To prevent the Dock from appearing on mouseover:
Code:
defaults write com.apple.dock autohide-delay -float 9999999; killall Dock;
This adds a delay of 10 million seconds (about 4 months) between the cursor reaching the edge of the screen and the start of the animation to show the Dock. If the cursor leaves the edge before then, the animation is canceled.
You can also eliminate the Docks slide-in animation, so it appears and disappears instantly when you press the shortcut:
Code:
defaults write com.apple.dock autohide-time-modifier -int 0; killall Dock;
While Im mentioning Terminal command system tweaks, another good one is to enable text selection in QuickLook with:
Code:
defaults write com.apple.finder QLEnableTextSelection -bool true; killall Finder;
And of course you can reverse these changes with the following commands, respectively:
Code:
defaults delete com.apple.dock autohide-delay; killall Dock;
defaults delete com.apple.dock autohide-time-modifier; killall Dock;
defaults delete com.apple.finder QLEnableTextSelection; killall Finder;
