I have a used iMac 3.06Ghz Core2Duo, 4GB RAM, 500GB HDD. Upon checking the serial it's a late 2009 model. When checking the hardware support coverage on the Apple website, AppleCare expires n Feb 2015! How can this be? I thought AppleCare extended from one year to 3 years, so even if the system was originally purchased in 2010, AppleCare should expire in 2013?? Are 5 year plans available?? Also, I understand AppleCare is tied to the machine rather then the user. Do I need to do anything to transfer this to myself, or can I leave it as it is and expect full warranty coverage until the end date?
