How do I get OS X 10.11.6 to return my free space? I've cleared quite a bit of my user files off my Mac, and have restarted. The disk utility shows this:



but a df -h in the terminal as I clear never changes from 89 GB free, and when I try to restore some things from Time Machine, the 'not enough space' message reflects the df results, which should be wrong, instead of the disk utility display.

I only have the one volume on my hard drive.

This isn't the same question as the proposed duplicated, at all. I am not suggesting that anything is eating my disk space. I'm also not saying that restarting it changes anything. I'm stating that the disk util says I have 300 GB free, which is likely the case given what I deleted, and the OS says ~90 GB free, an amount that did not change as I was deleting things and did not change when restarting the system...so basically the freed space was not given back.
Rebuilt the spotlight, then rebooted and reran disk utility. 
It showed a problem with the free space index. 
Rebooted into recovery, ran the disk util, and it repaired the disk. Unfortunately, df -h (the lower free space amount) seems to have been correct all along, and disk utility and selecting info for the drive from finder were incorrect. 
All are in sync now.
