Hi all, It appears as though I have gained about 30-40+GB of space over the course of a couple of hours. I actually downloaded a 14GB video game, and gained the space when that download happened. This calculation is coming from Finder. Although the extra space is a welcome sight, I fear it may indicate a problem with my SSD. Is this just an error in Finders calculation, or could my SSD be going? It's a rMBP 15" 2012 model. I did repair the disk in Disk Utility, and everything was okay. It seems like About This Mac and Disk Utility provides a different amount of free space. Cheers! Update: After the last bootup, I lost almost 10GB.
