So this is bizarre... I have a 256GB SSD in my Macbook Pro. Yesterday, I had about 120GB's of free space. Today, my wife is working on some photo editing and the computer goes bonkers and I take over and it says there is no disk space left. WTF? So I look and sure enough, it's at 1.3MB. I delete a few things and get it up to about 15GB's and I can't for the life of me figure out what is going on. I downloaded THREE hard drive programs to get a picture of what's going on... For starters: So you can see I've gotten it up to 26GB now, and the drive is in fact 256GB. But when I loaded up these programs... It shows that only about 100GB's of space are actually taken up...there is nothing saying I have more than 100GB-ish used up. What is going on!?!? I found this thread here on MacRumors... http://forums.macrumors.com/showthread.php?t=1329717 Seems like the guy is having the same problem, he runs verify disk in Disk Utility and it tells him to reboot in repair mode and it fixes it...I tried verifying and it worked fine... So it's not the exact same issue. I tried rebooting into repair mode, and it didn't do anything. Well this is infuriating.
