Make Hidden Apps Transparent on Mac OS X
I love this hack, and I always miss it on a newly installed Mac.
This code snippet makes the icons of hidden applications semi-transparent. This makes it a lot easier to understand which applications are currently hidden.
The change will be visible in the Dock and in the fast app switcher (the thing shown when hitting cmd + tab).
Open Terminal and write these two lines:
defaults write com.apple.Dock showhidden -bool YES
killall Dock
That’s it.
To revert the changes, write the code above but change “YES” to “NO”.
