OSX - Microsoft 3 Button mouse.

When using a windows build, you use shift, alt and crtl to change the view spin / pan when using the middle button (wheel.)
In OSX, power PC build, I’m only able to spin horizontally and pan. I’ve installed the Microsoft mouse driver but I’ve yet to find out a way to get OSX or blender to recognize the alt - middle wheel commands. Is there any way that I can configure either the mouse, OS or blender to use the mouse wheel like a windows machine? I’m really frustrated by not being able to spin my view when using the middle wheel.
For anyone who’s wondering, yes I’ve searched but everything is inconclusive. I’m hoping that a fellow MAC user will assist me so I can get to using my new microsoft mouse.
