I just bought Logitech's MX5000 bluetooth mouse/keyboard set. The mouse works well, but the keyboard doesn't work at all. The volume & mute buttons work on the keyboard, but none of the rest of the keys do. I haven't installed Logitech Control Center yet, because I've heard horror stories about kernal panics and secret software installs about it, and would prefer to run the keyboard without it. Has anyone got one working on their Mac? Any advice?
