How can I retrieve an admin user name?
My mac pro (mid 2012) recently froze up. I did a hard reboot, and the system will only come up as a guest user. I thought I knew my admin name, full first & last name. I do know the password. But, it will not accept the name. Is there a way to find the admin name?
MacBook Pro, OS X El Capitan (10.11.6)
