6 Best Ways to Fix Safari High Memory Usage on Mac

While Safari is one of the fastest and most-efficient web browsers on Mac, it isn’t void of issues. Sometime Safari keeps crashing on Mac , fails to find the server , and consumes abnormal memory usage. Such behavior raises the Mac temperature and slows down the system. Here are the best ways to fix Safari’s high memory usage on Mac.

High memory usage by Safari also leads to glitches and errors in other apps. Since your Mac apps have less RAM, you need help with day-to-day operations. We will first show you how to confirm Safari’s high memory usage and go through troubleshooting steps to fix the problem.

Use Activity Monitor to Confirm High Memory Usage

Before making any changes to the Safari browser on Mac, you’ll need to confirm the default browser’s rogue behavior. We will use the built-in Activity Monitor in macOS. Follow the steps below.

Step 1: Press the Command + Space keys shortcut to open the Spotlight Search.

Step 2: Type Activity Monitor and hit Return.

Step 3: Move to the Memory tab.

Step 4: You can check memory pressure, total physical memory, used memory, cached files, and swapped memory.

Step 5: Check Safari under the Process Name and see how much memory it consumes.

Usually, 2GB-3GB memory usage is normal behavior from a desktop browser. If you notice Safari taking up 8GB-9GB RAM, it’s an alarming situation, and you need to fix it to keep your Mac running smoothly.

1. Close Irrelevant Tabs

Safari doesn’t come with something like Sleeping tabs (Microsoft Edge) or Memory Saver (Google Chrome) to put irrelevant tabs to sleep and preserve memory. The browser keeps all the tabs actively running in the background all the time. You need to close unnecessary tabs frequently to prevent high memory usage on Mac.

Step 1: Open Safari on Mac.

Step 2: Glance over all the opened tabs at the top.

Step 3: Hit the ‘x’ mark beside the tabs you don’t want to use right now.

If you plan to revisit the same article later, Bookmark it or add it to your Reading List.

Step 4: Click the small ‘+’ icon in the address bar and add the webpage to Reading List.

Step 5: Right-click on the same ‘+’ icon to Bookmark the page.

2. Review Safari Extensions

Safari supports third-party web extensions to improve your browsing experience. The selection is slim compared to Chrome Web Store, but it still boasts many extensions.

Not every extension is regularly mainlined and updated. If you have several outdated, unnecessary extensions running in the background, it may consume high memory usage. You should review the installed Safari extension and uninstall irrelevant ones.

Step 1: Launch Safari on Mac.

Step 2: Select Safari in the top-right corner of the menu bar and select Settings.

Step 3: Click on the Extensions tab. Select unknown extensions from the left sidebar.

Step 4: Hit Uninstall and confirm your decision.

3. Force Stop Safari

Due to high memory usage, Safari may become unresponsive at times. You should force-stop Safari and try using it again.

Step 1: Launch Activity Monitor on Mac (refer to the steps above).

Step 2: Select Safari and hit the x mark at the top.

Step 3: Relaunch Safari and keep a close eye on memory usage.

4. Simplify Safari Homepage

Safari lets you customize the homepage with useful add-ons. But when you jam your homepage with Siri suggestions, Privacy Report, background images, and other menus, it may consume high memory usage. Here’s how you can simplify the Safari homepage on Mac.

Step 1: Open Safari and select the customize button in the bottom right corner.

Step 2: Disable the checkmark beside irrelevant menus and launch the app again.

5. Update macOS

Safari is closely tied to macOS. Apple releases new Safari features and bug fixes with new macOS updates. An outdated macOS build may lead to high memory usage in Safari.

Step 1: Click the Apple icon in the top left corner and open System Settings.

Step 2: Select General and open the Software Update menu.

Step 3: Download and install the latest macOS update.

6. Ditch Safari in Favor of Microsoft Edge

If you are still facing issues with Safari, it’s time to ditch Safari in favor of other alternatives. The Mac ecosystem is packed with many capable browsers, and Microsoft Edge is one of the best among them. It has a long feature list, is compatible with all Chromium browsers, and works on all platforms.

How to fix "this website is using significant memory" on a mac.

What do you do when Safari tells you a website is hogging more than its fair share?

Quick Links

What the "significant memory" warning really means, things you can try that may help, ditch plugins and extensions to speed up safari.

Your Mac only has a finite amount of memory available, so if a process starts to use more than its fair share, the rest of the system can suffer. Sometimes, Safari will warn you that a website is using a lot of memory, but what can you do about it and how do you stop it from coming back?

