How to Disable Drop Shadows from Appearing on Window Screen Shots in OS X 10.10 Yosemite

OS X defaults to including drop shadows behind window-centric screen shots (not full screen captures), but these can be disabled.

• Launch Terminal and insert this command:

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

• For immediately effect  of changes use this command:

killall SystemUIServer

 

 

•  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

• For immediately effect  of changes use this command:

killall SystemUIServer
