So I plan on buying a Macbook Pro once they get updated and plan on adding 4GB of RAM from OWC, and was wondering if this will void the Applecare warrenty? I asked a guy at the Apple store and he said it would but I didn't see why. I know it would void the warrenty if I broke something while I was installng the RAM. If something were to go wrong with the computer, couldn't I just put the original 2GB that will come with the computer back into the machine and send it in like that or is there a way they can tell that I have changed the RAM in the computer? Thanks for the replys.
