Kill Snow Leopard’s Blue Ring of Exposé

Looks like I’m not the only one who hates Snow Leopard’s blue ring around selected windows in Exposé.

Thankfully, we don’t have to live with such monstrosities. Here’s a quick fix to free yourself from the blue haze. Fire up Terminal.app, then:

1
2
3
4

cd /System/Library/CoreServices/Dock.app/Contents/Resources/
sudo mv expose-window-selection-big.png expose-window-selection-big.ugly
sudo mv expose-window-selection-small.png expose-window-selection-small.ugly
sudo killall Dock

This will disable the blue rings altogether, but you may want to replace these two images with some custom ones that look a little cooler instead.

Let me know via the comments or on Twitter if you find some replacement images!

***UPDATE***

My friend Doug provided some drop-in replacement images that are a huge improvement. Just drop them into the directory after renaming the default images. So after step #3 above, do:

4

open .

This will open Finder in the current directory. Now drag the replacement images into this directory, provide your password, and kill the Dock.

5

sudo killall Dock

Voilà!
