Disable mac mouse acceleration?

I've started playing Minecraft from time to time, but the pointer acceleration is extreme.

With an external mouse, the cursor should always move the same distance, no matter what speed.

However, I want to keep the pointer acceleration on the trackpad, as it is normally very helpful.
Can someone help me?

This should be done with http://www.usboverdrive.com/USBOverdrive/News.html, including other things such as scroll speed and acceleration, which can be adjusted (even individually depending on the application).

Shareware, so you can test it for free as long as you want. But if you are happy with it and want to use it permanently, you should buy a license to support the developer.

Can I separate the acceleration from the mouse and the trackpad?

Have not used it for some time, but that should be possible in any case. You can choose the settings either system-wide or individually depending on the input device and also depending on the program. But anyway, the program m.W. On Apple's trackpad or Magic Mouse, do not enter the controller.

Trackpad has its own setting like the mouse. System Settings Mouse - Pointer Motion.
