I posted this in the MBP section, but realized that this is probably more of a general/help type of question. Maybe a mod could delete the other one? I am selling my 2009 MBP to my brother and I had some questions about getting it ready to give to him. I'm planning on leaving my music library on it for him. I don't want to set it back to like-new condition because it came with Snow Leopard on it, and I don't want to have to update a bunch of stuff, reinstall, etc. I basically was just wondering the best way to remove all of my old stuff from the computer (except the music library) and disassociate everything from my Apple ID and to set the user account to his name and stuff. I'm not concerned about the security of anything on the laptop since I trust my brother, and there's nothing particularly important on it. Basically I want to just clear it of all traces of me, and just leave the music on it.