Your computer uses physical memory, or RAM (random access memory), to store data that needs to be rapidly accessed by the system. The more memory you have, the longer you can go before running out. To make the most of available memory, the solid-state drive is used as a temporary location to " swap " data in and out as required, which is why a Mac with twice as much memory isn't necessarily twice as capable.

Some websites require more system resources than others. This is often the case with complex websites like social media feeds or web applications like Google Docs which handle a lot of data. There also may be scripts running in the background of a webpage that introduce additional overhead.

The "significant memory" warning is an indicator that a tab is asking for a lot of system resources, which may lead to a performance drop. More memory being used by one process means there is less memory available to the system overall. This can result in slowdowns, crashes, and instability.

This warning will only appear above the tab causing the issue, so you may need to cycle through tabs if you suspect a web page is causing your computer to perform poorly.

The easiest remedy is to refresh the tab in question. This should force Safari to reallocate resources, freeing up any memory that's tied down and removing the warning. Unfortunately, a problematic website is likely to keep asking for more resources and so the warning can come back.

Safari splits tabs up by process in Activity Monitor (accessible via Spotlight or under Applications > Utilities). Access the "Memory" tab then arrange the "Memory" column by descending to see which processes are using the most memory at the top. You can quit any webpage process to force a reload.

You can take the more drastic route of quitting Safari altogether (using Command+Q or simply right-clicking on the dock in the icon). If Safari has become unresponsive you may need to force quit the process to restore performance.

Sometimes warnings such as these can be caused by problems rendering a webpage as a result of an outdated browser. Install any available updates for Safari under System Preferences > Software Update is recommended for both  performance and security reasons .

If the website in question has an issue with Safari in particular, installing and using a second browser like Chrome or Firefox  could be the answer. Safari is a solid choice for Mac users on account of being highly optimized, but it often doesn't enjoy the same support as more popular cross-platform browsers.

If you're seeing this error a lot, you might want to consider upgrading your Mac . If your machine is relatively new, it's likely a problem with the website and you may want to submit a support ticket or seek an alternative. Accessing the website periodically rather than leaving it open all of the time could work too.

Webpages using more than their fair share of resources is an issue that appears from time to time, but there may be more you can do to improve Safari's performance across all websites.

Consider ditching web plugins and removing unnecessary browser extensions  to reduce Safari's overall footprint, freeing up more resources for thirsty webpages and other processes.

6 Fixes for Safari Using Too Much Memory on Your Mac

Safari is notorious for consuming too much memory, but here's what you can do to lower its memory usage on your Mac.

Most Mac users prefer Safari to other browsers. It's lightweight, fast, secure, and gives you access to many ecosystem features, which can come in handy if you also have an iPhone or iPad.

That said, Safari has its fair share of problems; one of them is high memory usage. Although the browser isn't heavy on resources, certain factors can cause it to consume too much memory on your Mac.

But fret not, as it's pretty easy to fix this problem. So, try the fixes below to lower Safari's memory usage on your Mac.

1. Close Tabs You Don't Need Anymore

At times, while looking up something on the internet, we end up opening multiple tabs in the browser and forget about closing the ones that are no longer required. This results in websites—open in those tabs—hogging up resources while trying to load and display their content, which, in turn, stresses the memory.

Hence, the first step toward fixing Safari's high memory usage on your Mac is to close the tabs you no longer need. Simply hover over the tab you want to close and click the close (X) button to the left of the tab.

Now, you can launch Activity Monitor using Spotlight search ( Cmd + Space ) and check the memory consumption. If it's still high, it could be because there's still a website open in Safari that's eating up memory. Bookmark all your open tabs in Safari and then close them one by one to identify this website.

2. Clean Up the Safari Start Page

Much like irrelevant tabs, having too many add-ons on the start page can also cause Safari to keep your Mac's memory engaged. As such, removing the add-ons you don't use can help free up some memory on your Mac.

By default, Safari displays all add-ons on the start page. But you can customize the start page in Safari to choose which add-ons are displayed based on your preference.

To do this, open Safari and go to the start page. Click the Customize button in the bottom-right corner of the screen and uncheck the checkboxes next to the add-ons you don't use.

3. Disable Unused Safari Extensions

Extensions allow you to personalize your browsing experience in Safari and enhance the browser's functionality. But sometimes, these extensions do more harm than good.

