same time as a dozen other apps. It seems like a simple solution, but it is often the best one.

Take care of Safari

Some methods are a matter of habit, such as regularly clearing your cache or making sure the app is up to date. Imagine your computer as a car that needs regular maintenance to run well.

Don’t neglect the computer

Macs are not immune to viruses, despite the common perception. They also aren’t immune to file corruption or errors. Make sure you haven’t picked up anything unwanted while browsing that could be affecting Safari’s performance.

Slow Safari : 8 Possible Causes & Fixes

1. overworked cache.

The cache is a location on your Mac’s hard drive where Safari temporarily stores data that you use frequently. The cache allows Safari to reference this information quickly and therefore execute actions such as loading a specific page more quickly.

However, if the cache becomes full then Safari cannot add newer, more relevant material and is forced to use slower methods to respond to your demands.

Here’s how to erase the data in the cache so that Safari can work smarter rather than harder:

Start by erasing your history from Safari by navigating the menu bar along the top and choosing History > Clear History and Website Data .

Once you click this, you’ll be shown a small pop-up window. Choose “All History” from the bottom of the drop-down, and then Clear History .

The next thing you can do is clear the cache using a more advanced method. First, go to the Safari menu and open Preferences.

On the preferences panel, choose “Advanced” and then look for the checkbox at the bottom of the page that says “Show Develop Menu in Menu Bar”. Make sure this box is checked, then close Preferences.

You’ll notice a new tab has been added to your menu bar, called “Develop”. Click on this, and then choose “Empty Caches” from the list. You won’t be given any confirmation, but it will clear the cache and you can restart Safari and see if this has solved your problem.

2. Bad Extensions

Most people are aware that Apple doesn’t play well with Flash, but this isn’t the only plugin that could be causing Safari to lag. Any extension or plugin that is outdated or not correctly optimized could be the “culprit”, and you should disable or remove as many as possible.

The easiest way to do this is to use CleanMyMac X , go to Extensions > Safari Extensions (the screenshot below), here you just select these unwanted plugins, and click the “Remove” button at the bottom to clean them all at once.

Of course, you can also get this done manually, though the process will be a bit time-consuming if you have a list of extensions to disable or remove.

First, start by opening Safari, and then navigate to Safari > Preferences.

In the preferences menu, choose the Extensions icon. You’ll be shown a list of all your extensions.

If you don’t use an extension, you should uninstall it with the button on the right side. If you use it but infrequently, simply uncheck the “enable” box. This should significantly speed up Safari, especially if you have been running a lot of extensions in the background.

3: Outdated Version of Safari

Because Apple makes Safari, it usually receives updates when macOS has a new version released or when there is a necessary patch. If you’re running an old version of Safari, this could be part (or even all) of your problem.

If you aren’t on macOS Big Sur or higher, your Safari is definitely in need of an update. To check what you’re running, go to the Apple Menu in the top left corner and choose “About this Mac”.

If you’re on an older version, your window will look something like this, displaying the version of macOS you’re running:

If you’re already on macOS BigSur, it will look like this instead:

If you aren’t on the latest macOS yet, open the App Store from Finder, and navigate to updates. There will be at least one software update available, which you can expand. This will show you the update for Safari, which you can update separately or with any other updates you may have available.

4: Your Network

You might argue that the problems inside Safari are simpler to deal with, but sometimes it’s surprising that Safari isn’t necessarily the “culprit”. Your network can have a significant impact on Safari’s performance.

To find out whether your Mac has network issues, check out our other post to learn more.

To test the Internet speed, you can also use Google Fiber .

• First, open the link on your Safari browser, then press the blue “play” button, and watch as your internet speed is tested.
• The site will first test your upload and then your download speed.
• Once you have your results, you can compare them with this link , which contains charts detailing what you should expect based on the connection type.
• If your results are below expected, it might be time to contact your Internet Service Provider (ISP), especially if speeds fall far below what you’re paying for.

Note: if speed seems normal and falls in the expected ranges, then this probably isn’t your problem, and you should try some of our other solutions.

5: Your User Account or Mac Drive

Sometimes the issue runs a bit deeper than just a full cache. You could have a corrupted user account or your macOS version isn’t operating correctly. To determine if this is your problem, start by creating a second user account on your MacBook.

On the new user account, open Safari and try using it as you normally would. If Safari suddenly runs faster, it’s time to repair your normal user account.

Use spotlight (top right corner of the screen) to search “Disk Utility” and open it.

Inside Disk Utility, select your account’s disk and make sure you’re on the “First Aid” tab. Then select “Repair Disk” from the bottom right corner (if this is unavailable, choose “Verify Disk” first).

Note: If your MacBook Pro is with macOS 10.10 Yosemite or earlier, you have two buttons to click on like below.

However, if your MacBook Pro is with 10.11 El Capitan or later (you probably are), just click “First Aid” and run it to check and fix any issues it may find.

The Disk Utility will repair any problems with your account. If it isn’t capable of fixing the problem, resetting your MacBook Pro is always an alternative if a bit tedious to do.

6: Close all extra tabs

The more tabs you have open on Safari, the slower your computer can run. If you don’t know what a tab is – it’s an open window. Even if you are only looking at a single tab at a time, the other open ones are using up the CPU, which puts a demand on your computer.

Newer MacBooks are capable of keeping multiple tabs open with relative ease. But if you have 10 or 20 or even more open simultaneously, you can run into performance issues that can slow down Safari significantly.

If you are experiencing slow performance, close any tabs you aren’t currently using, and you can see an increase in operating speed. 

7: Disable search suggestions

This is another quick fix that can often speed up Safari. Not many people know this one, so write it down or take a screenshot for future use.

To turn off search suggestions, complete the following steps: 

• Click on Safari from the top of the window
• Select Preferences
• Select Search
• In the Search settings window that appears, uncheck the box that says Include search engine suggestions

This can increase Safari speeds ever so slightly and help you see improved performance. 

8: Disable DNS prefetching

If you are running Safari version 5.0.1 or later, DNS prefetching might be slowing down your MacBook. This feature allows you to load a link on a page before you click on them, leading to faster browsing. But it can also slow down your computer with multiple pages trying to load and some website-related issues.

To disable DNS prefetching, follow these steps: 

• Open the Terminal 
• Enter this text: defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
• Quit Safari
• Reopen Safari

DNS prefetching will now be disabled for another small boost to the speed of your MacBook

‘All of these behaviors are typical symptoms related to Apple’s signature Internet browser. While Safari is a light-weighted browser optimized for use on all Mac machines, issues like above might force you to resort to third-party browsers (perhaps Chrome, stay away from Firefox) that tend to be faster.”

Chrome is developed by Google. When you use Chrome, not just your searches but EVERYTHING YOU TYPE and EVERYWHERE YOU GO is sent to and tracked by Google.

Don’t be a sheep. Don’t use Chrome.

Safari running slow on Mac? 18 Ways to fix it!

Safari is one of the fastest browsers for Macs, and it’s perfectly tuned to Apple’s ecosystem. Yet, it can encounter hiccups now and then. If you’ve found yourself facing the all-too-familiar colorful, spinning pinwheel more often than you’d like, looking for ways to fix Safari running slow on Mac is understandable. 

Despite being a great browser, it’s not immune to occasional lags. So, let’s dive into how to speed up Safari on Mac and get you back to browsing with the speed you need.

Why is Safari slow on Mac?

There’s a host of reasons why Safari might be lagging or running slower than usual on your Mac. It could be anything from overloading your system with multitasking to simply not maintaining your computer or the Safari app.

Regular upkeep and a few tweaks can make a world of difference in performance. But it’s also important to note that it’s also normal for Safari to run slow during certain situations, such as browsing sites loaded with ads and videos—especially those on auto-play.

How to fix Safari running slow on Mac

Let’s explore how to make Safari run faster on Mac with some strategies.

• Check internet speed on your Mac
• Force Quit Safari on Mac
• Quit other apps
• Close unwanted tabs and windows
• Kill resource-intensive apps and processes
• Remove unwanted Safari extensions from your Mac
• Update Safari
• Restart your Mac
• Clear Safari’s cache and cookies on Mac
• Create a new user account
• Disable Search Suggestions in Safari on Mac
• Switch DNS provider
• Disable Autofill on Mac
• Scan your Mac for malware
• Update your Mac
• Disable DNS Prefetching
• Reset Safari to its factory default on Mac
• Boot your Mac into Safe Mode

1. Check internet speed on your Mac

It’s essential to first rule out connectivity issues when Safari is running very slow on your Mac. Since internet speed is vital in how quickly pages load, why not check your connection before you start troubleshooting?

Head to online speed test sites like SpeedTest.net to gauge your internet speed.

2. Force Quit Safari on Mac

Occasionally, a page or app may overtax your system’s resources, leading Safari to freeze or run slow. A quick fix is to quit Safari and start it up again. This terminates any demanding processes and gives the browser a clean slate to work from.

• To do this, go to the Dock and control-click Safari .
• Press the  Option key  → Select  Force Quit .

3. Quit other apps

If a dozen apps run simultaneously in the background along with Safari, it’s not unusual for it to become sluggish.

• Head to your Dock and quit apps you’re no longer using.
• Just look at every app with a dot below it.
• Control-click it and select  Quit .

4. Close unwanted tabs and windows

While Safari can handle dozens of tabs opened at a time, each open tab and window does tap into your Mac’s power and memory.

Excessive tabs can gradually impede your Mac’s performance, leading to longer page load times and unpredictable browser behavior.

5. Kill resource-intensive apps and processes

Aside from apps, having too many apps running can also affect Safari’s performance. Some of these apps tend to hog more resources than others. If Safari is acting up and you’re using several apps at a time, head to the Activity Monitor to see which ones consume too much power and memory. 

• To do this,  open Launchpad  → click the  Other folder → Activity Monitor. 

• Additionally, if an app is too resource-intensive, consider  creating a web app for it  instead, which generally requires less power and memory.

6. Remove unwanted Safari extensions from your Mac

Extensions allow Safari to do more, but it does come with a cost—some tend to be resource-intensive and overload your CPU and RAM.

7. Update Safari

Updating Safari on your Mac  helps ensure the app has the necessary improvements and features to run faster and smoother. For newer Macs, Safari updates are bundled with macOS updates. However, you can apply just the updates related to Safari.

• Go to System Settings , if there’s a software update available, you’ll see a Software Update Available under your Apple ID.
• Otherwise, you can head to General  →  Software Update.

8. Restart your Mac

This may sound cliché already, but sometimes, all your Mac needs is a quick reboot to fix any performance issues affecting it or any of your apps.

