Just the keyboard form the 7000 Wireless Entertainment Desktop set aimed to Media Center PCs, not interested on the mouse. I think it comes with a USB Bluetooth transceiver… so I guess you wouldn't need it at all -it's missed- given the Mac has built-in BT, right?.
Would be that an issue under VMware Fusion?, my Mighty Mouse wireless works well under Fusion but I guess that says nothing.
As for functionality, any idea which software you may use for it?, cause SteerMouse, USB Overdrive… are mice only drivers after all.
