My Dad recently gave me his MacBook Pro. I formatted the hard drive and popped in the disc for a clean installation of Lion and it prompted me to input an Apple ID and password. After inputting my old user name and password, it said that my user ID did not purchase a copy of Lion and therefore cannot continue with the installation. Only my Dad's Apple ID will work. Is there some way around this or can my Dad log in to his account and transfer his copy of Lion to my account? I want his computer and his copy of Lion OS that came with it registered under my account.