9. Clear Safari’s cache and cookies on Mac

Web browsers such as Safari enhance browsing by storing data like cookies and cache, which can speed up load times. Additionally, Safari keeps a record of your recently visited web pages.

Though helpful, these can accumulate over time, causing your Safari to run slower than usual. A quick tip to determine if the accumulated history, cookies, and caches are to blame is to try browsing in a private window. Since Private Browsing mode doesn’t retain browsing data, it can serve as a good benchmark for comparison.

Regularly  deleting Safari’s browsing history, cache, and cookies  is an important habit to keep Safari in tip-top shape.

• If the method above doesn’t work, you can manually delete the cache by going to  Finder .
• Go to the menu bar and click Go  →  Go to Folder .
• Enter the command below, open the folder, and drag the . db file  to the Trash.

10. Create a new user account

It’s possible that the issue runs deeper and has seeped into your user account. To check, you can create another user account on your Mac and try using Safari on that account as you would typically do. If Safari runs faster on that account, you’ll need to repair your original account using Disk Utility.

• Search for Disk Utility on Spotlight → Select your account’s disk .

• If you can’t see this option, choose Verify Disk first.

This process will repair any problems within your account.

11. Disable Search Suggestions in Safari on Mac

Safari’s Smart Search Field simplifies browsing by allowing you to enter URLs or search terms directly into the address bar. The Safari Search Suggestions feature further enhances it.

It works like Google’s recommended search results, offering recommendations such as apps to refine and intuitively guide your search experience. To turn off Search Suggestions in Safari:

• Open  Safari  → Click Safari in the menu bar → Pick Settings .

12. Switch DNS provider

The Domain Name System (DSN) is a cataloging system that translates website names into IP addresses. By default, your DSN settings are provided by an ISP. Sometimes, this may be overloaded or slow, so changing to a faster DNS provider may boost your internet speed and, consequently, Safari’s performance.

• To do this, go to  System Settings  →  Network .
• Click  Details  beside the WiFi/Ethernet you’re currently connected to.
• Select the  DNS tab.

13. Disable Autofill on Mac

To provide a more intuitive experience, Safari has an Autofill function, which completes forms detected online using stored information on your Mac. The downside is that this may sometimes cause Safari to tag.

Deselect all the types of information you don’t want Safari to autofill. Deselect all to turn off the function entirely.

14. Scan your Mac for malware

While rare, your Mac can get infected with a virus, which can inadvertently affect your Mac’s performance. Check our guide on the  most common viruses affecting Mac and what you can do to remove them .

15. Update your Mac

If your Mac isn’t running on the latest macOS, it’s best to update it to the latest version available. This is because Apple sends bug fixes and other enhancements in every update so your Mac runs smoothly. To update your Mac:

• Head to the  Apple menu  →  System Settings .
• Go to General  →  Software Update .
• If there’s an update available, click  Update Now .

16. Disable DNS Prefetching

Safari enhances your browsing experience by using DNS Prefetching to speed up webpage loading times. This process reduces the delay between when you click and when the webpage display appears because your browser already knows the address it needs to retrieve the page.

Ironically, this can slow down Safari or become unresponsive.

• To turn this off, go to  Finder  →  Applications  →  Utilities →  Terminal .

• Hit Enter and relaunch Safari .

17. Reset Safari to its factory default on Mac

If nothing seems else to work, underlying issues or corrupt browser preferences may be the culprit behind your Safari running very slow on your Mac. Resetting your Safari to its default state may fix the problem, as this reverts its browser settings to default and deactivates all the extensions. To do this:

• Open  Finder .
• Select  Go  →  Go to Folder . Then do the following, one after the other:
• Type  ~/Library/Preferences/directory  in the text field → Search for the  com.apple.Safari.plist  file → Delete .
• Type  ~/Library/Safari/  → Delete all the files in the folder except for the  Bookmarks/plist
• Type  ~/Library/Containers/ , look for Safari → Delete all the files and folders.
• Once done, open Safari. On the menu bar, click  Preferences  →  Privacy . Select  Remove All Website Data  and Reset Safari.
• Head to the Extensions tab and reactivate only the essential extensions you need. Move between the other tabs and modify other browser settings to your preference.

18. Boot your Mac into Safe Mode

Another way to troubleshoot for errors is to  boot your Mac into Safe Mode . Safe Mode starts up your Mac without launching certain software and extensions, which can conflict with Safari. It also runs a check of your startup disk, so it can help resolve underlying issues that may be affecting Safari’s speed.

While booting your Mac in Safe Mode doesn’t really make Safari run faster during regular use, it’s a helpful tool that can help you find out why your Mac is so slow and give you an idea of how to make Safari run faster on Mac.

How to Troubleshoot Safari if It’s Running Slow on Mac

This article shows how you can fix the Safari browser if it is slow on your Mac. The purpose is to help speed up Apple’s Safari or determine why it is running slow. If you are experiencing one of the following issues, you can use this article to address your problem:

• Safari is so slow and seems frozen.
• Websites are taking a lot of time to load or videos are lagging.
• A spinning beach ball frequently keeps appearing when attempting to browse the Web.
• Clicking the Safari options (history, bookmarks, etc) temporarily causes Safari to freeze or become sluggish.

There could be many reasons why you experience this issue. Follow the steps below:

1. Is the Mac up to date?

Ensure that your Mac is running the latest versions of the macOS version . Safari is a built-in app and the macOS software includes Safari. This means that updating macOS will also update Safari. You can go to System Preferences > Software Update to check for updates. And if there is an update, click the Update Now button to update your Mac.

2. Is it your Internet connection?

You may feel that Safari is sluggish because you may have a poor or unstable connection to the Internet. Use another browser (Chrome, Firefox, etc) to visit a website. Or try using multiple devices in your home. Do you still experience that your browsing experience is slow? If your answer is yes, then the problem may be your connection. Is the slowness just with one website or with all of the websites you try to visit? If the problem is with just one website, then the problem is that website. However, if all of the websites appear to be slow on all devices and/or using different browsers, the problem may be, again, your connection. If this is the case, try:

• Ensure that your Mac has the latest version of macOS (System Preferences > Software Update).
• Turn off your Mac (Apple menu > Shut Down), do not turn it on yet.
• Restart your modem/router. Simply unplug it from power, wait 30 seconds and then plug it back in.
• Wait for your modem/router to fully function (ensure that all of the indicator lights are on).
• Turn on your Mac by pressing the power button.

3. Too much cache? Clear your cache on Safari on your Mac

As you use Safari to visit websites, cache data will accumulate and this can possibly slow the browser down. Clearing the cache on your Safari browser will ensure that it’s working smoothly and efficiently. The Safari cache is a pile of temporary website data. Here is how you can clear cache in Safari on your Mac:

• Open Safari.
• Click Safari > Preferences.
• Click the Advanced tab.
• Check the box next to the “Show Develop menu in menu bar” option. Now a new menu item called Develop will appear.
• Now exit Preferences.
• Click Develop and Empty Caches.

4. Are your extensions causing this?

An extension or add-on may cause this problem. Do you have these installed? If your answer is yes, try the following:

We can turn off Safari Extensions temporarily to see if they are causing this:

• In Safari, click Safari > Preferences.
• Click Extensions.
• You will see your installed extensions.
• Turn all them off by deselecting the checkboxes.

Now check Safari. Is it faster now? If turning off extensions resolves the issue, now determine the problematic extension that is causing this issue. Turn them back on, one by one, until you find the problematic extension. After each extension, you turn it on, test to see if the problem has recurred before turning on the next extension.

5. Safe Mode

Restart your Mac in Safe Mode . Safe Mode will clear some system caches. This can improve Safari’s performance. The steps will differ depending on the Mac type you have: Apple silicon or Intel. If you do not know, go to the Apple menu > About this Mac.

Apple silicon:

• Turn off your Mac.
• Press and hold the power button until the startup options window appears.
• Click your startup disk.
• Press and hold the Shift key and click “Continue in Safe Mode.”
• Turn on your Mac and quickly press and hold the Shift key.
• Release the Shift key when you see the login window.

Your Mac is in Safe Mode . Test Safari. Then exit Safari (just restart your Mac). Then test Safari again.

Safari Running Slow? – Here are Some Quick Fixes!

If you buy through affiliate links, we may earn a commission at no extra cost to you. Full Disclosure Here…

Apple’s Safari is known to be amongst the best browsers due to its fast performance and simple interface. However, it can still run into performance issues that can be frustrating. There could be a multitude of reasons for Safari running slower than usual. So, we tried a few simple methods that might be able to fix the issue and get back on track.

Some possible reasons for this issue are the build-up of cache or cookies, outdated browsers, extensions, or plug-ins that are not being used. Once you are able to identify the issue, you can simply follow the steps to remove cache and extensions or even update the browser.

Well, let us look at everything we need to know in detail and figure out all the methods that might work best for you.

Why Is Safari So Slow?

1. build-up cache and cookies, 2. software update, 3. extensions and plug-ins issue, 4. large number of open tabs, 5. network issues, 6. limited storage space, 7. contact apple support, frequently asked questions.

Your Safari browser is running slow because of the build-up of cache and cookies. Or it could even be because you are using an outdated version of the browser, and it needs an immediate update. Furthermore, this could be simply because too many tabs are open on the system, and thus it is eventually slowing down the entire software.

As we said, this could be because of any underlying cause. You can fix all of it by simply restarting the system or the browser itself. Or you might need to try other methods that can take a few more steps. Here are some fixes you can try that worked for us too.

7 Reasons Why Safari is Running Slow + Fixes

We all know the basic idea behind using cache and cookies. They are used by websites or the system to speed up your browsing experience. However, the more you are active on the internet, the more these files are piled up over time.

Hence, there isn’t enough space for the browser or the system to store any more of these small files. So, we need to eliminate these to fix your Safari issues. Here is how you can do it.

• Open Safari Browser.
• Now, click on History on the top taskbar and choose Clear History in the drop-down menu.

• Select the time duration besides the Clear option, then click on Clear History.

The above steps will clear the history and the cookies from the site. Now close Safari and start again to check if the issue is fixed.

Here is another way you can empty caches on the Safari browser.

• Open the Safari browser and click on Develop on the top taskbar.

• Now, from the drop-down menu option, select Empty Caches or press Option + Command + E.

Another method you can try is updating the Safari browser by updating your macOS . Since Safari is an in-built software developed by the tech giant itself, they often release updates to fix such errors.

Here is how you can check for updates and update your Safari app when needed.

• Go to the Apple menu and then choose System Settings .
• Then click on Software Update.
• Wait a few seconds for the system to check for an available update. Install the update if available.

Once you update your macOS, your Safari app will also be updated. You can then wait for the system to restart and check if the app works fine.

