I've got a 3 year old Macbook Pro and the former owner set me up as an administrator, and we deleted his old initial set-up admin. account. However now on the window log-in on start up I still she his name. How do I change that? I can still log in as me but the "computer name" I guess is still stuck on the original owner's set up name.
Found the answer. You can change your computer's name under Preferences>Sharing.
