One of the lesser-known features of OS X is that if you right click on an app icon on the dock, you have the option to hide all of that app’s windows. While it’s great for when you’re trying to get things done, it can sometimes be confusing what apps are hidden and which ones are not, especially when you have a lot of apps running. This simple Terminal command can help fix that problem!
Simply type the following command into Terminal:
defaults write com.apple.Dock showhidden -bool YES; Killall Dock
As I have stated before, I recommend you type this into Terminal rather than copy and pasting it, as it gets you more comfortable with the command line.
Assuming you entered the command correctly, from now on, when an app is hidden, the app icon will be semi-transparent. This makes this much easier to quickly see what apps are hidden and which ones are not.
If you want to reverse the effect and bring it back to stock, simply replace the YES in the command with NO. As given below.
defaults write com.apple.Dock showhidden -bool NO; Killall Dock
