Hello, I just got my first new BTO MacBook Air. I want to take advantage of the 256GB. I've managed to get some GB's back by running Monolingual. In the "storage" info. it says I have 1.23GB of audio. I have not uploaded any audio content to iTunes. I think it may be all those jingles in iLife. I do not use Garageband or will be using my MBA to make any type of audio content. Did you delete all the .caf files (audio)? Any issues? Thanks.
