I decide to take the plung and I bought the Logitech MX900 and the kyboard in the set, since i want and external keyobard. I figured it would work because its bluetooth, a stanard platform. It says it won't work with a mac, but it works the only thing that doesn't work are the hot keys like the email, messenger, etc. The only buttons that work are the volume and expose buttons. Any idea on how to program the hot buttons. I have the same issue on the mouse. I would like to program the back/foward button on the mouse for safari use. Thanks for your help!
