I have a 120GB MBP, the total capacity is 111.47GB (after the OS X), apparently I have only 67.64GB of space available. I have used up 43.83GB of space and I don't know how. I have 8.54GB of music, 14.37GB of applications and 5.11GB of movies, documents, pictures and other miscellaneous items doesn't even add up to 1GB, the total space used should be roughly 30GB. How did I end up using 44GB? I don't understand :/ Can someone please tell me whats going on?
