Hello I purchased my macbook secondhand a very long time ago, not knowing it still had AppleCare. Now my laptop won't turn on and by chance I entered the serial number into the Apple website and found out that it is still entirely covered. Thing is, I don't have any information of the guy I bought it from, I don't even remember his name. So now I'm sure the AppleCare is under his name, but I wasn't able to even find that information to try to contact him to change the ownership to me. I have to take in the laptop for repair but they will for sure ask me some information about him and since I don't anything, it completley looks like I stole the computer. Any ideas of what to do? I read that the warranty is actually attatched to the laptop and not the owner, but then why would they request to switch ownership? Any help would be greatly appreciated.
