# There are some hidden setting in Mac OS, the mouse scaling (mouse acceleration)
# is one of them. Disabling it is useful at sometime, you will know it when you
# play osu! (via Wine) on your Mac...
#
# This command will disable the mouse acceleration on Mac OS. To put it back to 
# normal, use '3' instead of '-1'. Also, to revert back to Apple default settings,
# you can just simpely open the Mouse pane of System Preferences and change the
# Mouse tracking speed to anything, then quit System Preferences.

defaults write .GlobalPreferences com.apple.mouse.scaling -1

# You should know that mouse acceleration != trackpad acceleration, to disable the
# acceleration of trackpad, use 'com.apple.trackpad.scaling' instead of 
# 'com.apple.trackpad.scaling'
