I know it's not officially supported, but I have the ControllerMate driver so I expect that will do fine. But I have a few questions: 1. Can you make the wheel click ("normal" feel) instead of spinning free? (That switch on the bottom--does it work on Mac?) 2. Does your Mac know when you click the wheel button? (Some other Logitech mice use wheel-click to toggle free spinning, so the Mac never receives middle clicks.) 3. Can you change the DPI? (Not in software, I'm sure, but do the +/- buttons work?) 4. Is your DPI choice stored and remembered? 5. Does the Profile button on the bottom do anything? (I don't need that--just curious.) TIA!
