Hi guys, I bought a second-hand mbp last year, and the warranty is about to finish next month, so I'm planning to add an applecare for it. I've been lurking around this forum for quite some time, and I knew that some legitimate Ebay seller has a pretty good bargain on Applecare. The thing is, my mbp still has factory warranty, registered under the previous owner. He said that the warranty is attached to the machine so it is automatically transferred when I bought it, and I believed him. Now, would there be any problem if I register the applecare with a different apple ID? I tried to contact the seller last month to see if he can help me registering the applecare with his apple ID, but his phone number seemed to change. Just wanted to be sure here,I would be pissed off if I couldn't use the hundred applecare that I just bought. thanks!
