The mouse requires at least Mac OS X 10.5.8. It can be configured as a two-buttoned left-handed or right-handed mouse, but the default is a single button. It uses laser tracking for increased pointer accuracy over previous generation Apple mice. Since its release, it has been included along with a wireless keyboard with the 2009 generation of iMacs, and with a wired keyboard with the 2010 Mac Pro workstations. It can also be purchased separately.
