Unable to boot Mac. Single user mode not working I lost admin access when I tried to change user name on my Mac. I have entered into single user mode, entered all the commands suggested (including the spaces) and it isn't working. It continues to reboot with zero change. What can I do? I'm open to all suggestions.
did you do the single person commands?
did you type them correctly?

/sbin/mount -uw /
rm /var/db/.applesetupdone
