Magic mouse 2 moves very slow

Try this as a slow mouse fix. Works perfectly on all five of our Macs.

Address speed setting directly by using command line.

a. Using spotlight search (top right of screen), type in: Terminal and press 'return'.

b. Read - Copy the line following and paste it into Terminal and 'return'. View the tracking speed number returned.

defaults read -g com.apple.mouse.scaling

c. Write - Copy the line following and paste it into Terminal and 'return' (the speed setting will change to that of the number at the end of this line).

defaults write -g com.apple.mouse.scaling 5

3- Test the mouse to see if the track speed has changed. Revisit Terminal, click on it to ensure that you're in Terminal. Then arrow up/down (bottom right of keyboard) to select alternatively the Read and Write commands above. Change the number at the end of the Write line (1-99) and again test the track speed.
