I recently purchases a used mac. It has the old user name all over it and I can't figure out how to change it. I changed the admin to myself but the users didn't change, nor did the settings such as the name when the password box pops up. I can see a different name as a folder name (not person's full name as I keep seeing) under user and I tried to change that but it's locked.
Thank you in advance.
