I am on a mid 2012 macbook pro (not retina) running 10.8.2.
I have connected my A1048 Apple Keyboard:
Most of the keys work fine, except the four keys above the numpad:
Volume Down, Volume Up, Mute and Eject.
Keyboard viewer doesn't show them either:
Keyboard setup assistant doesn't recognize the keyboard:
(the key is a "Z")
What should I do to make those keys work? I don't really need the Eject key but I use the other three quite often. Also, the keys work on my older (early 2008) macbook pro with 10.6.8.
