Mac "Other" Storage Huge? Here's How to Delete It

In macOS Big Sur and earlier versions, you may notice a storage space called Other, which varies in size from tens to hundreds of gigabytes. If you are suffering from insufficient storage space, clearing the Other storage space will undoubtedly free up the most disk space. So, what exactly is the Other storage on your Mac? Can you delete it? And most importantly, how should you clear it?

Read this article and you will find all the answers.

What Is Other in Mac Storage?

"Other" in Mac storage comprises files that don't fall into specific categories like Applications, Documents, Photos, or Apps. While these files won't harm your Mac, they can occupy storage space.

Here are some examples of what it might contain:

• macOS system and temporary files.
• PDFs, .psd files, .doc files, and other file types.
• Cache files from apps, browsers, and the system.
• Installer packages.
• Browser plugins and app extensions.

How to Check Other Storage on Mac

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.

   

Why Is Other Storage on Mac So Large?

As mentioned, Other storage includes various types of files. Over time, these files can accumulate on your Mac, taking up a lot of storage space.

Can I Delete Other Storage on Mac?

Yes, but be careful. Files like .dmgs 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 Clear 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.

Clear Cache 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.
