How to increase "tracking speed" beyond the maximum? For a Macbook Pro, I've set trackpad settings for Three Fingers to "Dragging":



However the tracking speed is too slow, and often it's impossible to drag for a larger distance due to the size of the physical trackpad.

How do we increase the tracking speed beyond the maximum allowed?
The value of the preference is stored in ~/Library/Preferences/.GlobalPreferences.plist and can be changed with something like defaults write -g com.apple.trackpad.scaling -float 5.0. The normal maximum value is currently 3.0. Applying the changes requires logging out and back in.
