I had a 15" pro which I took to Apple for repairs, but the cost was so high that I decided skip the repairs and just get a new machine (refurbished 13"). My old computer was still functional when I took it to Apple (as long as the charger was connected), but when they gave it back it had stopped working completely; it won't turn on at all. The problem is that I never made a backup of the old computer (I know, I know), but there's a lot of information, particularly the iTunes stuff, that I'd really like to get back if possible. Is there anything I can do at this point to get my files? Is cloning the hard drive something a person with very little experience can do, or would it be better to take it back to Apple/somewhere else and see if they can do it?
