MacBook Pro A1502 firmware password
In our company we have lots of MacBooks for our staff. One of the older ones has had a firmware password applied by an employee that has since left. I understand that a Mac service centre can reset this so we can install a fresh OS?
If that's the case, what do I need to take to the Apple Store?
Can I wait whilst it's carried out?
Is there a cost - if so how much?
