That 'Other' space on Mac might be innocuous, but it is still annoying.

Our resident Mac Help guru, Peter Cohen, previously told us about the "Other" storage category on Mac computers and what it catalogs: In short, you're seeing space taken up by plug-ins, documents, and caches stored by OS X.

It's worth noting that these files aren't normally harmful or wasteful to your computer's system; most are intended to help your Mac run efficiently, and ideally, you shouldn't ever have to clear out your Other files. Unfortunately, they can quickly clog up a computer low on storage — especially if you're storing a large number of iPhone or iPad backups.

Whether you're looking to free up space on your hard drive or just want to do some spring cleaning, here are some simple steps to get your Mac free and clear.

How to check your storage space on your Mac

If you are concerned with how much storage space you have remaining on your Mac computer, you can check its usage folder to see how much space each category is taking up, including Other.

  1. Click on your desktop, or the Finder icon from the Dock.
  2. Select the Apple Menu icon in the upper left corner of the screen.
  3. Click on About This Mac.

Your Mac breaks down its storage categories as follows: Apps, Movies, Photos, Audio, Backups, and — that annoying, undescriptive category — Other.

How to remove cached files

Now that you know how much space your Other files are taking up, it's time to reduce their footprint on your Mac. You can start by removing items you don't need, including caches for your web browser, saved Apple Music streams, and photo previews.

A note on deleting cache folders: You only want to delete old and unncessary files, as current cache files store your preferences. We strongly recommend only deleting cache files from old apps.

  1. Click on your desktop or select the Finder icon from the Dock.
  2. Select the Go menu in the upper left corner of the screen.
  3. Click on Go to Folder.

  7. Select Move to Trash.

How to remove downloaded files

Chances are, your Downloads folder is stuffed with Other-type files, including installer packages, documents, and folders you have already made copies of somewhere else. If you want to make some room on your Mac, it may be time to clean out your Downloads folder.

  1. Click on your desktop or select the Finder icon from the Dock.
  2. Select the Go menu in the upper left corner of the screen.
  3. Click on Downloads.

  4. Select the file you wish to remove.
  5. Right-click (or control-click) on the file.
  6. Select Move to Trash.

    Deleting downloads on OS X

If you want to save a file from the Downloads folder but don't want it clogging your drive, consider moving it to an external hard drive or flash drive, or uploading it to an online storage option like Dropbox.

How to delete old device backups in iTunes

If you tend to get new iOS devices fairly regularly, you may have unnecessary device backups stored on your computer via iTunes. Backups take up 4-5GB each, on average; there's no need to hold on to older device backups if you no longer have the device or have it stored in iCloud.

  1. Open iTunes.
  2. Click on Preferences under the iTunes menu in the upper left corner of the screen.

  3. Select Devices.

  4. Select the backup you wish to delete. Do not delete the most recent backup of any device you are currently using, unless you also have it available as an iCloud backup.
  5. Select Delete Backup.

Third-party software that can help

While you don't need any third-party app to "clean" your Mac, there are very handy system access tools that make it easier to regularly remove unwanted files.

DaisyDisk

DaisyDisk scans your Mac and gives you a pie chart that makes it easy to see what files are using up the most space. You can identify files that are in the Other storage category and drag them to the delete box. - DaisyDisk - $9.99 {.cta .shop}

Onyx

Onyx is a robust Mac system access tool that, in-part, can delete caches, logs, temporary items, and other files that find their way into the Other storage category.

Cocktail

Cocktail is another useful system access tool that you can use to clear caches, purge memory, and manage hidden Apple app settings, which might be automatically sending files into the Other category abyss.
