What Is 'Other' on Mac Storage and How to Delete It

What is 'Other' in Mac Storage

System files and files that the system cannot recognize will be labeled as "Other." Here are some things that may be included in other storage.

  • macOS system and temporary files.
  • PDF, .psd, .doc and other files.
  • Cache files, such as user cache, browser cache, and system cache.
  • Installer packages, such as .dmg and .pkg files.
  • Browser plugins and App extensions.
  • All other content that does not fall into the main macOS category.

How to Check the Other Storage on Mac

Apple has made some changes to the storage category in a recent update to macOS Monterey. On the new operating system, there is no more Other storage. However, if you're using macOS Big Sur or an earlier version, the Other storage is still there. You can check it by following these steps.

  1. Click the Apple Menu > About This Mac > Storage.
  2. After the storage calculation is complete, you will see that your storage space is divided into several different colored sections, including Apps, Documents, Movies, Photos, System, Other, and more. Check Other Storage on Mac

Can I Delete the Mac Other Storage

Yes, but be careful. Things like .dmg files and leftovers from uninstalled apps are safe to clear. However, when deleting cache files, especially those in the system, you should be careful because you don't know what impact your macOS will have if you delete them by mistake.

As a rule of thumb, if you don't know what the file is or what it does, leave it be. In addition, it is strongly recommended that you make a full backup of your system before deleting anything to avoid disaster.

How to Delete 'Other' Storage on Mac

As you can see, the Other storage is not accessible. We don’t know exactly what it contains, which means we can’t get rid of it completely. Nevertheless, we can do something to reduce it to some extent, such as clearing cache junks, deleting useless documents, getting rid of unneeded downloads, and removing useless application logs and support files. Let's take a look.

Delete Cache Files

Cached files are temporary files that Mac downloads and stores after you open an app or visit a page for the first time. They are there to speed up the loading of an app or a page. If you are running low on storage space, clearing them will help you free up some space.

There are two ways to delete cached files on Mac. One is to use BuhoCleaner, the best Mac cleaner for macOS Monterey and M1 Macs, and the other is to use Finder.
