My keyboard is currently not working (literally nothing appears on a password screen when I start typing, both in safe mode and in normal mode). I am currently typing this on an external keyboard. I have tried:

  • NVRAM reset
  • SMC reset
  • Removing the password from the password screen
  • Trying another user account, no go.
  • I would really prefer not to wipe the system.

I just want to know if this is a hardware thing or just a software one. I would like to believe that it's just software because I can get to safe mode (pressing Shift), do NVRAM reset (ShiftOptionPR), and get to the recovery partitions all on the internal keyboard.

How can I fix this?

Update: Hardware diagnostics (pressing D on the internal keyboard whens starting the machine) did not find something wrong with they keyboard

Update: I don't think this is a duplicate of Keyboard key stuck or not being recognized; how to fix as I am able to boot to recovery/safe mode.

  • Since you can boot to other modes that require keyboard commands, there's a good change it's software based. But to help confirm, if you boot to recovery mode (hold Command-R while booting) you should be able to open a terminal application from the menu. Do all of your letters and numbers output? – moneyt Oct 27 '17 at 20:36
  • @moneyt no keys work in recovery mode. :( – Daryll Santos Oct 29 '17 at 8:47

Since the hardware diagnostics test did not find anything wrong with the keyboard, this is more than likely a software glitch.

Take your laptop into an Apple Store, they always help out with things like this.
