Hi, I just have one question: What if someone gets a Macbook Pro as a gift (obviously no receipt) and there are some problems with it and the person goes to the support and they ask him for the proof of purchase? I checked the apple's site (http://www.apple.com/support/macbookpro/service/) and they say: How can I tell if my MacBook Pro is in warranty? Visit the MacBook Pro Support page and enter your serial number in the About Your Support Coverage box to find out how many days remain on your warranty or AppleCare Protection Plan. Apple may need to examine your proof-of-purchase document to verify your MacBook Pro warranty status. How will the warranty apply if the person does not have the proof of purchase (but the person may have registered the macbook pro under his name)?