Some extensions or plug-ins might be outdated and cause your Safari to slow down and cause performance issues. Hence, you can update or uninstall these extensions from your system.

You can follow the steps below to check which extensions you are currently using and then uninstall the ones you are not using anymore.

• Open Safari browser.
• Go to the Safari option on the taskbar and choose Settings.

• Now, click on the Extensions option on the menu bar.
• Next, choose the Extension you want to remove and select Uninstall.

You can keep doing this for all the extensions you do not want to keep and uninstall them from your browser. This will eventually speed up the performance of Safari.

Have you been currently using too many tabs on your Safari browser? Well, this could be one of the biggest reasons your Safari browser has slowed down or even glitched overall. The best way to go from here is simply close some tabs and give your browser a breather.

If that does not work, you might have to close the browser and restart the system. For this, simply right-click the Safari icon in the dock below. Press Quit and the browser will close with all its tabs.

Before trying out any other solution, it is best to check your internet connection and ensure it works properly. Your network issues might be causing the website and other downloads to slow down. 

Ensure your router is properly connected or your MacBook receives a proper internet connection. For this, you can check your internet speed through multiple sites on the web. If everything looks fine, you can try the other methods listed below.

You might need to clear some storage space on your Mac . Some apps fail to function because your system does not have enough space to run the in-built apps such as Safari.

For this, you can check the current status of your storage on Mac and determine how you can make space for the system apps to run smoothly.

• Go to the Apple menu and choose System Settings .
• Scroll down to open General and then choose Storage.

Here, you can check all the sections that have taken up the maximum space and then delete some of the files.

The last resort here is to contact Apple support for some guidance. Although you can also check for some hardware issues, it is best to speak to an executive from Apple support.

Simply visit the official Apple website and connect to an online executive where you can present your issues and try their suggested fixes.

Check our article on How to Add More Storage to MacBook’s?

You can start by updating the macOS, which will, in turn, update the Safari app as well. Moreever, you can also clear caches and cookies to help bring the safari to speed.

Safari is known to be faster on Apple devices such as your MacBook. At the same time, Google Chrome performs the best on all devices, including your smartphones. However, it depends largely on the operating system and the device’s hardware.

The fastest browser for Apple is indeed Safari. It is built for macOS and iOS devices, providing an optimized browsing experience.

The fixes to a slow-running Safari are simple. Clearing your cache, updating the app or your macOS, closing unwanted tabs, and clearing storage space are all excellent ways of ensuring your Apple search engine runs perfectly. 

If these do not work, you can check your internet connection and close the tabs you are working on. The more tabs you have opened, the slower it will work. Similarly, there are other methods too that are tried and tested to fix Safari issues, and you can try them as well before contacting Apple Support.

10 Safari Mac Browser Tips to Boost Speed and Performance

If Safari is running slow, try these top tips to get your Mac browser blazing fast again.

Safari generally provides the fastest and most efficient browsing experience for Mac users. Apple puts a lot of work into optimizing the browser's performance and energy consumption specifically for Apple hardware.

Unfortunately, this doesn't always hold up over time. Safari can become slow, bloated, and unresponsive like any other browser. Let's take a look at how to speed up Safari on your Mac in case this happens to you.

1. Update and Restart Your Mac

Restarting your computer fixes many of life's problems, including a slow browser. It should always be your first troubleshooting step for such issues. Open the Apple menu and select Restart to do so.

Once your Mac boots up, it's also worth installing any outstanding app updates , which you can find by going to App Store > Updates .

2. Close Unneeded Tabs

How many tabs do you have open right now? And how many of those tabs do you really need? Safari keeps many of your tabs active in the background, even if you're not using them. One of the easiest ways to speed up Safari on your Mac is by simply closing tabs.

If you're particularly protective of your browser session, try an extension like Tab Suspender . This allows you to suspend your open tabs to save processing power.

3. Clear the Cache and Temporary Files

Like almost all browsers, Safari keeps a cache of data from all the websites you visit. This takes up disk space, which can contribute to performance problems. It's always a good idea to blow away Safari's cobwebs once in a while by emptying the cache, particularly if you need to improve the browser's performance.

To clear your Safari cache:

• Launch Safari and click Safari > Preferences in the menu bar at the top of the screen.
• Click on the Advanced tab, then check Show Develop menu in menu bar at the bottom of the window.
• Close the Preferences window and click Develop > Empty Caches in the menu bar at the top of the screen.

4. Disable Thirsty Extensions

Safari has some excellent extensions available to install, but sometimes they do more harm than good by slowing everything down. This is particularly true for extensions that directly affect the browsing experience. A good example is TamperMonkey ($1.99), which changes how websites appear and behave with user scripts.

To isolate extension-related slowdown, try disabling all your extensions under Safari > Preferences > Extensions . To disable an extension, uncheck the box next to its name.

You can then try re-enabling extensions one by one to find the culprit.

Disabling extensions in this manner doesn't remove them. You'll need to click the Uninstall button in each entry on the Extensions tab to completely remove Safari extensions .

5. Restrict Plug-Ins and Website Access

Apple has been working to eliminate plug-ins from Safari, but they might still cause your browser to slow down on rare occasions. This is most likely if you're running an older version of Safari.

It's best to ensure plug-ins ask you before Safari starts running them. The same goes for allowing access to your Mac's camera, microphone, screen sharing, and other security settings.

Go to Safari > Preferences > Websites to see which websites have requested access to your Mac. Work through each item in the sidebar and disable access for any websites that don't need it. We particularly recommend disabling auto-play.

In older versions of Safari, you should also go to Safari > Preferences > Security > Plug-In Settings . Make sure plug-ins are set to Ask before they start running. Disable any you don't need by unchecking them. These settings aren't available in newer versions of Safari.

6. Upgrade macOS

Yearly macOS upgrades include new versions of Safari. If you don't install the latest version of macOS, you won't have the latest version of Safari. New versions of Safari mean better compatibility with the latest web technologies.

Apple's tweaking under the hood often results in faster rendering times and a speedier browser experience overall.

There's also something to be said for upgrading your operating system since many underlying issues with your Mac get patched up along the way.

To update macOS, open the Apple menu and go to System Preferences > Software Update .

7. Identify Dodgy Websites and Crashed Tabs

Safari can slow to a crawl as a result of a single problematic website. Websites can crash for all sorts of reasons, including too many scripts, auto-playing advertisements, rogue extensions, and malfunctioning embeds. Occasionally, this can bring your whole Mac to a grinding halt.

Sometimes these pages consume more than their fair share of resources; other times they crash entirely and leave you with the spinning pinwheel of death. To rectify the situation:

• Launch Activity Monitor under Applications > Utilities .
• On the CPU tab, click on the Process Name column to arrange processes by name and find Safari .
• Now look at the % CPU column and systematically close your Safari tabs to see which ones have the biggest impact on your CPU usage.

8. Make Sure You Have Enough Free Space

A lack of free space on your disk can have devastating consequences for your Mac's overall performance. A Mac with limited free space is more likely to freeze, stutter, and crash. This can cause your whole system to run slowly, but Safari is often one of the first apps to buckle as individual resource-intensive tabs become unresponsive.

For best results, maintain a healthy buffer of 10GB or more of free space. Follow our tips for freeing up space on your Mac if you run out of options.

9. Fix Other macOS Performance Problems

Boosting overall system performance also speeds up Safari on your Mac. This is because there are fewer resources tied up in non-critical tasks, so more of them are available for Safari.

Take a look at these common mistakes that might slow down your Mac . They include having too many apps running in the background or starting up at login, which you can change by going to System Preferences > Users > Login Items .

10. Check for Network Connection Problems

If your internet connection is slow, Safari will also feel slow. To isolate connection problems, find out how to test your internet connection speed to see if that's to blame.

You might need to change your DNS settings to fix it, which you can do by going to System Preferences > Network > Advanced > DNS . Use Google's Namebench to find the fastest DNS settings for your network.

Keep a Backup Browser Installed Just in Case

Although you can follow all the tips above to speed up Safari on your Mac, it's also worth keeping a backup browser installed as well. These are useful to have for stubborn websites that aren't optimized for Safari or in case you need to use a browser extension that's only available on one browser.

10 Fixes When Safari Running Slow on Your Mac

How to fix this annoying problem

Apple touts Safari as the fastest browser out there, which may be true on iOS, but I regularly use Chrome on my Mac because Safari is just too slow. Sometimes a webpage won’t load or I won’t be able to navigate back and forth between pages or I can’t scroll without lagging.

It’s extremely frustrating considering Safari comes included with OS X and you expect it to just work. When it does, it’s a great browser, but when it doesn’t, you literally have to switch to a new browser.

In this article, I’ll mention all possible ways you can go about trying to speed up Safari on your Mac. If you have your own suggestions, feel free to let us know in the comments.

Also, be sure to check out our YouTube video where we cover a couple of other possible reasons for slow Internet that may have nothing to do with Safari:

Method 1 – Cache, History, Extensions

If you’re a heavy web user and you don’t have a lot of space left on your Mac, it might be worth emptying the cache, disabling extensions, and clearing up the history to ease the load on Safari. In order to do this, you first have to go to Safari and then Preferences .

Click on the Advanced tab and then check the Show Develop menu in menu bar box at the bottom of the dialog.

Exit the Preferences dialog and click on Develop in the Safari menu. Go ahead and click on Empty Caches . Once the cache is empty, click again on Develop and choose Disable Extensions .

Finally, click on Safari and instead of Preferences like we chose above, click on Clear History .

In the drop-down box, make sure to choose all history and then click the Clear History button.

Method 2 – Manually Clear Cache.DB File

The above steps should clear the cache in Safari, but if something is not working properly, it may not do so properly. In this case, you can manually do it. Open Finder, then click on Go and Go To Folder at the bottom.

Now copy and paste the following path into the text box and click Go .

Finally, right-click on the Cache.db  file and choose Move to Trash . Make sure Safari is closed when you are doing this step.

Method 3 – Install Latest OS X Version

I’ve noticed that quite a few people who purchase Macs simply do not update their systems to the latest version of OS X. Even though we are on El Capitan right now, I have friends running on Mountain Lion, Mavericks, Yosemite, and even Snow Leopard!

If you don’t update OS X, you won’t get the latest version of Safari either. This means you could be stuck several versions behind and will be missing out on all the improvements and optimizations of the newest version.

The simplest way to upgrade is to go to the App Store and click on the link for the latest version of OS X, which is usually on the right-hand side.

Method 4 – Turn Dashboard Off

If you’re still using an older Mac (2010 or earlier), you might have a graphics card issue. You can try something simple to see if it helps in Safari. I’m talking about disabling the Dashboard feature in Mission Control.

