If you want to know what key was pressed in a physical (or pseudo-physical) sense, you should pay attention to the keyCode of the NSEvent. If you want to know what a given key code maps to with the user's current keyboard layout, you would use UCKeyTranslate() to translate from key code to character. You specify the modifier keys which should affect translation, and for your purposes you'd specify none. To get the 'uchr' data needed as input to UCKeyTranslate(), you can query TISCopyCurrentKeyboardLayoutInputSource() to get the keyboard layout input source, then TISGetInputSourceProperty() with key kTISPropertyUnicodeKeyLayoutData. To get the keyboard type needed as input to UCKeyTranslate(), you can call the ancient (but still legal, as far as I know) LMGetKbdType() function. If you prefer, you can get a CGEvent from the NSEvent, then CGEventCreateSourceFromEvent(), then CGEventSourceGetKeyboardType().
