I have an early 2011 macbook pro. It went from having 150 gb of free space to being almost out of space in a matter of 4-5 months. I checked under 'about this mac' to see what could be taking up all of this space. My audio, movies, photos, and apps take up only about 100 gb of my 300 gb hard drive. Over 150 gb is taken by what it labels as 'other'. What in 'other' could be taking up this kind of space? Any help is great!
I have already used ccleaner, tidy up, app cleaner, and other basic things i found of the internet.