Excessive memory usage is a common problem many Mac users complain about with certain Safari extensions , like Grammarly, for instance. So, if the above fixes don't resolve your problem yet, reviewing the installed extensions can help you find the culprit that may be hogging your Mac's memory.

An easy way to do this is to look carefully at memory consumption by various Safari extensions in the Activity Monitor app. Simply search for Safari in the search bar, and it'll return all the extensions and their current memory usage.

Once you've identified the rogue extension, you can disable or delete it to free up some memory. Here's how:

• Go to Safari > Settings from the menu bar.
• To disable an extension, uncheck the checkbox next to it. Alternatively, if you wish to uninstall the extension, click the Uninstall button.

Some extensions may be part of an application, so you'll need to uninstall the associated apps to remove them. So, when Safari prompts you about the same, click the Show in Finder button to find the associated app in Finder, and then Control -click on it and select Move to Bin to uninstall it.

4. Clear Safari's Cache

Safari stores temporary files in the cache to load pages faster and improve overall usability. However, as you use it over time, it ends up accumulating a lot of files, which can affect the browser's functionality.

Clearing the cache from time to time fixes this problem. To do this, first, enable the Develop menu by opening Safari Settings , going into the Advanced tab, and checking the box next to Show Develop menu in menu bar .

After this, click on Develop in the menu bar and select Empty Caches .

Once you do this, you may notice certain pages taking longer to load. This is because the browser doesn't have the cached files to pull up the webpage. But it's a small compromise to bring down Safari's memory usage.

5. Force Quit Safari

If high memory usage is making Safari lag or unresponsive on your Mac, try closing it. First, bookmark all the open tabs so you don't lose anything important. After this, click Safari in the menu bar and select Quit Safari .

In most cases, this should do the job. But if this doesn't quit Safari, you'll need to force quit the app. Control -click the Safari icon on the Dock and hold down the Option key to see Force Quit in the context menu.,

6. Update Your Mac

If none of the fixes listed so far work, there could be a problem with Safari or some related service that may be causing it to consume too much memory. Updating your Mac or Safari is the way forward in this case.

Apple releases updates for both Safari and macOS from time to time. And when you install a macOS update, it automatically updates Safari to the latest version. But if you don't wish to update macOS for some reason, you can install just the Safari update.

To update macOS, open System Settings and go to General > Software Update . Let the Mac check for a new update. If a new macOS version is available, click the Update Now button and follow the on-screen instructions to install the update.

On the other hand, if you just want to update Safari, click on the More Info button in the Updates Available section and uncheck all the boxes except Safari. Once done, click Install, and it'll update the Safari browser on your Mac.

Reduce Excessive Memory Usage and Make Safari Faster Again

Although Safari usually runs smoothly on a Mac, it can sometimes exhibit excessive memory usage. Following the fixes above should help you lower its memory usage and bring it to a normal state. Alternatively, you can check out Safari alternatives and perhaps eventually switch to a new browser if you like it better.

How can I limit Safari's RAM use?

Safari uses a lot of RAM. Especially when you add Safari's use to WebProcess's use: it comes to about 1.5 GB of memory (for me, anyway). How can I limit the amount of RAM Safari and WebProcess use?

I know a similar question was asked last summer, but two of those answers have to do with the program in question (Dropbox) and the other answer encourages use of Terminal, which I find terribly confusing. Are there any other methods?

• memory-limit

• Frustrated by the same problem, except with 3-4 GB rather than 1.5, I made the switch to Google Chrome a few months ago. I've long used Chrome on Windows, but preferred the native platform experience of Safari on OS X. Chrome's gotten very good at acting like a native app, and I've been happy with it. Subjectively, the UI feels more responsive than Safari, and they share the awesome WebKit rendering agent. Most importantly, I've had no trouble with memory leaks or freeze-ups. I hate restarting my browser, and I regularly leave tabs open for weeks. –  Cody Gray - on strike Apr 5, 2012 at 22:07
• @CodyGray I've actually migrated to Safari from Google Chrome—I don't have Flash installed except for Chrome's version, which saves system resources in general. When I want to use Flash, I just open it in Chrome! –  Tuesday Apr 5, 2012 at 22:20

Safari's excessive RAM usage limiting

By default, new windows and tabs in Safari are displayed in “Top Sites”, a 3×4 grid displaying those web sites visited most often with Safari.

'Top Sites' makes for a cute home page, but it will show sites one doesn't want showing up, and it will slow down Safari, especially on older computers. This ostensibly useful feature is loathed by quite a few users because it slows down Safari and the system.

