I'm trying to pair my wireless keyboard that came with my iMac 21.5" with my MBP 17". But for some reason its not even coming up in the bluetooth browse. I have turned the on button on & off several times. Its not even blinking indicating it can't pair. I have taken the batteries out and reloaded to reset, still no luck. Seems that the wireless keyboards that are bundled with the new iMacs are specifically paired. Is there a way to "un-pair" them? The wireless mouse that came with my iMac is paired fine with no problems to my MBP. Just can't get the wireless keyboard to work. Any ideas/suggestions?
