I just sold my MacBook Pro. It originally came with OS X 10.6.6 (snow leopard). I since upgraded it, through the App Store, to OS X 10.7.5 (lion).
I want to wipe everything clean on the hard drive so the new owner starts fresh. I have the original Install DVD. Should I just insert that and format the drive? Is there an easier way, like with iPhones, that I can click on something?
After resetting everything, do I then need to go to the App Store with my Apple ID, install Lion, and then erase my Apple ID?
