I'm not asking about pricing stuff because i'm now aware that it is against the rules. I am curious about how to prepare a macbook for sale so that privacy is not an issue. Obviously you can delete your itunes library and your photos and contacts and all of that stuff, and clear your browsing history, internet cache, etc... Is there anything else that needs to be done? Is it worth while to do a fresh install of OSX using the disc that comes with your macbook? Any tips?
