soooo I used to have over 55 GB free on my rMBP with barely anything installed but now my mac says 67 GB of "Apps" which doesnt make any sense at all as shown in those screenshots below:
Application Folder:
Mobile Applications (iTunes):
It shouldnt be more than 20 GB of "Apps" ...
any ideas? is there a program of some sort that tells me exactly how much is taken up by which files?
