Ever found the magic mouse is moving too slow? Even you already move the speed preference to the most right? Here is how you can boost this little beauty, just paste the following to terminal:

defaults write -globalDomain com.apple.mouse.scaling -float 14.0

then loggoff, login, it’s done! The float number “14.0″ at the end, indicates the speed you want, if 14 is still slow to you go 16 or 999999 ^_^
