My friend has just bought an iMac off eBay, but the hard drive wasn't fully wiped - it came with the guy's user account and was obviously registered with his Apple ID still.
What we want to do is install OSX again, but first, format the drive. This is simple and I've done it before but the question is will the installer let me do this? My friend hasn't owned a machine with Lion before and I've read in several places that the Apple ID has to have a copy of Lion registered to it for the transaction to work.
Is this possible? We'd be doing it using the recovery partition.
