What is "Other" in Mac Storage?

According to Apple, system files and files not recognized by the system will be marked as "Other". Here's what it might contain.

  • 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 Other Storage on Mac

Apple has made some changes to the storage category in a recent update to macOS Monterey. In the latest macOS, there is no Other storage and it is replaced by System Data storage. However, if you're using macOS Big Sur or an earlier version, the Other storage is still available. You can check it by following these steps.

  1. Click the Apple Menu > About This Mac > Storage.
  2. After the storage analysis is complete, you will see your storage space divided into several different colored sections, including Apps, Documents, Movies, Photos, System, Other, and more.
  3. Click the Manage button above the storage bar to open the storage management window. In the lower-left corner of the window, you will see a category named Other and the size of the space it occupies.

If you don't see the Manage button above the storage bar, open Terminal and run the command: open -a "Storage Management.app" to open the storage management window.

Can I Delete Other Storage on Mac?

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 it will have on your macOS 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 alone. In addition, it is strongly recommended that you make a full backup of your system before deleting anything so as to avoid a potential disaster.

How to Delete 'Other' Storage on Mac

As you can see, the contents of Other storage are not easily accessible. We don’t know exactly what it contains, which means we can’t safely 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 on Mac

Cached files are temporary files that your 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 your Mac is running low on storage space, clearing them will free up some space.
