MouseWorks has never worked satisfactorily under Leopard. Here we are in 2009, three years after the release of this version of MouseWorks. Apple has come out with a whole new operating system, Snow Leopard, yet Kensington is still stuck back in the days of Tiger.

Clearly, Kensington has no interest in the Mac market. Their hardware will work, but only after you spend ANOTHER twenty bucks on third party drivers.

If other developers can create software that will handle Kensington input devices, one would thing that Kensington could do the same, yet, they do not. Kensington should be ashamed for it's lack of support, and Mac users should seriously consider other options.
