I have a Kinesis keyboard with my Mac. I wanted to use this because it had a num lock key; and after reading the reviews I got the impression it might work. You must more clearly state "not compatible with Mac keyboard or Kinesis Advantage 2" in the product description. The problem is that Mac OS asks the user to define buttons to the left/right of the Shift keys when connected. ; what he doesn't have. So it's impossible to set up.
