Looks like [I’m not the only one][1] 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:

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][2] if you find some replacement images!


[My friend Doug][3] provided some [drop-in replacement images][4] that are a huge improvement. Just drop them into the directory after renaming the default images. So after step #3 above, do:

open .

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

sudo killall Dock
