How to Manually Clean Up Your Mac

If you're a seasoned Mac user, you can clean up your Mac manually. Here are 9 ways you can try.

Optimize Mac Storage

As time goes by, more and more files accumulate on your Mac, taking up a lot of storage space. But don't worry, Mac has built-in optimization tools that allow you to optimize your storage space automatically.

  1. Click the Apple icon in the menu bar and select About this Mac.

Clean Cache Files

Caches are temporary files that speed things up on your Mac. They can accumulate and eat up your space if you don't clean them often. Common caches include system cache, application cache, and browser cache.

You can clear them one by one manually or let BuhoCleaner scan and delete them for you quickly. Either way will help you clear your cache and free up some storage space.

Delete Unused Apps

Another tip for cleaning up your Mac is to delete the apps you don't use. They take up your space for nothing. Therefore, it is a good idea to remove them completely from your Mac.

There are two ways to uninstall unnecessary applications. One is to drag them to the Trash, and the other is to use an application uninstaller like BuhoCleaner. We prefer the latter because it completely deletes the application and its related files. The former only removes the application itself, and the related files of the application still reside on your hard drive. We also have an article about How to Remove Leftovers on Mac.

  2. Launch it and click the App Uninstall tab.
  3. Click the scan button, and it will find all the apps uninstalled on your Mac.
  4. Find the apps you want to get rid of, select them and click the Remove button.

Clear Download Folder

You might be surprised how many useless files are in your Download folder. Clearing them can help you reclaim some storage space.

Clearn Your Downloads Folder

You can go to Finder and delete them manually. Or you can use a third-party finder tool, such as BuhoCleaner, to clean them up for you automatically. The former is time-consuming and suitable for experienced Mac users, while the latter is super easy and novice-friendly. We recommend you to use the latter. Click here to download it for free.

  1. For macOS versions before 10.15, you can go to iTunes > Preferences > Devices > Delete Backups.

Declutter Your Desktop

If you constantly put files, photos and screenshots on your desktop, chances are your Mac will look cluttered. And a cluttered desktop can not only bore you, but it can also make it harder to find your files.

The Mac has long thought of this problem. It has a handy tool built in that keeps your files neatly organized in groups. All you have to do is click anywhere on your desktop and choose Use Stacks.


Empty the Trash

The last and most important one is to empty your Trash. Why? Because we usually just move files to the Trash without cleaning them out of the Trash, and they still stay on your hard drive. Why not take a second to clean it up and then free up a lot of free disk space?

Update Your macOS

Updating your macOS can help you fix some problems with Mac and may make your Mac run faster.

If you downloaded the latest macOS version but didn't install it, it could take up a lot of your storage space. You'd better update your macOS now.
