| Disable Dock Autoshow Delay | |
| I hide my dock to maximize the usable area of my screen. By default, there’s a short delay on the autoshowing dock animation. This removes the delay: | |
| defaults write com.apple.Dock autohide-delay -float 0 && killall Dock | |
| Show the Library Folder in Finder (Lion and later) | |
| In Lion and Mountain Lion, the Library folder is hidden from view. This will make it appear in your home folder again: | |
