MouseWorks for OS X is a driver for Kensington input devices running under Mac OS X. It provides enhanced acceleration, scrolling support, and configurability for Kensington's current USB and ADB mice and trackballs, plus one-touch access to favorite Web pages and applications using the DirectLaunch buttons on Kensington's Turbo Mouse Pro trackball. The MouseWorks control panel, featuring a new Aqua interface, provides easy access to all settings.
The mouse and software work perfectly with my MAC OSX 6

Pros
The programmable buttons on the side are a great convenience as the ability to have a feature when clicking both top buttons at once. You can cut, copy, paste, double click, open an application or almost anything your heart desires.
Cons
There are none that I have found.
Summary
The feel and feature set of this mouse make it the best most versatile I have ever used. Period!
pretty good

Pros
Took a bit of getting used to, but I like it. Especially being able to program use of a 2nd button (new for a Mac user) and combo buttons for 3rd function -- I used 2nd for drag&drop function and two together for scrolling up&down in a window. I like ability to set speed of cursor (arrow) movement on the page so fine movements are slow while longer distance movements are fast. Therefore I don't have to scroll and scroll and scroll to move a long distance across the screen.
Cons
I wish I could scroll horizontally as well as vertically, like the current Apple Mac supermouse will do. I have that at work and am used to it and was surprised not to get it on this new mouse. That's actually the reason I bought this new mouse... Do you have horizontal scroll for windows and not Mac???
