I like to send the command, control and other system keys to hosts that I’m using ScreenSharing or Remote Desktop to access. But as I recently discovered, not everyone does. You can turn this feature off using the defaults command to augment the DoNotSendSystemKeys key of the com.apple.ScreenSharing.plist property list file. Simply run the following command: defaults write com.apple.ScreenSharing DoNotSendSystemKeys -bool YES To turn them back on: defaults write com.apple.ScreenSharing DoNotSendSystemKeys -bool NO Or for Remote Desktop, augment the com.apple. defaults write com.apple.RemoteDesktop DoNotSendSystemKeys -bool YES To turn it back off for Remote Desktop: defaults write com.apple.RemoteDesktop DoNotSendSystemKeys -bool NO FYI, if you don’t want to send the command keys…
