Apologize in advance for another "preparing my Mac for sale" thread, but after searching the forum I'm still confused. I'm selling my early-2011 15" MBP on eBay. It came with the SL DVD, but I have since upgraded to Lion through the App Store. Most everything I've read is pretty clear that I can only clean install SL since the Lion upgrade was through the App store and tied to my Apple ID. Unfortunately, this is my first Mac sale and I didn't realize that. So on eBay, I've told the bidders that they will receive the machine with Lion installed. I found this: http://support.apple.com/kb/HT4718?viewlocale=en_US&locale=en_US - but I'm not sure that option works for an upgrade to Lion from SL. Is there a way to actually deliver the machine with Lion? Or perhaps I should just take $30.00 off the price once the bidding is over. I'm afraid it's going to look like an eBay bait and switch due to my ignorance. Thanks for any help, and apologize again for beating a dead horse.
