I just took delivery on my new G5 today. Before I try connecting my MS Natural Pro keyboard and wireless Optical Intellimouse Pro version 1 (not Bluetooth), can anyone tell me if these are supported out of the box or do I need to download MS drivers first? Lastly, I have found an MS driver for OS X and the wireless Intellimouse Pro version 2, but not 1. Can anyone enlighten me on how to get the mouse to work? Cheers, Brian
