My macbook's (running Catalina) internal keyboard is misbehaving after a water spill. It thinks the ctrl key is pressed. With an external usb keyboard i am able to get to the recovery mode, enter passwd and mount/access the file system as root. But the external keyboard doesn't work in the login screen (behaves the same way as the internal keyboard. Makes me wonder if the keyboard driver works differently in login vs recovery). NVRAM/PRAM and SMC resets are not helping either.
From the command line is there a way to enable the on-screen accessibility keyboard ? Tried "defaults read" on a different machine and i do not see the key for "Accessibility keyboard". Or any other option to bypass the login screen from recovery mode ?
