My hard drive on my Mid 2009 model MacBook Pro seems to fill up with what appears to be nothing. I moved all of my movies and videos to an external hard drive and deleted them from iTunes. Next I deleted all major applications that took enormous amounts of space. (Call of Duty: Modern Warfare, The Sims 3 etc.) Then I cleared my caches from my computer and restarted the MacBook and emptied the trash. I also ran the program "OnyX" to ensure that I had touched all of the important things. Now the only thing on my hard drive is about 5 GB of Music and several Apps from the App Store that are minimal on storage. I have a 160 GB (159.7 GB) Hard Drive and I've used 96.94 GB and have 62.76 GB Left. I just don't see how I seemed to occupy 62.76 GB worth of stuff on my Mac. The applications on the machine are FaceTop, Angry Birds, Flight Control HD, Pinball HD, Pangea Arcade, Pac Man, FaceTime, Skype, and Microsoft Office 2008. Other than Microsoft Office I don't see how any of these other applications are going to add up to this amount of space on the hard drive. Any ideas?