To do this, open System Preferences and then click on Mission Control. In the drop-down next to Dashboard , select Off .

This is not some surefire fix, but it has worked for some people, including myself. I have a Mid-2009 MacBook Pro and the dashboard was definitely slowing things down.

Method 5 – Change Search Settings

Another thing you can try is to change the search settings in Safari. Open Preferences  in Safari and then click on the Search tab.

Try changing the search engine to Bing, restarting Safari, and see if there is any difference in the speed. Change it back to Google and then check again. You can also try unchecking all the options like search engine suggestions, Safari suggestions, a quick website search, preload top hit, etc. to see if that makes a difference.

Sometimes on a very slow Internet connection, all of these extra features may cause Safari to be even slower.

Method 6 – Change Network Service Order

If you have a machine that is connected to both WiFi and Ethernet, your issue could be caused by being connected to the network in two different ways. To see your connections, go to System Preferences and then click on Network .

You could try disconnecting one network source and seeing if that makes a difference or not. Switch to only the other one and test too. If you want to keep both connected, read on.

By default, one connection will get priority over the other. As you can see above, my WiFi connection was getting higher priority than the Ethernet connection. You can change this by clicking on the little settings icon (gear) at the bottom of the list box.

Click on Set Service Order and another popup will appear where you can reorder the connections by dragging and dropping.

I moved Ethernet to the top and then clicked OK. After that, make sure you click Apply to on the System Preferences dialog.

Method 7 – Delete Preferences File

This probably won’t make much of a difference, but it’s worth a shot. Go to Finder , click on Go and then Go to Folder .  Type in the following path:

Scroll down the list till you see com.apple.Safari.plist and delete that file.

Method 8 – Use Different DNS Settings

Sometimes it may not be Safari causing the issue, but your DNS settings. By default, you’ll be using the DNS provided by your ISP, which is fine most of the time. However, using a public DNS might result in faster browsing.

My favorite is Google Public DNS, which I use on all my computers. Check out my article on the best public DNS servers you can use for free.  To change the DNS server for your connection on OS X, you need to open System Preferences , click on Network , select the connection and then click on Advanced .

Go ahead and click on the little + icon and then type in the IP addresses of the new DNS servers. Using Google has sped up my browsing not only in Safari, but also in other browsers.

Method 9 – Log Into Another Account

Sometimes the problem is with the user account you are currently using. It’s worth creating another user account (takes 1 min), logging into that account, and then running Safari. If it’s suddenly faster, then there is a problem with your user account. You can try to fix the problem by using Disk Utility. You can go to Spotlight and type in Disk Utility to open the dialog quickly.

Click on your hard drive in the left-hand pane and then click on the First Aid tab. You’ll be asked if you want to run First Aid on your hard drive, so click Run .

Method 10 – Reinstall OS X

This may sound a little extreme, but it’s kind of similar to how you have to reinstall Windows every year or so because it becomes so bloated. Unfortunately, OS X suffers from some of the same issues, especially if you have always kept upgrading to the latest version of OS X without doing a clean install.

I upgraded from Mountain Lion to Mavericks to Yosemite to El Capitan before doing a fresh install of El Capitan, which made things significantly faster. It’s definitely worth a shot because it also made every other app load a lot faster too.

Those are about all the possible solutions I could find to fix a slow Safari problem. If you have any other suggestions, feel free to let us know in the comments. Enjoy!

5. Clear Safari History

Removing Safari history is one of the oldest ways to get rid of all the existing clutters. So, in a situation where a speedy Safari is more important than the piled-up history, you shouldn’t hesitate to wipe out all the data. Keep in mind, it will remove Safari history on all the devices synced with the same Apple ID . To do it, open the Safari -> Safari  menu. Then, click on Clear History. After that, click on the drop-down menu and choose All History . Then after, click on Clear History to finish.

6. Update DNS Setting on Your Mac

• Click on the Apple menu -> System Preferences -> Network.

7. Flush Out DNS Cache

Simply launch Terminal on your Mac and then enter the below-given command and hit the return key.

mag jade – Well, that’s better than, “contact your local dealer”, right?

I read dozens of tips about this problem, and none of them helped. I went thru the websites I use the most and reset the page zoom to 85%. I am no longer frustrated, everything is acting normal again. Hope this helps.

This shouldn’t work like that. Users should not have to do all that stuff to be able to run their app normally! I feels like buying a car and the salesman tells you that the fourth wheel is in the back and you will have to install it yourself and that the manual is in the glove box and that you will find the instruction on page 172 after opening the hood and pressing on the green button to your right… Come on!

Why is My Safari So Slow on Mac and How to Fix It

Whether you use the Safari internet browser for your everyday work, school work, online shopping, or simple internet browsing, having it work slowly can be extremely frustrating. This is completely understandable, but don’t worry we are here to help!

As someone who frequently helps people fix up their slow Macs, I can say from experience that Safari can often be the cause of a lot of problems. But the good news is that you don’t have to put up with Safari running slowly—there are a few quick troubleshooting tips you can use to get back in business.

Let’s explore why Safari is running so slow on your Mac and how you can fix it.

Table of Contents

Key Takeaways

Solution #1: verify your internet connection, solution #2: force quit safari, solution #3: update macos, solution #4: close excessive tabs, solution #5: disable extensions, solution #6: turn off icloud private relay – icloud+ only, solution #7: disable search engine suggestions, solution #8: disable autofill, solution #9: update dns server, solution #10: run first aid on ssd , safe mode – intel mac, safe mode – apple silicon mac, solution #12: use a 3rd-party web browser cleaner, final thoughts.

• Safari has many features that attempt to either help you as the user or make the experience faster. Unfortunately, Safari can sometimes get bogged down.
• Your internet connection should be one of the first things you check. Make sure everything is functioning properly here.
• You can get Safari out of a jam by Force Quitting , and reopening.
• If that doesn’t work, you can check your extensions , your iCloud Private Relay , and Autofill to ensure that your Safari is running as fast as possible. 
• The DNS server can sometimes cause issues with Safari running slowly, so make sure that it is updated. 
• If none of that works, you can also check to make sure your boot drive and your startup options are working properly. Run First Aid on your SSD and boot into Safe Mode to finish troubleshooting.

While Safari is preinstalled on your Mac and is updated using macOS, this doesn’t mean that it will always work perfectly. When Safari runs slow on your Mac, it can put a damper on your whole experience. You end up waiting on your computer and getting frustrated. So, what is causing this? And how can you fix it?

Here are some ways that we can hopefully get your Safari speed up.

This may sound obvious, but you may be surprised how easy it is to overlook losing your internet connection or other connection problems. Safari may not be working or may be running extremely slowly because of a faulty internet connection. 

There are multiple items that could affect your internet connection. Be sure to verify all of the following: 

• You have full internet connectivity from your internet provider (if you are able to reach it, speedtest.net is a good way to determine if your internet is working to its fullest capacity).
• Your modem and/or router are in working condition (the lights on the device will help you determine this. Look at or find the owner’s manual for your device if you have questions)
• There are not too many devices on your network (I would recommend taking off some that you may not think of and are not currently using, such as phones, tablets, gaming consoles, and smart home devices).

By force quitting the Safari application , we are forcing any processes that may be stuck to stop. This can help Safari fully restart and stop trying to load something that may not be properly loading. To force quit Safari, take the following steps:

Press the Command-Option-Esc keys simultaneously on your keyboard.

Choose Safari from the menu and choose Force Quit .

Click on Force Quit to confirm.

As we have briefly discussed earlier, Safari is an application that is fully managed by Apple and updated along with macOS. So, if there is a problem with the Safari application itself, it is likely that Apple already knows and has released a patch to address it. 

To ensure your Mac is up to date with the latest version, take the following steps:

Using the Apple Menu, choose System Settings from the drop-down.

Navigate to General on the left, then Software Update on the right.

If there is a software update available, choose Update Now and follow the onscreen prompts to update macOS.

If you are someone who never closes your browser tabs and has dozens of pages open at once (like I am guilty of doing most of the time), then I would suggest closing a good amount of them to get Safari working at a better speed. 

Having a large amount of tabs open, even ones that are not currently in use, uses not only a lot of processing power but also a lot of Random Access Memory (RAM) . 

Both of these items have a large impact on how the applications on your Mac run and can cause the Safari application to slow down significantly. So, close all possible tabs.

Extensions, also known on some internet browsers as plug-ins can be very helpful features. The most popular of these are ad blockers, coupon finders, and grammar checkers. If you use any of these or others, it is possible that they could be slowing down your Safari. 

It is also possible that extensions could have been inadvertently downloaded from the internet and enabled themselves. Check to make sure that there are no unrecognized extensions or an excessive amount of extensions enabled. 

With Safari Open, click the Safari menu and Settings from the drop-down.

On the top, choose Extensions .

On the left, the blue check marks indicate that the extension is enabled. Click these to show the gray checkbox and disable the chosen extensions. 

If you find any extensions that you do not recognize, select them on the left (it will be shown in blue) and click uninstall on the right. Follow any onscreen instructions to finish uninstalling. 

While iCloud Private Relay is a convenient and easy safety feature, however, it requires that your internet browsing passes through Apple servers prior to reaching your computer. This means that it could slow down your internet speed. 

Click the Apple Menu and System Settings .

On the left, click your name, and on the right click iCloud .

Scroll down to the iCloud+ features and ensure that Private Relay is turned off. If it is not, click on it and click the slider to turn it off. You may be asked to confirm by clicking “ Turn off iCloud Relay .”

Search engine suggestions are a predictive feature when you are using Safari. They are designed to predict what you may be searching for and help you to find it easier. However, it is possible that they can be slowing down your Safari. Take the following steps to check:

With Safari open, choose the Safari menu and Settings.

In the Search tab at the top, deselect the “Include Search Engine Suggestions” check box. It will show as a gray box when it is deselected.

Another Safari feature, while helpful when it works properly, can also slow down the application is the Autofill feature. Autofill sometimes has a hard time accessing the information and may cause Safari to freeze. 

In Safari Settings (described how to reach above), Choose the Autofill tab at the top. Deselect all the Autofill features below. The items are deselected when they show a gray box instead of a blue checkmark.

A Domain Name System Server (DNS Server) is a program that tells your computer and the internet what IP Address your computer or a website is using. By updating your DNS server you can not only improve your internet speed (and therefore your Safari speed), you can also improve your security. 

Some of the most popular DNS Server IP Addresses are those for Google, 8.8.8.8, and 8.8.4.4. The DNS Server 1.1.1.1 is allegedly considered to be the fastest in the world (though I am not confident in how or when that was recently confirmed). 

To update your DNS server, take the following steps:

Choose the Apple Menu and System Settings .

