NIKODEMUS I would be leery of installing this driver since OSX handles the Razer mice natively. I've tried USB Overdrive and it just doesn't have the right feel afterwards. Sadly, Razer's new Copperhead mouse doesn't even work on the Mac correctly. I own 5 Diamondbacks, best mice in the whole damn world in my opinion but Razer falls short (flat on their faces) when it comes to the Mac platform. I agree with the last poster about these drivers, I don't feel like playing the install and uninstall game. Just plug your Razer mouse in the keyboard and enjoy a great mouse without any drivers.
