Speed up Mission Control animations in macOS Sierra
Here's a quick list of animation-related tweaks for macOS Sierra.



Don’t animate opening applications from the Dock

defaults write com.apple.dock launchanim -bool false


Speed up Mission Control animations

defaults write com.apple.dock expose-animation-duration -float 0.1


Remove the auto-hiding Dock delay

defaults write com.apple.dock autohide-delay -float 0


Remove the animation when hiding/showing the Dock

defaults write com.apple.dock autohide-time-modifier -float 0


Increase window resize speed for Cocoa applications

defaults write NSGlobalDomain NSWindowResizeTime -float 0.001




Once done, you'll need to killAll Finder &amp;&amp; killAll Dock to restart those programs.

You can find a lot more by searching for "dotfiles", and the source for the changes above (as well as many, many more) can by found in this particular dotfile by Mathias Bynens.