On the left, select Network , and on the right, select Details under the Wi-Fi section.

On the left, choose DNS . On the right, use the + button to add any of the DNS Servers that we have discussed (or others you may have found in your search). 

Note : it is OK to have more than one DNS Server—if one is down, your computer will use another one in your list.

Your Solid State Drive or SSD is a critical piece for the speed of your Mac. If all the other fixes up to this point did not work, it is possible that there may be an error on your SSD. First Aid will automatically check and fix most errors related to the formatting of your SSD. 

Open Disk Utility in Launchpad.

Choose First Aid and follow the onscreen instructions.

Solution #11: Boot in Safe Mode

Lastly, Safe Mode is a great way to determine if you are having further issues that are causing Safari to be extremely slow. Safe Mode disables your startup settings and features and any third-party items. If your Safari is running slowly for either of these reasons, you will be able to see using Safe Mode. 

Take the following steps to boot into safe mode, depending on which type of Mac you have:

• Restart or turn on your Mac and press and hold the Shift key.
• When the login window appears, you can release the key and login.
• You may be asked to log in again, do so. You will see Safe Mode in the menu bar if this was successful.
• Turn on your Mac and press and hold the power button until you see the Loading Startup Options screen.
• If asked, select a volume.
• Press and hold the shift key and click Continue in Safe Mode. Your Mac will automatically restart.
• If successful, you will see Safe Mode in the menu bar.

Sometimes Safari doesn’t work properly when you have too much junk on your computer. A good 3rd-party application like CCleaner or CleanMyMac X can work wonders to optimize your system by getting rid of junk, including things like browser data and temp files.

CCleaner for Mac , for example, has a Browser clean-up tool that automatically scans and removes browsing data, caches, temporary files, cookies, and other tracking data.

This can go a long way in speeding up Safari, and even helping out the rest of your computer too. While there is a paid version of the software, you can get quite far with the free version. So, it is worth a shot if you want an easy solution to Safari running slowly.

We have covered a lot of ground and talked about a lot of different options that could be causing your Safari Application to be slow. We first explored the more simple options, such as your internet connection being down, your Safari application needing to be updated, having a lot of tabs open, and clearing history. 

Your extensions possibly cause loading problems, your iCloud Private Relay, Search Engine Suggestions, and Autofill are also things you should check. If all else fails, you should look at two pieces of your Mac that could be affecting Safari as well, your SSD and the startup options.

If the rest of your Mac seems to be running fine enough to download another application, you could try a 3rd-party tool like CCleaner to clean up browsing data and other junk that could slow down Safari.

How to Fix Safari Running Slow on Mac? 4 Useful Tips to Try

Safari as the Mac default browser, is developed by Apple based on the WebKit engine. Apple touts Safari as the fastest browser out there, which may be true on iOS, but it doesn't work the same way on Mac because Safari is just too slow. Sometimes a webpage loading seems like taking forever, which is so frustrating. And you won't be able to navigate back and forth between pages. Why is Safari running so slow on Mac?  Here we listed some possible reasons and shared some tips to make your Safari faster.

1: Overworked Cache and History

Like all other browsers, Safari stores information about every website you visit as browsing history automatically. Elements of those websites like images and html files are saved to cache so that pages load faster next time, which puts an additional burden on the browser. Overworked Cache and History may be the biggest 'culprit'of slowing Safari. So, try getting rid of the dead weight and see if Safari is still slow afterwards. Here's how to erase the data in the cache so that Safari can work faster.

Clean Up History in  Safari

1. Open Safari

2. Find History in the menu bar (or click Safari then choose Clear History)

3. Click Clear History at the bottom

4. Select the time span and hit the Clear History button.

You can also manually clear clear the Cache.db files

1. Open Finder

2. Click Go and Go to Folder at the bottom

3. Past “~/Library/Caches/com.apple.Safari/Cache.db” and click Go

4. Right-click on the Cache.db file and choose Move to Trash

  2: Buggy and Bad Extensions

Extensions enable users to tailor Safari functionality and behavior for individual needs or preferences, and let you do a ton of convenient extras in a browser, like storing passwords or translating words with a click. But being third-party add-ons, they can impact Safari's performance in unexpected ways, especially if they aren't regularly updated.

Tips to fix:

Disable  the Extensions from  Safari

2. Find Preference in the menu bar

3. Go to Advanced tad

4. Check mark Show Develop menu in the menu bar

5. Click on Develop in the menu bar

6. Select Disable Extensions

1. Close Safari

2. Open Finder and use the Command+Shift+G shortcut

3. Enter “~/Library/Preferences/ “ into the popup and hit Enter

Login a new User Account

1. Open Apple menu

2. Find System Preferences

3. Go to User and Groups

4. Create a New Account and put it in use

 4: Outdated Version of Safari or Low-speed Network

Safari is constantly updated. Outdated version of Safari may act slower than the latest version. So please keep your Safari up to the latest version. A low-speed network surely will drag down your browsing speed. And there are many causes to a low-speed network such as the internet itself, too much running programs at one time or Mac overloaded, etc. All you can do is update Safari to the latest version and clean up your Mac to make a lighter browsing.

On macOS, Ventura, Sonoma,

Step 1: Open the Apple Logo from the top menu > Select System Settings .

Step 2: Select WiFi from the left sidebar > Click on Details next to Connect WiFi.

Step 3: Choose Proxies > Disable the toggle Auto Proxy Discovery > Tap OK to Apply the changes.

Step 2: Click on Search Tab > Uncheck “Include safari suggestions “.

Step 3: Here’s the below screen , that you miss after disabling this option.

Solution #3. Disable DNS Prefetching in Safari Mac

Is your Mac sending DNS Queries to the network via Router , and Your Router can’t handle such requests on time? As a result, you will get a slow response from the internet. If the DNS Prefetching is enabled, then your Safari browser on Mac sends a DNS Request to load the website the very first time. So, turning off DNS Prefetching on your Mac Safari is a Great solution if this happens with your System. Below I recommend trying Alternate methods for disabling DNS Prefetching on Mac or Macbook running on any macOS.

Change DNS Service Provider for Slow Safari

By default, our DNS settings are provided by the ISP. Instead, this time we will try to use public DNS, which might boost up Safari. The best DNS server is Google DNS; probably everyone, including me, is using Google DNS. This action does not only help Safari but also gets the solution for “How do I fix slow Internet on Mac?

Step 1: Go to the Apple Logo from the top Menu > Select System Settings .

Step 2: Select Wi-Fi from the left side > Click on Details next to the connected WiFi Name.

Step 3: Select DNS > Click on ‘ + ‘ to add a new Public DNS Address on Mac . For Example, Google Public DNS, 8.8.8.8 and 8.8.4.4 > Click on OK to Apply the changes .

On MacOS Monterey & Earlier

• Step #1: Click to open the “ Apple Logo ” from the Top Mac menu and then open “ System Preferences ”.
• Step #2: Open “ Network ”.
• Step #3: Select the network on which your MacBook is connected.
• Step #4: Click on “ Advanced ”.
• Step #5: Now tap (+) and add a DNS server.

To Use Google DNS , Enter the Below Public DNS Address, Enter 8.8.8.8 and 8.8.4.4 are the Google DNS servers for you.

Or You Should Use OpenDNS

Enter 208.67. 222.222 and 208.67. 220.220 in the list. Click on OK to apply changes and test internet speed on Safari.

Alternate Method to Disable Prefetching in Safari Using Terminal

This method is also helpful to disable DNS Prefatcinhg on Mac Using Terminal, Open Terminal under the utility folder.

Step 1: Launch Finder on your Mac > Click on Go From the top Menu > Choose Applications.

Step 2: Choose Utility Under the Applications folder.

Step 3: Select Terminal under the Utilities.

Type the below command, and Hit the Return to run command,

defaults write com.apple.safari WebKitDNSPrefetchingEnabl

Force Quit Safari and Re-open Safari browser to test it. If sometimes time is not working fine after disabling DNS Prefetcinhg, then turn it on again; using this command,

defaults write com.apple.safari WebKitDNSP

Also, you check internet speed using an online free Speed testing tool. www.fast.com by Netflix. Also,

Don’t miss out on other essential settings; these will improve your Safari Browsing speed without losing Privacy and switching to a third-party browser.

Solution #4. Open Empty Page on Safari: No More Load every time

Had issues with slow new tabs as well. We fixed it by opening an empty page instead of the starting screen. Safari Browser has too many hidden customizations that most Safari users don’t know.

Open Emply blank space is a great tip to start quick browsing and open on your Mac. Follow the below steps,

Step 1 : Launch Safari on your Mac.

Step 2: Click on Safari From the top Mac Menu > Select Settings/Preferences .

Step 3: Tap on General Tab > Select New Window opens with Empty Page and New Tab Open With Empty Page . Select these options from the dropdown.

That’s it. Now, your Safari page will not load any data on the New Tab or Window, but you should check What’s loading with the webpage when you open it. Along with page files, Installed Third-Party Plugins and Add-ons also check and gather details from the page. Sometimes that’s unnecessary, So disable or remove Unused Plugins or Add-Ons. Also, Keep all up-to-date.

Solution #5. Force Close and Re-Launch With the “Shift” Key

Your Safari Browser is slow because the affected website is opened in the background; some laggy websites consume more Memory than your Mac, and that’s the cause of slow down Safari performance. TO quickly get it out, Mac users must Force close Safari and Relauchc with Refresh Safari memory.

• To Force close the Safari browser, Press Command + Q to force close the safari browser.
• Press the Shift key from the keyboard. Click on Safari from the launchpad to relaunch it. So your Safari browser loads just like opening it the first time.
• That’s it.

If Safari is not loading the image, Data [ Why are images not showing up in Safari on my Mac? ] for a specific website, then you should check with the Safari Private window.

Solution #6. Test With Private Window

Safari Saved lots of data from the internet in cache and cookies to load faster on the following visit to the same website. Private Browing mode, Doesn’t interest old data saved on Mac or Naver keep new data. So that’s a great way to test the Actual Speed of your Safari browser.

Step 1: Launch Safari on your Mac > From the Top Mac Menu, Click on File > Tap to New Private Window .

Step 2: In the Next Screen, Open the Private Browsing Window on Safari.

Start Doing a Safe search without loading extra Plugins or Safari Extensions installed on your Mac.

Solution #7. Test Other Safari Plugins and Add-ons

An outdated or unsupported Safari extension installed on your Mac gives a slow browsing experience. So, I recommend disabling Safari Extension or Update Pending update from the Mac App Store. Based on experience, some extensions cannot load websites like youtube on a standard browser, but Private browsing allows to open websites. Because the installed Extension will not load on Private browsing, that’s proven you have a problem with Extensions.

