I am writing especially for Mac users. To know that it works very well. Then all of the elements making more of this mouse disappear without Windows drivers. Customizing LED, IPR, etc ... nothing works. Only the additional buttons on the sound control mice are functional You need to install additional software on mac to customize a little more this mouse including the movement speed is extremely slow even with the default settings to 100%. Otherwise the ergonomics are excellent for righties, the grip is nice for gaming, the scroll is very accurate.
