How to Check Available Space on a Mac

Ever wonder how much free space is available on your Mac’s hard disk or partitions? It’s easy to check in OS X. Plus, if your Mac is running Mac OS 10.7 or later, the interface shows which types of files are taking up the most space, a feature that could help you track down space-hogging files and applications.

Checking Available Hard Drive Space on Mac OS 10.7 or Later

If your Mac is running OS 10.7 or later, here’s how to check to the available hard drive space on your Mac:

1. From the Apple menu, select About This Mac.

2. Click More Info. The About This Mac window appears.

3. Click Storage.

Note: Your startup disk should have some free space available – ideally 10% of the disk should be free. Mac OS X needs this space to operate. If you are running out of available space, it’s time to delete some files or install a new hard drive.
