Best Ways to Speed Up Big Sur

Do you feel that your Mac has become slower after the Big Sur upgrade? Bring it back to speed with our comprehensive guide.

Big Sur, the newest macOS version, is studded with features aimed at enhancing user experience. Despite this, many users are yet to befriend their Macs with Big Sur, reporting a wide range of problems, slowness being the most common one. If you've run into this problem, too, we go over ways to inject some speed into Big Sur in this post.

Quit Unneeded Applications

Macs can get slow for many reasons, and resource-heavy applications being the most common one. You can locate and shut down resource-consuming processes using Activity Monitor. To do that, go to Finder on your Dock - Applications - Utilities - Activity Monitor. Then switch to the CPU tab and sort the processes by their CPU consumption. To shut down the most resource-consuming ones, pick the process and click Quit.

Ban Startup Apps

Another way to speed up Big Sur is disabling the apps that launch by default as you boot up your Mac. Running in the background, they put a lot of pressure on your RAM and CPU. You can spot such apps and stop them by going: Apple Menu - System Preferences - Users & Groups. At this point, you should choose your current account and enter your password. After that, switch to the Login Items tab, where you'll find all apps that accompany the Big Sur startup. Click on the Minus sign to disable them.

Clear Cache Data

Cache data is temporary data generated by the system, applications, or browser. If the cache storage runs out of space, it may affect your Mac's speed. You can remove the system cache by selecting Go in the menu bar, then pick Go to Folder and enter /Library/Caches in the search field. Then you should click Go, choose files in the folder that has your cached data and select "Move to Trash." That's how you do away with the system cache. Check this post for a detailed guide on how to remove other types of cache.

Update Big Sur

Apple releases Big Sur updates regularly. The updates patch security holes and fix different flaws that can improve your Mac's speed. Thus, installing the most recent OS version can be the key to speeding up Big Sur. To check for an available update, go to the Apple menu - System Preferences - Software Update. If you find a pending update, click on Update Now.

Update Your Apps

Although the Apple team is improving the compatibility of the apps with Big Sur, some apps are yet to make peace with the new OS. Thus, chances are your apps have become incompatible after you've upgraded to Big Sur. You can fix this by running updates of the apps on your Mac. For Apple's native apps (the ones you've downloaded from the Mac App Store), go to the Store, check available updates and install them. For the rest of your apps, check for available updates from their providers.

Reset SMC

If the ways described above didn't work, you can try resetting System Management Controller, as the problem may lie more deeply in the system. SMC is responsible for essentials like the battery, light sensing, cooling system, and more. Although it's not commonplace, the problem with SMC may affect your Mac's performance. The methods of resetting this parameter depend on your Mac's model and whether it comes with a removable battery.

Reinstall Big Sur

Finally, you can reinstall the new macOS if nothing else has improved its speed. Note that re-installation will wipe all data from your current Big Sur version. As such, you should take care of backing your files up using multiple options, ranging from iCloud and Time Machine to external disks. To reinstall Big Sur, you can do the following:

  • Enter the Recovery Mode: Hold down the power button and switch off your Mac;
  • Press and hold down Command + R and then press the power button;
  • That'll take you to the Utility screen;
  • Release the buttons;
  • Pick "Reinstall macOS".

This way, you download the most recent Big Sur installation version, which will automatically install on top of your current version.
