If you’ve upgraded to OS X Mavericks, you’ve probably noticed that the dock is less translucent than it was in OS X Mountain Lion. If you prefer that look to the new look, here’s a quick tip that will make the Mac dock translucent in OS X Mavericks.
All you have to do is open Terminal and type in the following command:
defaults write com.apple.dock hide-mirror -bool true;killall Dock
Your dock will disappear for a few seconds and reappear up with a new translucent look – so much that you’ll be able to see your wallpaper right through it.
To reverse this and get the original dock back, enter this command in Terminal:
defaults write com.apple.dock hide-mirror -bool false;killall Dock
As you can see from the above image, it’s not a huge difference, but enough that it’s noticeable. Which look do you prefer?
