- Select the internal disk icon or your external storage devices on the desktop (If you want to check the storage space of an external disk, make sure it is connected to your Mac properly first).
- Then, press the spacebar on your keyboard, and you'll see a window open that shows the available space of your storage device. Now, check Mac disk space usage.
Also, you can see how much free space is left on your storage device in the Finder window. To do this, go to Finder, select the disk in the left column under "Locations", then press the spacebar. It works the same as the method provided above.
