Keyboard not working! Some keys to odd letters
My keyboard is not working after clean installation to OS X El Capitan (Macbook Pro late 2012), doesn't type most keys, and the very few that work don't output the correct letters (function).
Keyboard viewer shows correct keys, when typing.
Tried to install El Capitan, and same problem.
Reset SMC, same problem.
External keyboard works, but native keyboard won't.
Does anybody knows how to solve this?
