Hey, Upgraded to a rMBP a year and a half ago, so gave my White Macbook to my parents. It is still on Mavericks 10.9.1. My dad recently tried to install something and it promoted for the password, but I don't remember what I set it too! What are my options? I don't want to have to reinstall everything . EDIT: Argh, just realized it is in the wrong forums. Is it possible to move it to the Mavericks forums? Or should I delete?
