Mouse acceleration in OSX

I doubt it. I think the mouse acceleration is part of the operating system. I recommend that you uninstall all third party mouse software. You might like it better. If you don't, might be that the many third party utilities you've installed are interfering with each other. Make sure you're only using one at a time.

Also, please consider a trackpad instead of a mouse. Macs really shine with trackpads...using the computer with a trackpad is far better than with mouse, because you can use gestures.

 

First let me say that I've spent little (next-to-nothing) time using PC's running Windows.

But -- in the time I have spent -- one of the first things I noticed was that "mouse handling" in general just "feels different" in Windows, than it does on the Mac.

This is less a "function of the mouse hardware", than it is of the OS itself.

Questions:
Have you tried any OTHER mice on the Mac?
Do they seem to be having the same problems?

My guess is that you're going to see similar "differences" in handling with ANY mouse that you switch between Windows and the Mac OS.

It's "in the OS" -- NOT the mouse....

 

Do you mean, not as comfortable/ergonomic as the original Magic Mouse?

I ask because whilst I loved the behaviours with the OS of the original, I found it not suitably comfortable.

 

"Mouse lag" is known issue with some Macs.

Maybe try an app like this:

The Apple Mouse is the best mouse for the Mac in every way... except comfort. It's about the most uncomfortable mouse by any manufacturer for any platform.

 

If I stretch things to include Apple's first USB mouse: I found it comfortable. I still do, when I use one, but that's infrequent.

 

and don't get me started on those horrible iMac keyboards...
