Reinstall Mountain Lion on an older mac I bought a new mac and want to sell my old one. It came with Snow Leopard but I upgraded a few times since I bought it. I have deauthorized, reformatted and reinstalled OS X on my mac following the instructions here:

When I reinstalled, it installed Mountain Lion (not Snow Leopard) and asked me for my iTunes account to verify that I purchased Mountain Lion. I used Command-Q to quit after the install, so it is at the factory default welcome screen at the moment.

My question: if I sell it, is my iTunes account tied to the computer now since it asked for that during installation? And if so, is it possible to return it to an identity-free state to sell?
