Macbook keys aren't working
Certain keys on my Macbook are not working, but I need those certain keys to enter my password. What do I do?
MacBook, macOS 10.12
I'm assuming that you have both: restarted your MacBook and tried booting up in Safe Mode, and the issue remains ... correct?
If so, I suggest that you temporarily use a wired keyboard with your notebook to see if you can enter your password.
