If it is yours to keep, re-install MacOS?

Otherwise, have somebody hack it. Given how easy one of those was hacked at a hacking convention many years ago (5 minutes for the macboook air vs 15 hours for windows vista vs never for linux), I'd think it could be cracked.

Contact the person who sold it to you.

c/p

1. Reboot
2. Hold apple key + s key down after you hear the chime.
(command + s keys on newer Macs)
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):

mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now
