All RollerMouse products are pre-programmed with smart button functions. This built-in software gives users the most ergonomically beneficial set of button functions so you can just plug-and-play.
However, you may wish to use the driver to manually change button functions for even greater functionality and variation.
Mac users will need to use a driver to assign the preferred button functions to RollerMouse. Due to the difference in copy and paste commands on a Mac, the corresponding buttons on Pro2 and Free2 won’t work without the driver.
