The built in keyboard and trackpad on my 2017 Macbook Air were damaged by liquid and do not work. Luckily I can boot the machine to the login screen where I can plug in an external keyboard and mouse (USB-C), both of which work. The problem is I cannot remember my password, so I have to boot to recovery mode to reset it. When I get to the recovery screen my external mouse and keyboard no longer work. Any thoughts on why this would be the case or any alternative solutions would be greatly appreciated.
