I recently sold my old MBP on eBay and now the buyer is flipping out on me telling me he can't do anything on it because when I erased the hard drive and reinstalled osx it linked to my apple ID and I'm the administrator on the laptop, meaning it won't let him do anything. I linked him to the erase and reinstall instructions on apple's website for OSX but he claims he can't do anything because I'm an administrator on it? Can he seriously not wipe the hard drive and reinstall os x using his own apple ID because it's linked to mine? Any ideas? I'm certainly not giving this guy my password and I don't know what else to do or tell him. I have a feeling he's about to dispute the money with PayPal and I'll be screwed. Edit: He just opened a dispute on eBay and is demanding I refund his his money as I was typing this.
