Disk utility & System Information shows me that on my internal SSD I have 72.1 GB of free space. But under "Get Info" on the "Macintosh HD", and the icon on my desktop, shows me that I have 101.87 GB of free space. I know I dont have that much stuff on my internal. NO music, 2.5GB of photos and videos, a couple apps (the biggest one is VLC!), 4.55GB Total. I have my time machine backups going to an external when I want them to, and thats on a 1.5TB FW800 External with a partitioned 100GB specifically for backups. So why is disk utility saying I have used 48.37GB!?!?! Theres no way. I'm trying to figure this out before I install my 2nd SSD into the optical bay slot, which I will use it for music (60GB) and everything else I stated above. That way pretty much the only thing on the boot drive, is the OS. But somethings not right here... what can I do to get the correct amount of disk space and free up the extra unused GB's?
