Mac OS X 10.6.7 has 0 room left on disk. I have tried deleting hundreds of photos, programs I don't need anymore, and files and nothing has worked. The available cap went to 3.? Gb after deleting said files. But now its back to 0 and I haven't downloaded anything. Is this a sign of a virus...? Please help. I can't even do simple things like school work bc there isn't enough room to save a one page report. EPIC FAIL.
