If you need to look up how much of your Mac’s disk space is being used, you can simply choose About This Mac from the Apple menu, and then click the More Info button to bring up the system information summary. In here, you can click the Storage section, to see all attached hard drives and a colorized breakdown of the file types and sizes stored on each. While this feature is convenient, sometimes it may not show an accurate breakdown of the space used.
In some instances, you may see the calculated amount of free disk space differ from that when you select your hard drive in the Finder and press Command-i to get information on it, and at other times while the total disk space calculation might be correct, the breakdown does not seem correct. For instance, you may see the “Other” file type category taking up a large portion (if not all) of the calculated space used.
- Open the Spotlight system preferences.
- Go to the Privacy tab.
- Drag your hard drive to the list to add it.
- Select your drive, and then click the minus button to remove it.
Perform these steps for any hard drive that shows an improper storage calculation in the About This Mac window.
When you complete these steps, if you check the storage calculations before indexing is complete, then you will see the About This Mac window progressively update and change as more files are added to Spotlight’s index. Therefore, wait for the Spotlight index to fully rebuild (the progress of which can be seen by opening the Spotlight menu) before you check the storage use in the About This Mac window again.
Thank you so much!
Saved me from a huge confusion where the About this Mac said i had 933 GB available out of 999… but with 400 GB of apps taking up most of my bar (which i dont have… i have almost none)
Still having trouble, pls reply
It didn’t work for me. I’m running OS 10.10.3. It says I have over 141 TB free on a 1 TB drive.
try disabling the local time machine… worked for me
Yes, the local time machine did it, toggle it off and the 141 TBs go away
How do you do it with the built in hard drive?
Did not work for me even with Time Machine off.
is the problem solved yet. I have the same issue.
I have migrated all my data, apps and system from one mbp to another (exactly the same configuration). The 2 mbp seem identical now, but they show different free space in internal HD (almost 15 gigas) and they show completely different breakdowns in “about this mac” storage. Can someone explain me how is that possible. I have to return one of the mbp and I’m not sure the new one has everything.
Emptying your “Trash” will also helps
