Chrome Slower After macOS Update Fix

If Chrome feels slower after updating macOS, you are not imagining it. Many Mac users experience this frustrating issue, especially those with older machines or limited RAM. The good news is that there are practical steps you can take to restore Chrome’s speed and get back to browsing smoothly.

Why Does Chrome Slow Down After macOS Updates?

When Apple releases a macOS update, it often changes how the system manages memory, graphics, and background processes. These changes can affect how Chrome interacts with your Mac, sometimes causing Chrome to use more memory or run less efficiently than before.

On Macs with 8GB of RAM or less, this effect is even more noticeable. Older MacBooks and i Macs that worked fine before the update may suddenly feel sluggish. The browser may take longer to open new tabs, pages may load more slowly, and you might see the rainbow spinner more often than you would like.

Understanding why this happens is the first step toward fixing it. The issue usually stems from one or more of the following: increased memory usage, outdated Chrome version, conflicting extensions, or changes in how macOS handles background apps.

Step-by-Step Solutions to Fix Chrome After macOS Update

Update Chrome to the Latest Version

The first and most important step is making sure you are running the latest version of Chrome. Google regularly releases updates that improve performance and fix compatibility issues with new operating system versions.

To check for updates in Chrome, click on the three dots in the top right corner of your browser window, then go to Help and select About Google Chrome. Chrome will automatically check for updates and install them if available. After updating, restart Chrome and see if the performance has improved.

Keeping Chrome updated ensures you have the latest optimizations and security patches, which can make a noticeable difference in how smoothly the browser runs on your Mac.

Enable Chrome’s Memory Saver Feature

Chrome includes a built-in feature called Memory Saver that helps manage RAM usage more effectively. When enabled, Chrome automatically unloads tabs you have not used recently, freeing up memory for other tasks.

To turn on Memory Saver, open Chrome and go to Settings. Look for the Performance section in the left sidebar. Click on it and toggle Memory Saver to ON. You can also customize which sites should always stay active, so important pages like your email or work dashboard remain ready to use.

This feature is especially helpful for Macs with limited RAM because it prevents Chrome from consuming all your available memory just to keep dozens of tabs open in the background.

Disable Unnecessary Extensions

Extensions are one of the biggest causes of slow Chrome performance. Each extension you install adds code that runs in the background, consuming memory and processing power. After a macOS update, some extensions may not work correctly or may conflict with the new system, making the problem worse.

Take a few minutes to review your extensions by clicking on the puzzle piece icon in Chrome’s toolbar and selecting Manage Extensions. Remove any extensions you have not used in the past month. For extensions you need, make sure they are from trusted developers and up to date.

If you find that you need many extensions for your workflow, consider using Tab Suspender Pro, a Chrome extension specifically designed to help manage tabs efficiently. Tab Suspender Pro automatically suspends inactive tabs to free up memory while keeping your workflow organized. This is particularly useful for users with limited RAM who tend to keep many tabs open at once.

Clear Chrome’s Cache and Data

Over time, Chrome stores cached files, cookies, and other data to speed up browsing. However, after a macOS update, this cached data can become corrupted or outdated, causing Chrome to run slower.

To clear the cache, go to Settings in Chrome, then click on Privacy and Security in the left sidebar. Click on Clear Browsing Data. SelectCached images and files and any other data you want to remove, then click Clear Data. This can help Chrome feel snappier, especially if it has been a while since you last cleared these files.

Reset Chrome Settings

If the above steps do not resolve the issue, resetting Chrome to its default settings can help. This removes custom settings, extensions, and stored data that might be causing problems after the macOS update.

To reset Chrome, go to Settings, then click on Advanced at the bottom of the page. Look for the option to Reset Settings to their original defaults. After resetting, you will need to re-sign into your accounts and reinstall any extensions you need, but this often resolves persistent performance issues.

Additional Tips for Older Macs

Beyond the steps above, there are other things you can do to improve Chrome’s performance on older hardware.

Reduce the Number of Open Tabs

This is one of the most effective things you can do. Each open tab uses memory, and on a Mac with limited RAM, having too many tabs open can dramatically slow down your browser. Try to keep only the tabs you need open at any given time. Use bookmarks or a tab management extension to save tabs for later rather than leaving them open.

Use Chrome’s Task Manager

Chrome has a built-in Task Manager that shows you how much memory each tab and extension is using. To access it, press Shift + Escape on your keyboard while Chrome is open. This will show you a list of all open tabs and extensions along with their memory usage. Use this information to identify which tabs or extensions are using the most resources and close or disable them as needed.

Restart Chrome Regularly

If you use Chrome for extended periods without restarting, memory usage can build up over time. Closing and reopening Chrome once a day or when you notice it slowing down can help keep it running smoothly.

Consider Your macOS Settings

Sometimes the issue is not just Chrome but how macOS is managing resources. In System Settings, go to General and then About to check how much memory your Mac has. You can also check Activity Monitor to see which apps are using the most memory and CPU. If other apps are consuming too many resources, closing them can help Chrome run better.

When to Consider Alternative Solutions

If you have tried all these steps and Chrome still feels slow, you might want to consider using a lighter browser for everyday tasks. Browsers like Firefox or Brave are designed to use less memory and might run better on older Macs with limited RAM. You can still keep Chrome installed for specific tasks that require it, while using a lighter browser for general browsing.

Another option is to consider upgrading your Mac’s RAM if possible. Many older Macs can have their RAM upgraded, which can make a significant difference in overall performance.

Getting Back to Smooth Browsing

Chrome slowing down after a macOS update is a common problem, but it is one you can solve. By keeping Chrome updated, enabling Memory Saver, managing your extensions, and following the other tips in this guide, you can restore your browser’s performance and get back to browsing without frustration.

Remember, if you tend to keep many tabs open, Tab Suspender Pro can be a valuable tool for managing your tabs efficiently and freeing up memory. Combined with the steps above, these solutions can make a real difference, especially on Macs with limited RAM.
