I have an 11" Macbook Air + Yosemite with vertical dock.

The dock causes a large irritating shadow over any windows... enter image description here

I have tried these (found on various sites - reference Mavericks):

defaults write com.apple.dock hide-mirror -bool true; killall Dock
defaults write com.apple.dock showshadow -bool NO; killall Dock
defaults write com.apple.dock no-glass -boolean YES; killall Dock

The shadow remains after running all of these.

Is it possible to remove the shadow? (I do not want to disable any other effect - only the dock shadow).


  • I want to do the same but also didn't find anything yet. Did you find a solution in the meantime? – comfreak Dec 26 '15 at 11:24
  • No but the shadow seems less heavy in El Capitan – niico Dec 27 '15 at 0:42
  • for me it is still too much. I hope there will be a way to change it in the future. Till then all my windows need a "safe distance" to the dock ;-) – comfreak Jan 2 '16 at 11:07

I'm trying out cDock, and so far it seems to do the job.

  • Thanks - it's not clear how I would remove the shadow only? I'm happy otherwise with how it looks. – niico Nov 3 '14 at 8:29
  • I want to do the same like the creator of this question and I downloaded cDock. First it doesn't want to do its thing unless you deactivate Apple's new "rootless" feature which prevents system changes. But apart from that, I didn't find anything in the app that would let me change that shadow? – comfreak Dec 26 '15 at 11:23

Have you tried TinkerTool? It covers many such tweaks (although I have not checked for this one).

  • Thanks I downloaded it - can't see any dock shadow settings – niico Oct 21 '14 at 15:18