Step 2: Now, From the top Menu, Click on Safari > Choose Settings/Preference .

Step 3: Go to the Extensions tab and Select the Extension in front of the name from the first left panel, So the Extension will be disabled. Next, we can uninstall from there as well.

Update Safari Extension on Mac : Open App Store on Mac > Search Extension, then Click on the Update button to download and install New updates with the latest macOS.

It could have happened due to an unhealthy add-on run on your Mac for Safari. Some extension makes Safari YouTube fullscreen lag and Safari Weird behavior.

“However, the reason behind this is, the person who have Mac or iPhone they face any problem in Safari, they move to Google Chrome.

Instead, they should try to fix Safari complications”

looool. No, they should use whatever works. Safari has no excuse, I’m sorry.

PS: Yes I miss the handover and shared ios macos tabs too… but, a non-functional browser is a non-functional browser…

PS2: I am still wasting time with relogins from your fist solution… So you say I should reinstall Mojave… when there are other browsers that work just fine… again: looool

With Windows 7, Google was fast downloading. I have recently switched to an iMac and have been driven mad by the slowness downloading web pages – sometimes it sticks part way through and I get nothing. I switched to Bing – that was as slow. In desperation I tried DuckDuckGo. Pages are downloaded instantly. I have no idea why, but it work, so I’ll stick with it.

Solution 10: how do you reinstall Mojave? Thanks

For your information, I have restored Safari normal speed on Catalina by deactivating my Intego Netbarrier suite

I upgraded my MacBook Pro to Catalina a couple of weeks ago and all was good. Today I upgraded my MacAir and I basically can’t connect to the internet using the wifi that I used before to download Catalina and the same wifi that I am using on the Pro to find your website and to send this message. I tried deleting the cache and reopening Safari and restarting but still nada.

What’s up with that?

How to Fix: Safari Running Slow on Mac

Safari is a great browser, but like all browsers, it’s not immune to problems. One issue Mac users, in particular, face is Safari running slow.

You may see the beachball running forever! Or pages take too long to load, often with just text showing in all the wrong places. And sometimes, web pages are displaying fine, but you still see the loading symbol on the tab.

All these symptoms are signs of a slow-performing Safari. However, you can diagnose the issue and quickly resolve it to speed up Safari.

There could be several underlying causes behind this issue, so you must examine each possibility one by one to get to the bottom of it.

Table of Contents

Why is Safari Running So Slow On My Mac?

Before we talk about the possible reasons behind Safari running slow, it’s essential to understand that it’s normal for this to happen. Many times, it’s not entirely the browser’s fault, as the website itself is slow to load. This is true for those heavier websites with lots of graphical designs and video ads.

So it could very well be that the website you’re trying to reach is loading slowly in the first place. Secondly, it could be a slow WiFi connection with low internet speed. To pin that, you can try running other websites or, better yet, run a speed test online.

Once you’ve ensured that it’s not the website or your internet connection, perhaps it’s one of the following issues:

Safari also uses the cache on your Mac. This cache is a temporary memory that stores information you frequently need to make things a little faster. This could be the web addresses you frequent, files you access over the network, or passwords you use to sign in to accounts on different websites.

There’s only so much this cache can hold. Therefore, when it’s complete, Safari is forced to adopt another method, making it slow. This can happen from time to time, incredibly if you search and use many websites on Safari.

The quick solution to resolving an entire cache issue is to clear history. This will include all your browsing history, including cache. However, you can also make the cache exclusively clear.

Here’s how you clear history on Safari on Mac:

• In the Navigation menu on top of the Window, click on History.
• Select the last option: Clear History and Website Data.
• A pop-up will appear asking for the duration of history to delete, so select ‘all history’ from the dropdown menu.

Here’s how you clear cache:

• Click on Safari > Preferences
• In the Preferences panel, select Advanced in the top menu
• Check ‘Show Develop Menu in Menu Bar’ and close Preferences
• A new ‘Develop’ Option will appear on the Menu Bar, so click on it, then select Empty Caches.

Now, close Safari and relaunch it to see if it’s working faster.

Bad Extensions

It could very well be a bad extension causing Safari to run slow. You probably have noticed that Safari isn’t great with the Flash plugin either.

Extensions can be helpful, as they help us get things done faster without needing to switch between windows or applications. However, sometimes you don’t update the extension, or perhaps the developers leave some bugs.

This problem can be solved simply by disabling or removing the extensions. If you use several extensions, you can remove them one by one to see which one does the trick. Also, you can remove all of them with a much easier process (discussed later).

Here’s how you manually disable or remove Safari extensions:

• Go to Safari > Preferences
• Click on Extensions from the top menu
• You’ll see a list of your extension with an Uninstall button against each
• Click on Uninstall to permanently remove the extension
• Alternatively, uncheck the Enable box to disable the extension

Disabling or eliminating Safari extensions frees up space and may improve Safari’s performance.

User Account Issue

If clearing Safari history and removing third-party add-ons didn’t do the trick, perhaps the problem could lie with your user account. To check if this is the underlying issue, create a new account. Once created, open Safari and use it to check if it usually works.

If it does work usually and isn’t running slow, you need to Repair Disk.

• Use Spotlight to search for Disk Utility.
• Select the account’s disk and make sure to stay on the First Aid tab.
• On the bottom right corner, click on Repair Disk.
• For those using Macbook Pro with El Capitan or later version, click on First Aid from the top, and it will automatically scan for issues and resolve them.

After closing Disk Utility, check if Safari is faster.

Outdated macOS

If you’re running something older than macOS Sierra, the Safari is slow because of the old macOS. When the new version of Safari is released, Apple updates it with a new version of macOS or sometimes through a patch. Either way, it means it’s time to upgrade your macOS.

It’s always a good idea to be on the latest version of the macOS, so make sure to run your Mac on the latest operating system version.

If you want to find out which version you’re running, go to Apple Menu, then click on About this Mac. A window will open with system information, including the OS version.

It would help if you ideally were on the latest macOS Big Sur or, at the very least, macOS Sierra.

How to Make Safari Run Faster?

Besides the possible issues and solutions above, there are other relatively more straightforward solutions to this problem.

Close All Extra Tabs

This is the easiest solution that can give Safari an instant boost. The more tabs you have on, the more memory and processing power Safari uses, which, in turn, slows it down.

Some people have dozens of tabs open while they are just using two or three at the time. You need to stop multitasking and perhaps stick with one or two tabs only, at least when Safari is running super slow.

Newer Macs have more processing power and more significant memory so that you may get away with even 20 or 30 tabs open simultaneously. Nevertheless, there’s a limit to their capabilities too. So don’t open more tabs than you need.

Besides, having so many tabs open at the same time is just clumsy!

Close Other Applications

You may also be able to speed up Safari by simply shutting other applications. If you’re using Safari simultaneously as you’re using other heavy applications, you may notice a drop in Safari performance. It may not necessarily be loading pages slowly, but acting slow overall, like switching between tabs or scrolling down pages.

Therefore, try closing any other applications you have running and see if that affects the Safari speed.

Disable DNS Prefetching

DNS Prefetching is a feature on Safar version 5.0.1 or later. It loads a link before you even click on it. That could be slowing down the browser. It can also cause the problem in conjunction with website-related issues.

Launch Terminal and type the text: defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false. After this, restart Safari.

Disable Search Suggestions

Simply turning off search suggestions may do the trick. Here’s how you do it:

• In Safari menu > Preferences
• Select Search from the top menu bar
• Uncheck the box ‘Include search engine suggestions.’

Delete Preference File

This solution probably might not make a big difference but is harmless enough to be worth trying. Go to Finder. Type in the path ~/Library/Preferences and scroll down to com.apple.safari.plist and delete the file.

Restart Mac

Yes, sometimes, a simple restart operation can get things back to normal. So try that as well!

Reinstall macOS

Consider this as the absolute last resort, but if everything else fails to resolve this issue, you may want to reinstall macOS. You won’t lose any data, but only the settings will be reset. The process isn’t that hard, but it is time-consuming. You can find the reinstall macOS option in the utilities.

Click on reinstall macOS and follow the steps.

Safari running slow on Mac can be incredibly annoying. As you can see, anything from an overworked cache to an older macOS version can cause the problem. However, to resolve it, you need to apply each solution one by one.

Make it a habit to clear cache and Safari history periodically so this problem doesn’t occur. Also, make sure you’re on the latest versions of both Safari and macOS.

More often than not, the culprit could be your very own internet connection, so double-check that by running different applications and perhaps by connecting to another network. If Safari runs fine after connecting to another network, you have a slow internet speed.

Aside from the stored website that you visited, there are also other aspects like HTML files, and images that are all saved in your cache which is actually another burden for the browser resulting in a slow response whenever you try to use it. Here is the fix for this.

How to Clear Your Browser’s History and Cache：

PowerMyMac's Privacy is one of the best browser cleaners today. This is the perfect tool that you can use for you to improve your online experience when using your Safari browser. It can clean up your junk files, cookies, and your history on your browser . It can also remove any deceleration reasons and can clear up privacy traces for you to help protect your confidential data.

Here is how to use the iMyMac PowerMyMac 's Privacy:

• Download PowerMyMac then have it installed on your Mac.
• Launch the program to choose Privacy and scan your browsing data.
• Once that the scanning process is complete, you will see a list of browsers that you have on your Mac.
• Choose Safari and select the browser cache, histories, browser cookies that you want to clean up .
• Click on the CLEAN button and PowerMyMac will begin to clean up your Safari browser.

If you need the manual methods to fix Safari slow to load, we also provide:

Clear your Safari’s history:

• Launch your Safari browser on your Mac.
• Then click on History in the menu bar.
• Choose the Clear History option
• Choose the time span and then click on the Clear History button again.

Doing the steps above can help you clear out your history in your Safari browser. However, if in case you do not want to lose your browser’s history and you only want to get rid of your cache, then here is what you should do.

• Launch your Safari browser on your Mac
• Click on Safari in the menu bar.
• Then, click on Preferences
• Choose the Advanced tab.
• Then put a checkmark on the Show Development menu in your menu bar.
• Click on Develop from the menu bar.
• After that, choose Empty Cache.

Tip: In case the Safari is quite slow and you want to uninstall it and then reinstall it again, you can also use this app uninstaller to completely remove it .

Reason 2. Corrupted Preferences

Once that you have assigned a homepage or search engine or if you choose where you would want to save all your downloads from your Safari browser, it is all stored in a preference file.

Because of this, once that this file becomes corrupted, then this will start an issue on your browser. If you are experiencing any issues in using your Safari browsers such as lags or freezing, then there is a tendency that the problem is with preference. Here is how you can fix this.

