Hello all:
I have last model MacBook air with external keyboard.
I have been changing keyboard layouts and accidentally deleted apple keyboard file.
Now when turning MacBook air on, keyboard doesn't work, I can't type the password and so can't log in.
Please help.!
MacBook Air (11-inch, Mid 2012), OS X Mountain Lion (10.8.1)
Welcome to Apple Support Communities
Press Command and R keys on boot and reinstall Mountain Lion
I was able to log in with guest account and activate the keyboard.
Than, I got the file "AppleKeyboardLayouts.bundle" from a friend Macbook.
Copied the file to "/System/Library/Keyboard Layouts"
(macbook asked for user and password).
Turned off, turned on again and keyboard is now working fine.
Thank you.
Keyboard not working. Can't log in
