Hi guys, I've found a 27" iMac for a good price and I'm taking a look at it tonight. The iMac comes with the original box and receipt from date of purchase. The receipt contains the sellers name and personal info, as well as shipping adress of his residence. Should be OK right? It was purchased privately so it's not company issued or something along those lines. I have the serial number of the computer, in case anyone know of a place where I could run it? I entered it on the Apple Serial No. website and it clearly states that it is a 27" Late 2013 iMac. Nothing else however. Anything else to look out for? It's a lot of money for a used device, which is out of warranty (purchased in feb 2014). Just want to make sure it's OK before taking the plunge. Thanks in advance!
