I'm going to look at a rMBP, 13", 128gb SSD, 4gb ram, with a production month of December, so it's only like 2 months old if that, and I talked him all the way down to $550 for it from $750, but what makes me wonder is that he doesn't have a box or power cord and it's pretty cheap, he says his dog ate the power cord so the dog had to get a very expensive vet surgery to get it removed and he needs the money for the vet bills. He said it still has a little charge in it @ 20%, and he is going to restore it to factory settings for me, but I'm curious as to how I can tell if it is stolen, is there any way?