How to Remove Your Preference File?

Here, once that you have deleted those corrupted preference file, then your browser can easily generate a new one. Here is how you can do this.

• Close your Safari browser.
• Launch Finder on your Mac and use these keys: Command + Shift + G .
• Then enter the following in the pop-up and press Enter: ~/Library/Preference/
• Then, go ahead and look for the file name “ com.apple.Safari.SafeBrowsing.plist ” and then click Delete.

Reason 3. Extensions That HaveBugs

Your extension has a lot of extras in your Safari browser such as it stored passwords or it can translate words with just a single click. However, since it is a third-party add-on, then this could have an effect on the performance of your Safari browser.

How to Delete your extensions?

For you to be able to determine which is causing a problem to your Safari browser, go ahead and run a test. Here is how.

• Choose Safari in your menu bar.
• Choose Preferences.
• And then, choose the Extension tab.
• Uncheck all the extensions one by one and find out if the problem will be gone.
• Once that you have determined the problem, just go ahead and click on the Uninstall button beside the extension in the Preference tab.

Reason 4. Autofill Data

Autofill is one of the handiest features especially when it comes to your passwords and phone number. But, if you have tons of data in your autofill, then there is a chance that your Safari might freeze up. For this, you can just simply turn it off or you can disable those that you do not need.

How to Remove Autofill History？

Here is how you can manage your autofill.

• Launch the Safari browser on your Mac.
• Then click on Preferences in the menu bar.
• Then choose the Autofill tab.

From the autofill tab, you will be able to disable any user for your Autofill. Just go ahead and click on the Edit button and you will be able to see all the data that is stored in your autofill. From there, just go ahead and delete the autofill that you no longer want and need.

Reason 5. You have Outdated Plugins like Java and Flash

As what we all know, several websites actually require you to have a Flash or Java on your Safari browser for you to be able to play videos or any animated content on the website that you are visiting.

However, once you have an outdated plugin on our Safari, then this could affect the performance of your browser.

How to Update Your Java and Flash Player？

Now, this is a very simple solution. Since you have an outdated Flash or Java, then all you need to do is to have it updated. For you update your Flash player to the most recent version, then the best way to do this is by going to the Adobe’s website.

This is because once you visited their site, it will immediately identify if you have an updated or an outdated version of your Flash player.

For you to be able to update your Java, just go ahead and go to the Oracle’s website. From there, you will be able to see if you have the updated version. If you do not have the updated version, then the website will give you instructions on what you should do.

Part 2. What Can You Do If Safari Slow to Load?

You may be so confused about the slow loading problem of Safari. Don't worry, you can check how to quickly and securely solve Safari slow to load below:

• Change your search setting.
• Change your network service order.
• Turn off your dashboard.

Change Your Search Setting

This is one of the things that you can try once that you are experiencing that Safari Slow to load. Here is how you can change your search settings.

• Launch Safari on your Mac and then go to the Preference tab.
• After that, click on the Search tab.
• Then, change your search engine into Bing.
• After changing your search engine, close Safari and launch it again.
• Check if there is any difference between its performance.
• After that, do the same steps and change your search engine into Google.
• Then, try to check it again.

Here, you can also uncheck all the options such as your search engine suggestions, Safari suggestions, quick website search and more. This is for you to be able to see any difference that will happen.

Change Your Network Service Order

If in case that you have a machine that is connected to your Wi-Fi and your Ethernet, then there is a possibility that the cause if you are connected to two different ways.

All you have to do here for you to check is go to your System Preference and then choose Networks. From there, go ahead and try to disconnect one of your network sources and try to run your Safari browser for you to see any difference.

Turn off Your Dashboard

If you are still using a 2010 Mac or earlier, then this could mean that you have a graphics card issue. Because of this, you can go ahead and try to use other things and see if it will help improve the performance of your Safari browser.

This is by disabling your Dashboard feature in your Mission Control Settings. For you to do this, just go ahead and launch your System Preferences. After that, go ahead and click on Mission Control. From the drop-down box located beside Dashboard, go ahead and toggle it off.

Part 3. In Conclusion

As you can see, there are many reasons as to why your safari running slow. Keep in mind that the Safari browser is just like those other browsers that you have installed in your Mac. It can also get stuffed. Besides that, you may also encounter Safari loading slow on your iPhone.

Once that a browser is full of all the activities that you made using your browser, then they are actually stored there and those will greatly affect the performance of your browser. Because of this, it is advisable for any Mac users to have a browser cleaner installed on their Mac to maintain the speed and high performance of the Safari browser so that you won't suffer Safari Slow to load.

Excelentes dicas. Melhorou o desempenho. Obrigado

Safari in my experience has intermittent issues affecting loading of web sites. Is it a compatibility issue or something on the web sites that doesn’t play nice with Safari? That is possible since many say other browsers are not affected. This would rule out the OS or hardware or network. But would place the focus on Safari as the issue. Since Safari is purely a Apple OS boy browser. It could be a case that Apple is not following certain standards or adopting them as other browsers have.

Ro Gal 2020-11-05 22:04:40

Tried all the 5 steps and more to no avail. This is a new Macbook Air w/plenty of juice and the latest updates. Safari is just too slow on many sites, so back to Chrome and Brave.

How Apple made Safari about 60% faster in the last 6 months

A month ago, we told you about the release of Speedometer 3.0 , a new web performance testing benchmark that aims to provide a more fair and representative measure of how a web browser performs at modern web tasks. Unlike earlier versions of Speedometer, which were made more or less by Apple’s WebKit team, version 3.0 is made in a collaboration between Apple, Google, Microsoft, and Mozilla with a new governance model to agree upon what tests are important representations of the modern web.

In other words, it’s probably the most “fair” and up-to-date measurement of web browser performance we have right now.

WebKit is the rendering engine used by Safari and provided to Apple developers who wish to use web rendering within their apps. It’s required to be used by every browser on iOS or iPadOS except for those inside the EU. Apple’s WebKit development team published a blog post detailing how they used Speedometer 3.0 as a guide to optimize performance from Safari 17 (released in September 2023) and Safari 17.4 (released in March 2024).

Over those six months, a lot of small incremental improvements made a big difference. As the blog post summarizes:

With all these optimizations and dozens more, we were able to improve the overall Speedometer 3.0 score by ~60% between Safari 17.0 and Safari 17.4. Even though individual progressions were often less than 1%, over time, they all stacked up together to make a big difference. Because some of these optimizations also benefited Speedometer 2.1, Safari 17.4 is also ~13% faster than Safari 17.0 on Speedometer 2.1.  WebKit blog post

Some of those improvements include things like batching compositing layer updates, increasing cache size on macOS, improving inline and SVG layout, and more. Many of these improvements are minor, resulting in just a few percentage points here or there, or targeting very specific parts of web performance. But multiple small improvements compounding over time made for a much faster browser.

This doesn’t mean Safari is much faster than other Mac browsers, though. When we tested Speedomenter 3.0 last month , we were running Safari 17.4 and found it to be the fastest browser but only by a very small margin. Edge still had some catching up to do, but Chrome and Firefox are both just behind Safari’s Speedometer score.

How to fix a slow or unresponsive mac.

Don't put up with an unresponsive Mac! We've got some things you can try to give your sluggish machine new life.

Is your Mac slow? Do you see the spinning pinwheel of death every day? Don't put up with it! Here's how to diagnose the issue so you can fix the problem.

How to Diagnose a Sluggish Mac

There are many reasons why your Mac might have performance issues. If you can figure out what's wrong, you can take steps to rectify it. You can fix most common causes of a slow Mac yourself, and relatively easily. Here are some of the easier  tips you can try to speed up your Mac .

Hardware issues, though, are the exception. If your Mac has a problem with a particular component, the fix becomes more complicated. Even desktop computers like the iMac are notoriously difficult to repair yourself---Apple uses heavy amounts of glue and solder in its manufacturing process.

In a worst-case scenario, you can always ask Apple to take a look. If you book a free Genius appointment at an Apple Store, they run a full set of diagnostics on your machine. From there, they should be able to recommend a fix for the problem. If you want Apple to repair your machine, you have to pay out of pocket if the warranty's expired, unless  you have AppleCare+ .

Save Money on Repairs with AKKO

When your device needs repairs, you can save money by investing in AKKO's low cost insurance coverage for all of your electronic devices at a fraction of the cost that you'd pay for AppleCare+.

Remember, it's free to book an appointment at an Apple Store, find out what's wrong with your machine, and how much it will cost to fix. The company only charges you for repairs after it has your consent to make them.

App Crashes: How Software Can Slow Down Your Mac

When software isn't working correctly, it can make your machine seem unresponsive. Sometimes, just the app that's crashed exhibits this behavior; other times, misbehaving software might attempt to take your whole machine down with it.

If you suspect an app crashed, right-click its icon in the Dock, hold the Option key on your keyboard, and then click Force Quit. You can also use the keyboard shortcut Command+Option+Esc to force quit the current app.

If you're not sure which app has crashed, or you think one crashed in the background, launch Activity Monitor. Click the "CPU" tab and view the "% CPU" column in descending order. This way, the apps using the most processing power appear at the top. If you spot anything using more than its fair share, click it, and then click the "X" to kill the process.

Sometimes, performance issues are caused by memory leaks, where a particular task or process eats up all the available memory. To see the memory, click the "Memory" tab, and reorder the "Memory" column in descending to see similar results. You can kill processes the same way you would an app that's crashed.

Processes that have completely crashed appear in red with the words "Not responding" next to them under Activity Monitor. You can kill these and restart them. If you encounter repeated issues with the same apps, you might want to consider using something else (or drop the developer an email).

Disk Space: Your Mac Needs Room to Breathe

Low disk space is another common cause of macOS slowdown. Without enough free space on your startup disk, macOS is unable to run maintenance scripts and background processes that keep your computer ticking along. Unfortunately, Apple doesn't specify exactly how much free space is required to keep your Mac happy.

A general rule of thumb is to keep 15 percent of your startup disk free at all times. This figure applies mostly to laptops with small drives. An iMac with a 3 TB drive requires a much smaller percentage to satisfy macOS requirements. But it's also much harder to fill up a 3 TB iMac than a 128 GB MacBook Air.

If you work with large files or create lots of temporary files (like for video or photo editing), you should keep as much free space on your drive as the total size of those temporary files.

To see how much free space you have on your Mac, click the Apple icon in the top-left corner, and then click About This Mac. Click the "Storage" tab to see a breakdown of your current disk usage. You can then  free up space on your Mac .

System Resources: Are You Pushing Your Mac Too Far?

Your Mac has a finite number of resources available, limited by factors like processor cores, available RAM, and the presence of a dedicated graphics card. If you know how far you can push your Mac, it will help you avoid performance issues in the future.