While there is no easy and 100% safe way to turn 'TOP SITES' totally OFF, a few steps listed below will help Safari's performance and lessen excessive RAM use:

Stop Safari slowing and consuming extra RAM (as it visits all the websites listed in Top Sites) by removing any and all webpages from Safari's 'Favorites Bar' periodically (every week or so): Preferably, delete all webpages displayed within 'Top Sites':- Safari > History > Show Top Sites —> mouse-over each page (not regularly visited) so that the 'Delete-X' appears in the top-right corner, and click the 'X' — keep the iCloud page and the selected search engine for Safari, preferably Blekko (alt., DuckDuckGo, &c), if and only if regularly visited. Alternative method of deleting all the webpages within 'Top Sites':- Safari > Edit Bookmarks > Favorites Bar —> highlight all bookmarks and folders —> Edit > Delete.

In this way, Safari's WebProcess component (an integral part of Safari's Sandboxing functionality) won't keep pinging those sites to download data (just to provide Previews of those sites); it's a known bug - missing parts of PerformanceNavigation & PerformanceTiming in the WebKit2 component of WebProcess used by Safari.

• By how much did removing Top Sites reduce Safari memory usage? Safari is a memory hog for tons of reasons, and this is only one, and I suspect not a very major one. –  smci Oct 14, 2015 at 1:11
• And why would removing sites from the Favorites Bar change anything at all? Does WebProcess actually ping them? –  smci Oct 14, 2015 at 1:11

Safari web content high cpu and memory usage on macos [solved].

Safari has become fucking pain in the ass recently. I’m not sure what caused it to get fucked. Safari Web Content process has been eating up more than 100% of CPU and over 2 GB of Memory.

I’m seeing this issue on both iMac and MacBook. I’ve macOS Big Sur on both machines.

Till now I haven’t found a solution so far. Below are some of the solutions which I’ve tried so far and none worked.

The Solution Which Worked For Me

I upgraded OS to macOS Monterey and this problem was gone. I’m still observing though.

Other Solutions Which You Can Try

Low ram/memory.

The first culprit which anyone would point is low RAM. I’ve fucking 32GB of RAM on my iMac so it doesn’t solve problem. Try adding more RAM if you could, it will certainly improve performance but it will not solve the underlying issue.

Disable Safari Extensions

Another common culprit for Safari or any browser could be extension/plugins. I don’t have any plugin installed so this solution isn’t applicable to me. If you have any extension installed in Safari then you can disable/remove them and try.

To disable/remove extensions go to Safari -> Preferences -> Extensions and disable/remove extensions and try.

Disable Develop Menu

Being a developer having Develop menu showing up all the time is a requirement for us. Some folks have suggested that disabling Develop menu may solve the issue but for me it also didn’t work.

To disable Develop menu go to Safari -> Preferences -> Advanced and uncheck Show Develop menu in menu bar .

Clear Cache

To clear cache you need to enable Develop menu again. From Develop menu click on Empty Caches. For me this solution also didn’t work.

Remember the fucking Windows PCs where the most obvious solution to all problems was to reboot PC? Try doing the same, sometimes it may work. For me this magic also didn’t work in fixing the issue.

Log out of Google Account

Some have suggested that logging out from Google account fixes the issue but that’s not true. In my case Safari Web Content keeps eating CPU and Memory even when I haven’t opened Google pages. Logging out also didn’t resolve the issue.

Quit All Apps

I’m in the habit of keeping plenty of apps and tabs in these apps opened. Quitting all apps doesn’t resolve the issue as it has nothing to do with anything else than Safari itself.

Just don’t use safari 😉

Avoidance is not a solution. For my day to day work I need to keep as many browsers as possible including Safari so just not using Safari is not a practical solution for me. Thanks for the tip though 😉

OMG! upgrading worked for me. Thank you so much for posting this article. I wasted whole day fixing this.

Found link to this post on reddit, upgrading to Monterey fixed issue for me too.

Upgrading OS fixed issue for me too. Do you know how it got fixed in Monterey?

No fucking clue. It just works. Most of annoying problems faced on macOS are resolved by upgrading OS.

Life saver, thank you!

Ajay, you saved my day. It has been freaking me out for past few months. I just upgraded to macOS Monterey and issue was gone. Safari doesn’t fry up my CPU and memory anymore. Thanks a bunch.

