Speed up Mountain Lion

Some useful commands too speed up Mountain Lion I came across:

Disable smooth scrolling:
defaults write -g NSScrollAnimationEnabled -bool NO

Disable rubber banding (Sadly doesn't work everywhere, applications will need to restart after):
defaults write -g NSScrollViewRubberbanding -int 0

Reset rubber banding:
defaults delete -g NSScrollViewRubberbanding

Speed up the Dock animation:
defaults write autohide-time-modifier -float 0.40;killall Dock

Reset Dock animation:
defaults delete autohide-time-modifier;killall Dock

2D dock, because the indicators on the new 3D dock are absolutely impossible to see:
defaults write no-glass -bool true


That said, last year I posted some Lion commands that still work too :)

Speed up Mission Control, by reducing the length of animations and reduce the delay before switching spaces:
defaults write expose-animation-duration -float 0.15
defaults write workspaces-edge-delay -float 0.15
killall Dock

You can modify the 0.15 to whatever you want, but this is my preferred settings.

Remove mouse acceleration (needs a relog):
defaults write .GlobalPreferences -1


Alternatively, you can have a look at this configuration file which is a nice collection of useful tweaks. Most of htem are pretty harmless, but it also contains some rather agressive ones I wouldn't want to touch (like turning off auto-quarantaine of downloaded files!).
