If you move the Leopard dock to the side of the screen you get a dock with a gray background rather than the glassy surface. If you want that dock on the bottom of the screen as well, simply run the following:
defaults write com.apple.dock no-glass -boolean YES
killall Dock
This sets a hidden default on the Dock and then forces it to restart.
Any way of getting the glass on the side? even if it might look strange?
Um, any way to get rid of it? Just running
defaults write com.apple.dock no-glass -boolean NO
killall Dock
doesn’t. Should I just remove this line from com.apple.dock? This’ll teach me to hack what I can’t unhack…
Well, I just up-arrowed and entered it again, and it worked. Weird. Yes, I remembered to hit Enter and everything, but it still came up no-glass.
Well, independent verification (ahem…) confirms that running
defaults write com.apple.dock no-glass -boolean NO
killall Dock
DOES in fact reverse the effects of the above no-glassing code. Derrrrrr…
