Hey guys, So I am interested in buying a MCP retina off a person who bought it in September of this year. 15' 16 gig ram 256 SSD for about $1300. The person has the receipt for the original purchase and is willing to meet me at the Apple Store as well. My question is aside from doing a diagnostic test on the computer, what else should I look for? How would I check for any dead pixels it might have? And as far as the purchase goes, is there anything I should/could do to transfer the laptop under my name if it's possible? Regarding AppleCare the laptop doesn't have it but I'm told that you can purchase it a year after you buy the laptop so that gives me until September next year to do it. Any advice would be helpful. Thank you!
