I bought a MACBOOK PRO in February. I recently bought the apple protection plan and when I tried to register it, it told me that the SERIAL # for my machine did not exist so I was unable to register it. The serial # appears in about this MAC and on the box. I've checked a million times to be correct and it is. Has anybody had this problem? Nobody that know has ever had this problem. And I can't contact the Apple website for help because they ask me for the serial as well. I bought my computer at MACMALL.com so I assume it's legit. Thanks for the help.
