As stated earlier, it is an issue effecting a lot of mice. Not just Apple mice and OS X. All mice without distinct clicks on the wheel or a touchpad instead of a wheel are effected. Even Microsoft is producing mice with a touchpad for scrolling.
This is no niche issue!

To disable scrolling in the OS is not a solution.

Sometimes a solution is to adopt to new/changed hardware to make life more convenient for the user.

I can't update the affected versions as this ticket is marked as resolved.
It is sill an issue, though.

Furthermore, there are a lot more mice (and trackpads) affected by this now. Just search for "mouse touch scroll" on Amazon. Many mice now use a touchpad for scrolling which lacks the clicks many mice use for their wheels. Also there are mice with wheels that lack a distinct click. Using these devices it is also hard to switch to the next item.

This is no longer only an OS X issue!

The solution this ticket asks for is an option to simply ignore the scroll input. Mouse buttons are already configurable. This shouldn't be a hard problem to solve.

Still a concern in 14w29a/b.

An option to disable mouse scrolling or assign keys to prev/next item would be greatly appreciated.

PS: This has been reported several times in the past (e.g. MC-4657, MC-31061 an more) and has sometimes been closed as a feature request.
To the affected users the way too sensitive scrolling behavior in Minecraft is a bug, as other applications and games (e.g. Kerbal Space Program) behave just fine when scrolling using a Magic Mouse.

This is also true for any trackpad or mouse with touch scrolling or mouse wheels that don't click while scrolling. The user can't predict how far to scroll using touch input, while a clicking mouse wheel makes this easier.
