Snow Leopard Command Line Hacks

Here are my favorite command line hacks that enable special features or views in OS X 10.6 Snow Leopard.

• Enable Quick Look Folder Previews
  defaults write com.apple.finder QLEnableXRayFolders 1
  Once you’ve entered this command, restart Finder (killall finder or ctrl+option+click Finder Dock Icon, and Relaunch), select a folder, and hit the space bar.
• Enable AppleScript Studio Palette
  defaults write com.apple.InterfaceBuilder3 IBEnableAppleScriptStudioSupport -bool YES
  OS X 10.6 Snow Leopard allows you to work on AppleScript Studio Projects, but you can’t create new ones. Run the above command to add it back into Interface Builder.
• Disable Focus Follows Mouse
  defaults write com.apple.Terminal FocusFollowsMouse -string NO
• Confine Dictionary To One Window
  defaults write com.apple.Dictionary ProhibitNewWindowForRequest -bool TRUE
• Change iTunes Green Maximize Button Functionality
  defaults write com.apple.iTunes zoom-to-window -bool YES
  During the initial launch of iTunes 9, the green + icon on the window bar maximized the iTunes window instead of alternating to the mini player. Use this command line hack to enable this functionality once again.
• Automatically Play Movies in QuickTime X
  defaults write com.apple.QuickTimePlayerX MGPlayMovieOnOpen 1
• Keep QuickTime Full Screen While Switching Applications
  defaults write com.apple.QuickTimePlayerX MGFullScreenExitOnAppSwitch 0
• Disable QuickTime Rounded Corners
  defaults write com.apple.QuickTimePlayerX MGCinematicWindowDebugForceNoRoundedCorners 1
• Automatically Show Closed Captioning or Subtitles in QuickTime
  defaults write com.apple.QuickTimePlayerX MGEnableCCAndSubtitlesOnOpen 1
• Make List View Stacks Function Like Grid View Stacks
  defaults write com.apple.dock use-new-list-stack -bool YES
• Enable MouseOver Highlight in Stacks
  defaults write com.apple.dock mouse-over-hilite-stack -boolean yes
  Once typing in this command, restart Dock (killall dock) to view changes.
