As you see from the title, I am getting ready to sell my MBP. It came originally with Leopard installed - I then upgraded to SL from a purchased Disk, and then to Lion from the App Store

My thought is return it to SL and sell it with the Disk, but how do I "unregister" the Lion instillation?


Thanks for any pointers!
