It is implemented as a CFPlugin, and roughly implements the IOHIDServiceFilter.h interface. MacOS pointer acceleration is performed here in IOHIDPointerScrollFilter.cpp.

#Remove mouse acceleration mac driver

I am in the process of writing a DriverKit driver for the mouse. The driver is only compiled for Intel so doesn't work on new MacBooks. I have become accustomed to the Microsoft IntelliMouse acceleration curve.

#Remove mouse acceleration mac mac os x

and here's the programmatical variant, as I'll be trying to roll my own solution: Disabling mouse acceleration in Mac OS X SO

Before 10.4, there was a function to which you could pass your own acceleration curve which solved everything.īy the way, here is the Linux counterpart to this question: Disabling mouse acceleration in X.Org (Linux)

About every code snippet I found via Google.įrom what I've gathered so far, the only method to kill the acceleration curve seems to be to set the mouse scaling to a negative value (for which there are apparently two methods.) Unfortunately, this also kills the tracking speed.

Answers on this question: Make Mac OS X mouse acceleration more Windows-like.Mouse Acceleration Preferences Pane, the Snow Leopard version of which can get me close to a linear response, but at the cost of tracking speed (sensitivity).I'm not looking for any commercial solutions. I'm running Mac OS X 10.6.5 on a MacBook Pro. I've been at this for a long time, I'll probably have already tried the most popular answers. I like my touchpad acceleration and would like to keep it if possible. So far, I haven't found a way to get linear mouse response in Mac OS X.Īt this point I'm seriously considering installing another operating system.īut before I do that, or go hacking around OS binaries, maybe someone here has a solution? I've tried a gazillion programs and fiddled with every setting there is or there can be added. I've been looking for a solution to the unusable mouse problem in Mac OS X for ages.
