Apple wireless keyboard
I purchased one from an eBay seller and to make a long story short it does not work. I wasted several hours trying to figure it out, between looking at the Apple support discussions, zapping my PRAM, running to the store to get new batteries, turning Bluetooth on and off, changing the passphrase options, experimenting on both the MacBook Pro and the Mac Mini... I've come to the conclusion that if it is not a hardware issue, the Bluetooth drivers in recent builds of MacOS X Leopard are flawed. It also does not make any sense to me how the OS recognizes the keyboard yet won't recognize the passphrase being inputted. Very frustrating indeed, I'm stopping by the post office tomorrow to mail it back to the seller.
