How to Fix Grayed Out/Transparent Icons in Dock – Mac OSX




I just recently re-installed OSX Snow Leopard 10.6 on my 2007 15″ Macbook Pro Core 2 Duo. After installing all my programs and customizing the dock, some programs were grayed out or semi-transparent (like Firefox or Word) and others weren’t (like iTunes or Safari). It was driving me nuts because I couldn’t figure out what the problem is. My dock looked similar to the screenshot below.

Thanks to TUAW, I found how to fix the problem. Its a simple fix that can be done in the Terminal. Its a matter of turning on or off the dock’s transparency.

Step 1

Open the Terminal.app under Applications > Utilities. Then you can copy and paste the following command:
defaults write com.apple.Dock showhidden -bool NO You can also use “YES” in place of “NO” to turn transparency on.
Then put in
killall Dock
to reset the dock. It will go away and refresh.

Step 2

Now, if you still have a few grayed out/transparent icons, drag them off the dock to remove them. Then drag them back on from your Application folder. They should now all be not transparent. That’s it!
