I really messed up! Since I ran my Mac with the command below
chsh -s /usr/local/bin/false
Several minutes later, I noticed my Mac logged out by itself. So, I tried to log back in by clicking 'change user' But I can't see my administer account there.
I guess 'false' is not a loggin-able shell, that's why my account is hidden.
I'm trying to change my shell with Terminal.app on recovery mode or single-user-mode (but both are read-only).
So right now, I want to know if there's any solutions that might be able to fix this problem.
