How to make your Mac suck
I stumbled upon this one day, while navigating the inter-webs, and thought it worthy of sharing.Believe it or not, you can actually make your Mac suck. There’s a few effects you can use for minimizing your applications to the dock, but the “suck” effect is not available through the GUI in OS X. Instead, you must manually set it via Terminal.app:
defaults write com.apple.dock mineffect -string suck
Once you update that, you will need to restart the Dock service by either logging out or by forcing it to quit through Activity Monitor.
