Mouse wheel scrolling function too sensitive with mouse wheels without distinctive clicks

The mouse wheel is extremely sensitive in Minecraft on OS X when using Magic Mouse (it's actually not a wheel, it's a touchpad on the mouse), I am using the number keys to switch between inventory slots, and am never using the mouse wheel, however, because it is very sensitive, it's possible to scroll it accidentally. There is currently no option to disable the mouse wheel, which could solve the problem.
