So incredibly frustrating. BTO 27" finally arrives today and the keyboard won't pair. Tried my old wireless keyboard from my 2009 24" and it will "pair" but won't recognize the 8 digit key when I try to type it in (it basically doesn't regster the keystrokes). Called Apple Care and they basically said bring it in to a store. Anyone have any recommendations on alternatives that would save me from going to the store which is an hour away?
