Managing the Mac storage is still a great concern for users even in 2022 because it's filled up with various files so quickly. Especially for MacBook Pro and MacBook Air that you can't upgrade the storage capacity, taking advantage of the "Other" storage on Mac becomes necessary.

The thing is, most of you don't know exactly what files are taking up the Other Mac storage. So, when confronted with the pop-up "Your disk is almost full", or stuck with a frozen or slow Mac, you are afraid to delete the Other files from Mac internal hard drive to free up space.

No more worries now! This post explains what the "Other" storage is on Mac in detail, so that you can know what large files on Mac are taking up those space, where you can find and delete those unnecessary files to speed up your Mac.

What is "Other" on Mac storage?

"Other" storage on Mac contains files that macOS can't categorize into any known forms, such as Documents, Photos, Apps, Movies, Audio, etc. The Other folder on Mac can fill up fast with cached and temporary files and other file types.

As we mentioned above, deleting the "Other" files on Mac storage helps optimize your Mac. However, not all the files stored in the Other storage category are junk files.

Removing important system files or application support files could cause serious problems with system operations or result in apps no longer working properly. Thus, it's necessary to know what kind of file types and formats will be classified into "Other" storage before you start deleting unneeded files off your Mac.

Other storage on Mac includes the following types of files:

  • Unsupported documents and file types like PDF, PSD, DOC, etc.
  • macOS system files and temporary files.
  • Cache files like user cache, browser cache, and system cache.
  • Archives and disk images like ZIP, ISO, and DMG files.
  • App plugins, extensions, accessories, fonts, and installer packages.
  • Out-of-date backups and any other files that don't fit into the main macOS storage category.

How to Check disk space on your Mac?

Now that you've known what files are taking up the Other storage on Mac, the first step to clear Other storage and free up space on Macintosh HD is to find out how much space is used on your Mac internal hard drive. Here's how to do:

Step 1: Click the Apple logo at the top left corner of your Mac computer.

Step 2: Choose About this Mac from the dropdown menu.

About This Mac

Step 3: Select Storage tab from the pop-up window.

Step 4: Wait for a second and then system will return the results of whole storage space, used space, and free space.

Now, you can find how much storage space is still available on this Mac. If you move your mouse cursor to the greyed column among the whole storage bar, you'll see how much space the Other storage category is taking up.

How to access Other storage on Mac?

To access the files in the Other storage on Mac, you should look at your Library folder. Most files in Other Storage are located in the macOS hidden Library folder. Apple hides those service files to prevent the accidental deletion of important files that could cause applications or operating system crashes.

Here's how to open your Library folder so you can find out what files are stored in "Other":

Step 1: Open Finder and select Go from the menu bar.

Step 2: Hold down the Option key on your keyboard and click Library when it appears in the dropdown menu.

Another way to go to this Library folder is to select Go to Folder from the same dropdown menu and then enter "~/Library".

Step 3: You'll now see all the system files and application support files in the Library folder. As aforementioned, system support files, caches, and other service files are included in the Other category.

Is it safe to delete "Other" Storage on Mac?

You can remove certain files from the "Other" storage on Mac to free up space. But it's not 100% safe to clear those files because not all the files under the Other label are always junk files or unnecessary files.

Most of the time, files put in the Other storage can be distinguished from their name and types, which helps decide if it's removable. For example, DMG files of software installers that are left in the Downloads folder after installation can be cleared for sure.

And website caches and cookies from Google Chrome, Safari, or Firefox sometimes could be reloaded the next time when visiting that page, which won't be a pain. However, you could lose browser history when clearing caches on Mac, and get troubles in running a certain app if deleting its extensions.

Therefore, when clearing Other storage on Mac, resist touching any files if you don't understand what they are used for, as it could be disastrous. We also recommend you back up files on Mac with Time Machine or other tools before beginning.

Tips: If important files are mistakenly cleared during this process, we recommend a deleted file recovery from the Mac using iBoysoft Data Recovery for Mac.

There will be recommendations from Storage Management to optimize the Mac storage, which should be different from Mac to Mac. Here it is advised to save files to iCloud to free up local space, remove watched movies and TVs, enable 30-day automatic Trash empty, and reduce clutter.

However, Storage Management makes a little difference when "Other" bloated the storage over 100GB. This happens frequently if you newly updated a macOS. In this case, you need to free up space by manually deleting files in "Other".

2. Clear system temporary files located in Other storage

Temporary files are created every second when your computer is running. Those files are piled up when apps are launched and performing, while they are prone to be outdated and replaced by new temporary files. As a result, they will stay on the Other storage of your hard drive, wasting space until you delete it manually like this:

Step 1: Open the Finder app and click on Go at the top left.

Step 2: Click Go to Folder ( or press Command + Shift + G ) and then type in ~/Users/User/Library/Application Support/.

7. Clear unnecessary plugins and extensions from the Other storage

You may use a lot of add-ons to make apps on your Mac better, especially for browsers like Google Chrome, Safari, and Firefox. But those web browser extensions are separate from the software itself, but categorized into the Other storage.

After confirming that you don't want those plugins or extensions anymore, go to the browser that on your Mac and delete Internet plugins manually. Here takes Google Chrome as an example:

Other ways to Optimize and Manage Mac Storage

Except for getting rid of the files saved on the Other storage, there are some other ways to free up Mac space.

When the internal hard drive is almost full, you can save files, photos, and messages to iCloud drive to relieve the local disk and will download when you open it. This will optimize storage and speed up your Mac by only keeping recent files.

Time Machine is also a way to release free space. You can back up your Mac files to an external hard drive and then clear up files on the Mac hard drive, which makes more room locally.

Also, It's better if you get a regular habit of emptying Mac Trash, deleting duplicated files with duplicate file finder for Mac, and uninstalling applications that you don't use.

Clean and Speed up Mac with Third-party Software

We have made it clear that manually clearing up space is risky. You can't decide which one should be deleted and which not. Why not let someone skilled at this task? Yes, here we mean third-party Mac cleaners though you need to pay for that.
