This question already has an answer here:

I usually check the Hard Drive capacity in the Activity Monitor. But when I checked it, it literally looked different. I selected each tabs, trying to find the information about my disk but to no avail. How can I find the disk occupied in my hard drive?

You can check it via Finder. Just select the Hard Drive and press CMD + I.


  1. Click on the Apple icon on the menu bar
  2. Select About This Mac, then click on More Info.
  3. Select Storage
