After update only Guest user showing
Cannot log in after update. Only Guest user showing.
Previous discussions say to reset password through terminal in Recovery mode.
Impossible as when doing that it shows no accounts/users so nothing to click to reset. Did not understand about resetpassword root. Typed just that. nothing changed.
Disk utility - ran the first aid and it said done and fine but no change.
Help!
