I have a 250GB SDD, and AboutThisMAC is showing 191GB available, but ALSO showing the SYSTEM taking up 159GB. I've scoured the forums and cannot find an answer to this strange occurrence.
I already rebuilt the Spotlight cache (add HDD to privacy, reboot, remove HDD from privacy, reboot)
I also check the TimeMachine, but since I haven't used it, it had no backups
Help?! (and thank you)
