As you can see with the attached screenshot, I have a 500 GB SSD on my MBP with Retina display. But Finder says that there is 587.51 GB free. This is obviously wrong. I've read on various other forums that it has something to do with local "snapshot" backups that were introduced in Lion. I don't want to disable this (there's some terminal command that can disable that), but I want Finder to display the right amount of space. I also only have 258.13 GB used (Finder should ignore the local backups, they are not counted in this total), so you can tell that System Profiler isn't correctly adding up files itself either. I just don't know what to do. I tried reindexing on Lion, but that didn't help. At this point I just want to go to the Genius bar and see what they can do about it. Thanks for any and all help or comments!
