This question already has an answer here:
The D key on my built-in keyboard (MacBook Pro) is stuck and it keeps looping into self diagnostic when I boot up. I would like to disable the keyboard during computer startup and go straight to the external keyboard but have not found a way to do this.
If I install Karabiner on my MacBook Pro and disable in Karabiner settings the built in keyboard, after I turn off the MacBook Pro and start it up again with the external keyboard plugged in, would the built in keyboard function during the start up or would it be disabled?
If not is there another way to disable the builtin keyboard during startup?