Easily Identify the Tab That Cause High CPU Load in Safari

Safari is the default, and believe it or not, the most commonly used Web browser in OS X system. And while it is a fairly robust browsing solution for Mac users, it can encounter periodic problems that can lead to high CPU usage or a hang, or other odd behaviour which may be difficult and frustrating to manage.

With the latest versions of Safari, your loaded Web pages are collected in groups of separate running processes. This helps keeps other Web pages stable if one goes awry. Here is a quick way to identify which tab/URL is causing the problem.

1. Load up Activity Monitor and search for “Safari Web Content”. Sort the item by CPU usage or any other method for locating the web page that is giving you problems.

2. Once you have located the problematic process, simply hover your mouse over it and you will see a tooltip box containing the URL of the page. Unfortunately you cannot click the links in Activity Monitor to bring the corresponding window to the front, but what you can do is use the link information to identify the potential Safari tab(s) that contain the problem. All you need to do is to review your windows, and see which contains tabs for the links in the tooltip. Once done, you can try to manage it without quitting and relaunching Safari, or more intrusive troubleshooting steps.

While this tip is useful for Safari, it should work for other processes that use WebKit, including “Content” processes for the App Store, though these may be more limited in scope (as in, the URLs of the App Store only) and not as useful for troubleshooting.

Macrumors 68020.

• May 13, 2022

Computer: iMac 24" mid tier model from Apple (8-core CPU/GPU and 8gb ram). Verizon 1GB fiber internet (700mb down to iMac via WiFI). OS/Software: Lastest Monterey with no other apps running in the background and adblockers off. I restarted Activity Monitor for each test. Websites Tested: MacRumors, YouTube, and Twitch As you can see just having the website of MacRumors loaded there's very little difference between the two if you add up all the Chrome processes vs Safari. I found that the majority of websites had similar resource usage so unless you have compatibility issues utilization is similar. However, when doing playback of media sites such as Twitch that's when things go off the rails. As you can see in the Safari Activity Monitor for Twitch it was maybe on for 5min and hit 1GB and would climb as much as possible if I let it keep going. Additionally, in Safari when having Twitch open and swapping to another tab Twitch routinely downgrades the quality (Chrome does as well) until you make that tab active again then the quality returns but Safari stumbles with this so you have to either refresh or manually set the quality. Using Chrome, I actually got distracted and let it run for longer and as you can tell it was as cool as a cucumber. I tested YouTube and on Safari it has some issues and even drops out of HD randomly but Chrome, as expected worked great but ya know...it's Google so to be expected. TLDR: On Apple Silicon Chrome is close and in some cases better with memory utilization over Safari currently so I feel it's time to at least be open on changing our mindset when it comes to the "Chrome is a memory hog" topic. Now on Intel chips it was bad and maybe it still is but for those with current Apple SoC test it for yourself.

Sorry, but I can't replicate what you're claiming. I just had 5 or 6 tabs open in Safari, running a Twitch stream for about half an hour and memory usage for Twitch fluctuated between 600MB and 1,1GB (but never went higher).

AltecX said: WHY does the architecture? You gave me no reason WHY. I literally use twitch for HOURS(3+ on average) sometimes all day long and have never had Safari use up all my memory.

Sheepish-Lord said: Do you have your Twitch video quality set to auto? If you do then once you tab out or if Safari detects high utilization it will throttle the quality. If you force 1080p on Twitch memory utilization will definitely go higher. I have a new MBP 16” it does this on as well. Try those settings for 15-20 min and use activity monitor. Click to expand...

I don't know... you work for Google or something? Been testing three browsers routinely: Safari, Chrome and MS Edge. Now, for work purposes I use Chrome, we live unfortunately in Google Workspace world. But for personal use, I always found that Chrome uses the most memory, Edge using less and Safari even less but not far behind Edge. Same tabs open, same stuff happening. When it comes to resources, Safari unfortunately always wins, and I say unfortunately, because MS Edge is actually a better browser.

I am not understanding this post 1. If those are the only applications open (Safari and Chrome)? It looks like there's another program, "magnet" running as well. 2. How much memory exactly is Safari using, and Chrome using. 3. Was it on a resent re-start or did you have the computer running for a while? 4. I'm not seeing what's wrong with high memory usage?

There is no high memory usage, the point of this thread was to talk about how Chrome/Chromium based browsers have a stigma about being memory hogs vs Safari when this not the case with Apple Silicon. The high memory usage was about Twitch and other people made it a big deal but was never the basis for this thread. Basically, it was to show folks all browsers are pretty much the same with resource utilization on Apple Silicon. Click to expand...

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.
