I have a Macbook Air(6,2) with 120 GB SSD. When I checked About This Mac --> Storage, I see inconsistent information.
It says 87.89 GB free but Apps take up 92.65 GB. So there should only be about 30 GB free according to the graphic. However, I believe the graphic is wrong because OmniDiskSweeper says Macintosh HD is ~30GB.
Why do the graphic and numbers disagree?
