Solved by installing OS X 10.9 (Mavericks)
Scrolling around the hotbar was performing oddly.
When I scrolled with my mouse wheel or two fingers with my touchpad, I expected just the selected hotslot (on hotbar) would change.
When I scrolled with my mouse wheel or two fingers with my touchpad, not only did the hotslot change but also my view "scrolled" up and down or left and right if I scrolled left and right on my trackpad.
Steps to Reproduce:
1. Open a minecraft world
2. use a trackpad or mouse wheel to change the selected hotslot

Okay, fixed it. Everything is working normally for me.
Confirmed, weird behavior seems like a LWJGL bug.

Same bug for me as well. ๐

It is still a bug as of 1.6.2

Same Bug on OS X 10.7.5. Seems that the multitouchmouse (magicmouse from apple) is recognized as a touchpad. But Touchscreenmode is OFF

I also noticed it raised my view when I used my Logitech mouse for my Mac with TouchScreen Mode off.

same on OS X 10.9 (13A524d) on Minecraft 1.6.2

LWJGL already fixed the issue in a nightly build, waiting for an actuall release: https://github.com/LWJGL/lwjgl/issues/42

Has there been any fixes/updates to this? I've been on 1.6.2 and it updated recently again and I came across this problem for the first time. I am using a magic mouse from apple. The link above just says it will be fixed over a month ago.

I'm guessing that nightly build of LWJGL has been made into a stable release yet, or Mojang has not pushed it to the launcher.

This seems to be an OSX problem. I switched from using the Magic Mouse to a Razer Taipan and it made no difference with the scrolling. And it works perfectly fine on my Windows computer.

Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.2.8 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Does updating to OS X 10.9 (Mavericks) resolve the issue ?

Yes. This issue has been resolved with the OS X 10.9 update, running Minecraft 1.7.2/ Launcher 1.2.8. Thank you for your continued support.

Thanks for the feedback.
For me, the view moves but the hotbar does nothing.Never mind, my trackpad isn't currently working.
