I have the option of buying a new MBP from someone I know on my design course. He brought 2 back from Hong Kong. Still sealed. The thing is do I need a receipt for it for my warranty to be valid? Or do I have to register the MBP once opened? I found this from the apples website but didnt really help me: All new Hardware carries a one-year limited warranty against defects in materials and workmanship.
