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.
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.
defaults read -g com.apple.mouse.scaling
was helpful for me to see first that mine is set at 3. Unfortunately neither
defaults write -g com.apple.mouse.scaling -float 5.0` nordefaults write -g com.apple.mouse.scaling -float 7.0
seemed to have any effect, even logging out and back in after each. So I'm still looking for a free solution because the max mouse tracking speed is intolerably slow for a 42.5" monitor.
