Not sure how you guys feel about mouse acceleration, but personally I hate it. If you want to disable it in OS X macOS then I've found the small utility SmoothMouse does it very well. It adds a tab to system preferences with settings to enable/disable acceleration and change tracking speed.

It allows you to specify whether acceleration is on/off for mouse and trackpads (you can set individually)

I've not noticed mouse acceleration.  What are the benefits and pitfalls of disabling it?

When you disable it the computer doesn't try to 'optimize' where your mouse is going. It simply moves your mouse exactly as you move it. For trackpads, I don't mind acceleration as they are often much less accurate than a mouse, but when using a mouse I find mouse acceleration annoying.

I would recommend downloading the tool and then toggling it off/on. I find the difference quite apparent.

That's cool. I just grabbed it and will try it out. I'd also like to get a sense of what the difference feels like because I honestly don't know. I've never messed with it aside of leaving it at default in whatever might have an option to change it and just adjusting tracking speed to suit myself when I felt the need.

Thanks for sharing this.

I'm one of the few who prefer mouse acceleration in games, for the same reason I prefer it in the rest of the OS: move quickly = move at larger distances and move slowly = be more precise. I don't see why this should not apply in games, even FPS.

In games I dont like it. Throws me off.

On desktop, I dont mind it so much, but...

In OSX, and this has bugged me ever since OSX, is the mouse has this odd 'pothole' when moving slowly. It goes from moving smoothly slower and slower, then hits this grove and goes insta slower. Its done this with every dang mouse I've tried in OSX ever since OSX started doing it. Theres no way to free-hand draw a smooth spiral to a center point with the OSX mouse driver.

I wonder if that smoothmouse gets rid of that... hmm.
