CM Devastator II mouse doesn't work with my iMac late 2015 (macOS Sierra ver 10.12.5). Recently I bought a keyboard + mouse set: Cooler Master Devastator II and keyboard works fine, but mouse not. When I put mouse into usb socket mouse lights are on but nothing more happens. Is there any way to use this mouse on iMac, any drivers, or tool which can make this mouse available on iMac. Thanks up front.
