Admin account changed to standard, lost admin access!
I was trying to change Admin name and it changed it to standard account, when I try to single boot, it asks me to login w/password to continue, so I don't get to re-setup!
I DO have filevault on and I have not backed up in a long time. Yikes. What do I do.
I tried singleboot and entering
mount -uw /
rm /var/db/ .AppleSetupDone
reboot
but it keeps bringing me to login (now standard) to enter password
It also makes me login before I get the black screen to single boot
Does that make sense?
Help!
