Making Hidden Apps Appear Faded Whilst Sitting On The Dock? Sometimes it can be quite difficult for me to tell which of my apps are hidden on the dock and which are not. Is it possible to make those Apps which I have hidden (either by terminal command or otherwise) to appear as those they have faded into the background whilst sitting on the dock ie to have lowered or reduced opacity.
You can use the following Terminal command:

defaults write com.apple.Dock showhidden -bool YES &amp;&amp; killall -HUP Dock


This can be undone with…

defaults delete com.apple.Dock showhidden &amp;&amp; killall -HUP Dock
