How do I factory reset a MacBook that’s still linked to a previous user?
Long story short: Coworker left. I have their MacBook- but it wants me to log in as them. I've tried to erase the memory so I can download a new iOs and start over. Instead it keeps wanting me to log in as them just to even do that. How can I bypass this and get this thing wiped clean? Do I need to go to a Mac store?
