MacOS – Change the mouse wheel scrolling acceleration

macosmousescrolling

I am new Mac user and I don't really like the Magic Mouse so I reverted to a good old 3 button mouse with a scroll wheel.

When I turn the wheel slowly, it only scrolls pixel per pixel (or per two pixels)
If I turn the wheel more quickly, it scrolls nearly line by line. There is a kind of scroll wheel acceleration where the amount scrolled for each wheel step depends on the rotation speed of the wheel.

This behavior is not present in Windows where you always scroll a few lines per wheel step.

Is there a way to disable this behaviour or to tweak it in Mac OS X Lion?

Hope you're still reading - I highly recommend one of the third party mouse managers like SteerMouse or USB Overdrive or ControllerMate.

I found the arch of the Magic Mouse just too low and went back to the old reliable Logitech MX Revolution, but I will never install Logitech software again without an excellent reason. These packages will let you configure all of the buttons and SteerMouse (haven't verified for the other two) will definitely let you specify linear or accelerated wheel scrolling with variable degree of acceleration.
