Disable the Window Shadow on Screen Shots in Mac OS X

Ever noticed that there’s a shadow on every screen shot of a window you take in Mac OS X? You can easily turn this off by using the command line:

defaults write com.apple.screencapture disable-shadow -bool true

You’ll then need to restart SystemUIServer by killing it:

killall SystemUIServer

Now take a screen capture of an individual window using Command+Shift+4 and the screen shot will not include the window shadow.

If you want to revert back and have shadows on individual window screen captures again, use:

defaults write com.apple.screencapture disable-shadow -bool false

And again kill SystemUIServer for changes to take effect.

Two other nice screen capture tweaks include changing the screenshot image file type and changing the save location of screenshot files which helps you reduce desktop clutter.
