What Is “System” In Mac Storage? Here’s The Truth & How To Remove It!

You’re running out of storage space and you don’t know what to do. You noticed that System is taking up a lot of storage space and you’re not sure why. In this article, I’ll explain what “System” in Mac storage is and show you how to remove it!

System in Mac Storage: Explained

The “System” in Mac storage consists of mainly backups and cached files. It’s designed to store your Mac’s temporary files. Your Mac’s storage space starts to fill up quickly when it saves a bunch of temporary files.

Macs automatically delete some temporary files. However, other useless files aren’t always deleted, leading to a large chunk of System in Mac storage.

How to Remove System From Mac Storage

First, click on the Apple icon in the upper left-hand corner of the screen. Then, click About This Mac -> Storage. Here you’ll find exactly what’s taking up space on your Mac. As you can see, System currently takes up 10.84 GB of storage.

Another way to clear out System in Mac storage is to rebuild the Spotlight index on your Mac. If you’re having some issues with Spotlight search, this will help you fix the problem.

Click on the Apple icon in the upper left-hand corner of the screen. Then, click System Preferences -> Spotlight. Finally, click the Privacy tab.

Tap the plus button (+) in the lower left-hand corner of the window to add the types of files you’d like to reindex. I recommend choosing every file type if this is your first time reindexing Spotlight. Click Choose in the lower right-hand corner of the window once you’ve selected the files you want to reindex.