Some common tasks that might push your Mac over the edge are:

• Too many open tabs in your web browser.
• Hungry software, like Photoshop, open in the background.
• Playing graphically-intensive 3D games.
• Working with huge video and photo files or rendering video.
• Doing two or more of the above (or similarly intensive processes) simultaneously.

If you have hundreds of tabs open in a browser like Chrome, don't be surprised if you encounter memory issues. If you switch to a Mac-optimized browser like Safari, it will help, but you still might need to curb your tab addiction.

Browsers, in general, can be a source of poor performance. Too many extensions and plugins negatively affect your browser's responsiveness. And some web apps can tax your machine just as much as native ones. One example of this would be if you use a web-based spreadsheet tool, like Google Sheets, to crunch a lot of data.

To find out how your system is faring at any point, open Activity Monitor and check the "CPU Load" and "Memory Pressure" graphs on the CPU and Memory tabs, respectively.

Hardware Issues: Problems Under the Hood

Few computers hold resale value like a Mac. They're built to last, and I can say that because I'm typing this on 2012 MacBook Pro. But problems can arise---particularly if your machine is showing its age. But there are some things you can check yourself.

Apple Diagnostics

Your Mac includes a basic diagnostic tool you can run yourself. Follow these steps to do so:

• Shut down your Mac.
• Press the power button to turn on your Mac, and then immediately press and hold D on the keyboard.
• When you see the screen that asks you to select a language, release the D key.
• Select a language, and then wait for the diagnostic tool to run.

Note:  If Apple Diagnostics doesn't start, try holding Option+D instead. You need an internet connection to do this because your Mac downloads Apple Diagnostics before it runs it.

Apple Diagnostics can only tell you so much in the form of a reference code. You can then check the reference code in Apple's database , but don't expect to learn too much. For example, you might discover there's a problem with the computer's memory, but you won't know which stick of RAM is faulty or what's wrong with it.

This tool is useful to rule out hardware issues, but it's pretty useless for troubleshooting purposes. For a more detailed report, you're better off booking a free appointment at the Genius bar. Of course, you won't get detailed feedback about how to fix your Mac there, either.

You can check some components manually with the right tools. For example,  MemTest86  is a free tool you can use to check your computer's memory. Install it on a USB stick, start your Mac, and then run it. When you use a USB stick as the storage medium, you can test the RAM properly without the macOS overhead.

A failing drive can also cause issues. Most Macs have solid-state drives. These aren't prone to failing abruptly the way standard hard disk drives are. Solid-state drives generally only fail after some advance warning. And when they do eventually die, data recovery is impossible. Follow the steps below to check the health of your SSD:

• Click the Apple logo in the top-right corner, and then choose About This Mac.
• Click System Report, and then choose Storage.
• Select your main drive (likely labeled "Macintosh HD").
• Scroll down to "S.M.A.R.T. Status" and see what is written alongside it. If it says "Verified," your drive is performing normally, with no issues. If it says "Failing," this could be the source of your problems. Eventually, the drive will become "Fatal," and you'll have to replace it or your Mac.

For a more detailed look at your drives, download DriveDx (it's free to try). This utility should give you more information than Apple claims it will.

For ultimate peace of mind, be sure to  back up your Mac regularly with  Time Machine .

CPU & GPU

The CPU is the brain of your computer. There's not a lot you can do to test it, though. If it's not functioning correctly, you might encounter slowdowns, freezes, and sudden shutdowns. One way to glean more information is to benchmark it with an app like Geekbench . You can then use the Mac benchmark charts  to see how it stacks up.

If your Mac has a dedicated GPU, you can test it with tools like Heaven or Cinebench . If your GPU has issues, you might notice unsatisfactory performance in 3D applications, onscreen artifacts and glitches, system freezes, or sudden shutdowns.

Unfortunately, there's not a lot you can do to fix issues with the CPU or GPU. Any problems that arise there will likely require that you replace your Mac's logic board. It usually makes more financial sense to just buy a new Mac rather than pay the premium to fix your old one.

Decline with Age: Is Your Mac Just Old?

Sometimes, performance issues have a very simple cause: age. As your Mac ages, expect its performance to decline. New software requires better hardware, while the hardware inside your Mac stays the same.

Most Mac owners shouldn't encounter too many performance issues over the first three years or so of use. After that, things start to go downhill. Once you pass the five- or six-year mark, you're going to have to consistently think about whether the software you run gets the most out of your machine.

If you have an old Mac and you'd like to squeeze as much life out of it as possible, here are a few things you can try:

• Switch to a lightweight browser. Safari is optimized for Mac, and it tends to offer better performance and lower energy usage than its rivals.
• Favor Apple's first-party apps.  Like Safari, many Apple apps are optimized for macOS and Apple hardware. One striking example of this is Final Cut Pro, which drastically outperforms Adobe Premiere on older machines. You could also ditch Pages for Word, Lightroom for Aperture, or Evernote for Notes.
• Be mindful of multitasking. Avoid overstressing the CPU or GPU unnecessarily. If you're rendering a video, go make a cup of coffee until it's done. If you have 100 tabs open, close 50.
• Beware of outdated or sluggish software.  Outdated apps might perform worse on modern macOS systems because they lack optimization. Avoid using Java-based apps that require the Java Runtime Environment, as it can tax the performance of your machine.
• Keep macOS updated. Whenever possible, make sure your Mac is running the latest version of macOS. Apple focused on improving macOS performance over the last few iterations of its desktop and mobile operating systems. If your system isn't up-to-date, you might be missing tweaks that could improve your experience.

When Should You Buy a New Mac?

The right time to buy a new computer is when you need one. If you're encountering performance bottlenecks that prevent you from doing your job or doing the things you need a computer for, it's time to upgrade.

If your machine constantly crashes or is sluggish due to a failing hardware component, it's time to consider purchasing a new one. If you're sick of juggling files and apps because your startup disk is too small, you might want to stop by the Apple Store.

Remember, your old Mac might still hold good resale value. Even ancient machines with problems fetch more money than you would expect. If you're thinking about selling your old Mac, here are some tips to help you out .

3. Check and Reset Network

Sometimes Safari is slow to load may not be a problem inside Safari. The network condition is also a key to the speed of Safari.

You can check whether the network is disconnected and whether the internet signal is good. If you find that the network condition is bad, you can switch the network in time.

Here we also find a faster way to monitor the network speed for you - BuhoCleaner . It is a powerful network speed checker.

And here's how to use BuhoCleaner to monitor internet speed:

• Free Download , install, and launch BuhoCleaner.
• Click on the BuhoCleaner Menu, then select Preferences .
• Switch to the Status Menu tab and select the data you want to be displayed in the menu bar.

4. Update Safari

Outdated Safari may also be a possible cause for Safari running slow. So you need to update your Safari in time. The most up-to-date version of Safari is included with the latest version of macOS.

And here's how to update Safari:

• Click on the Apple menu , then select System Settings > General .
• Choose Software Update from the options.
• Click on Restart Now and wait for the update to finish.

5. Disable Unwanted Extensions

Installing multiple Safari extensions may lead to increasing CPU and RAM, which means the performance of the browser will be significantly slowed down. We recommend you uninstall some unimportant extensions to speed up Safari.

And here's how to disable unwanted Safari extensions:

• Click the Safari menu > Settings > Extensions .
• Find the extension you want to disable and click Uninstall , and wait for the uninstallation to finish.

6. Disable Search Engine Suggestions

Search engine suggestions are easy to ignore but disabling them also plays an important role in speeding up Safari.

Follow the steps below to disable search engine suggestions:

• Click the Safari menu > Settings＞Search.
• Uncheck Include search engine suggestions .

7. Disable DNS Prefetching and Switch DNS Provider

DNS prefetching is the act of resolving a website's IP address before a user clicks on its link. If you are running Safari version 5.0.1 or later, DNS prefetching will also slow down your Safari. So you need to disable DNS prefetching in time.

And here is how:

• Open Terminal .
• Enter the following text: defaults write com.apple.Safari WebKitDNSPrefetchingEnabled -boolean false .
• If you have Safari open, you will need to quit and relaunch Safari.

Switching DNS providers can also speed up Safari. Follow the steps below:

• Click the Apple menu > System Settings ＞ Network ＞ Wi-Fi ＞ Details ＞ DNS ＞ + .
• Enter 8.8.8.8 / 8.8.4.4 and click OK .

8. Check and Clear Virus

In addition to the above methods, checking for viruses is also a practical way to speed up Safari. If you have a virus on your computer, your Safari will obviously be affected. So you can download antivirus software and check for viruses.

9. Have a Thorough Cleaning for Your Mac

In addition, a slow Safari may need a thorough cleaning. Removing unwanted apps and disabling startup items contribute a lot to a high-speed Mac.

We recommend that you pick a professional third-party software like BuhoCleaner to do a big cleaning of your Mac. After that, you may get a high-speed Mac as well as a high-speed Safari like before. Free up your Mac and Safari with BuhoCleaner now!

In addition to the above 9 methods, you can also go to the Apple Community to find a solution. Many people are experiencing the same problem as you, and you can see how others have solved the Safari running slow on macOS Sonoma problem.

Besides, you can go to Apple Support to find help.

We hope at least one of the above methods helps you get out of your problem.

Safari running slow may be caused by many reasons. Pay more attention to the points we listed when you are using Safari in general. Use the methods mentioned above to speed up your Safari now!

what version of Safari is running on macOS Big Sur 11.7.10?

I currently have Big Sur v.11.5 on my 2020 macBook Air and have started having issues with my version of Safari (v.14.1.2) and would like to update Safari. 

Software update on my macBook offers an macOS update to Big Sur v.11.7.10 (as well as an update to Sonoma 14.4.1).

I’m not ready to try updating all the way to Sonoma, so I was hoping Big Sur 11.7.10 would be an easier update and include an update from my current Safari v.14.1.2.

Big Sur 11.7.10 includes Safari 16.6.1.

Personally, I would upgrade to Sonoma but you could also upgrade to Monterey or Ventura.

Monterey, Ventura and Sonoma all include the latest version of Safari, 17.4.1.

To upgrade, have a current backup (a good idea even when not upgrading) and see:

Thank you. I’m a bit nervous about updating all the way to Sonoma 14.1.2 from Big Sur 11.5. Is that typically the best way to do it, rather than updating a little at a time?

I’m afraid something will stop working.

I normally update/upgrade as soon as the new version is available but you shouldn't have any issue updating directly to Sonoma. As stated in my previous reply you can also upgrade to Monterey or Ventura.

Either way you choose to do it, you should have a backup first (a good idea at all times).
