So I'm trying to register my recently purchased Applecare with my new iMac, During the registration process after I have entered the Applecare number and my serial number and purchase date, I get this... We're sorry, but this product does not appear to be eligible for coverage. If you believe that your product should be covered, you can submit your Proof of Purchase. If your product is eligible, it will be added to your agreement later. What's the problem here. It seems very inconvenient to have to send in proof of purchase to register my product. Is this normal and is there an easier way to register my Applecare?
