I got a MBP 13 inch Retina in July of last year, and I've loved it so far. When I went to check the storage space, it said there were 9.9GB free. Seems accurate. But, without downloading anything, I got the warning that my startup disk was almost full within minutes. I checked, and it was at about 700MB. WHAT?! I got the warning again, and it was at 100MB. Then I got the bad one, that it was full. ZERO free space. I restarted my computer, and it went back to 9.9GB only to fall AGAIN within minutes. Has anyone experienced this? What in the world is going on? Thanks.
