Multi-mouse button mapping on OS X
This post was published 3 years 4 months 19 days ago which may make its actuality or expire date not be valid anymore. This site is not responsible for any misunderstanding.OS X users who happen to make use of a multi-button mouse may want to ditch the included software suite prepackaged with their mice in exchange for the $20 Shareware utility SteerMouse. After realizing that Logitech put very little effort into providing ample support for OS X users interested in utilizing their MX Revolution, I immediately sought refuge elsewhere.

SteerMouse supports a great number of multi-button mice including the aforementioned MX / VX Revolutions, MS Intellimouse, Apple Wireless / Wired Mighty Mouse, and many more USB & Bluetooth mice.
SteerMouse is incredibly resource friendly requiring roughly 2MB vs. Logitech’s 9MB while providing a little more flexibility. Map specific functions to individual buttons including keyboard shortcuts, cursor commands, profiles, application switching, and scrolling / paging up or down. Give the 15-day trial a test drive and see for yourself what this little mouse utility is capable of.
Make a note in the comments if the MX / VX Revolution was a complete pain in the side to connect out of the box on OS X. Oh the hoops I had to jump through in order to get this smooth rolling mouse to do what I want… Enough ranting and directions to create an entirely new post.
