I have been trying to increase maximum tracking speed for my 2018 Macbook Pro trackpad past the normal settings for Mac OS Mojave 10.14, but I am unsuccessful. enter image description here I have looking at the previous answers, but they only apply to Mac OS High Sierra. I have tried the following commands in Terminal:

defaults write -g com.apple.mouse.scaling -float 5.0

defaults write -g com.apple.trackpad.scaling -float 5.0

It seems that the names of the files have changed so I am unable to change the correct ones.


The app SteerMouse has multiple adjustments for tracking speed and acceleration, which go beyond the limits imposed by the macOS controls. I've used it for years to resolve the same complaint. SteerMouse 5.3.8 works happily on Mojave.
