Thought i would share this with all of you running Power Macs with no bluetooth. I was just working on my Digital Audio running 9.2.2 and had connected it to my cinema display with a Logitech K750 wireless dongle connected to it. I thought I'd see if anything would happen when I used the keyboard and lo and behold it is recognized. This is my main keyboard and I couldn't be happier that support goes this far back.
