Hi, I booted up my MacBook this morning and a grey progress bar appeared at the bottom along with the normal spinner. Well after this update installed (thats what Im thinking it was) it warned me I had no disk space left. A had 57% last night! What ever that progress bar did ate up 38.7GBs of space! If anyone has help to get back my disk space it would be nice. I only have 500MBs left.
