When you click Manage, System Information launches, and the Storage Management window appears. You can’t do much here, but the view gives you a quick overview of your usage. The hashed “Purgeable” section includes caches and trash files, anything that the computer is willing to delete should you need space for something else. The grey “System” data can be a myriad of things from settings files to application database files. The white space at the end of the bar shows space that’s still available. Hover over each colored bar to see how much space is taken up by a particular type of data. To launch Storage Management, click the Apple logo > About This Mac, click the Storage tab, and then click Manage… but wait! Before you click Manage, look at the About This Mac window’s Storage view.

SSDs are great-they’re fast, durable, and reliable-but they’re also expensive, which results in many of us not having as much storage built into our Macs as we’d like, especially if you didn’t choose to upgrade the storage when you bought your Mac, or for those who download videos in iTunes or take a lot of photos.īut Apple has a built-in tool for cleaning house: Storage Management.
