I've just updated to Mavericks, and while I like having the dock on my 2 Landscape displays, my third portrait display is entirely unsuited to having a dock on it.

How can I suppress the dock from appearing on one of my 3 displays?


I can't find any way to allow the dock on 2 of the 3 displays.

But, there are some things you might do.

In Mavericks, the default is that each monitor has its own Space, an Apple way of saying that each monitor is its own independent desktop.

The implications of that are that your menu bar will be on all monitors but "disabled" on the monitors that you are not currently focused in. It also means that the dock will automatically change to the monitor that you are focused in.

You can change this setting so that the monitors are one Space, or one desktop. In "System Preferences" > "Mission Control", deselect the box for "Displays have separate Spaces".

Now, your menu bar and dock will only appear on one screen and will not move automatically.

To change which monitor is your primary monitor, go to "System Preferences" > "Displays". On the monitor that is your current primary monitor, a tab on the top of the window will say "Arrangement". There will see the side-by-side layout of all the monitors. Click and drag the white box on the top of your primary monitor to a different monitor to change which is your primary.

The new primary will have your menu bar and dock.

  • How on earth do you drag the dock from one monitor to another? I can't figure out a way to do that... – Jonathan van Clute Apr 9 '14 at 17:19
  • Sorry about that, looks like things have changed. I'm going to update the answer. – Joseph Hansen Apr 9 '14 at 17:29
  • Aha... ok thanks for that. Unfortunately I specifically don't want to lose the multiple menu bars, but having the dock on my 3rd screen is seriously frustrating. It looks like there is no way I can "win" here. The multiple menubars and iCloud Keychain were the only practical reasons for me to upgrade to Mavericks anyway... so I might just have to stay with Mountain Lion after all. – Jonathan van Clute Apr 9 '14 at 17:44

Note: This assumes you have "Displays have separate Spaces" turned on.

The Dock only appears on one display at a time. To move it between displays, simply hold your mouse pointer at the bottom of the screen you want until the dock appears.

(The screen with the Dock on it will also be the one with the ⌘⇥ app switcher.)

  • This is not at all what I was asking for in the original question. The entire point was to not have the dock ever appear at all on one of my displays. – Jonathan van Clute May 15 '18 at 15:19
  • Do you mean you want it to be impossible to make it show up? It shouldn't be showing up anyway unless you tell it to, but I don't know how to stop it from ever showing up at all. – SilverWolf May 15 '18 at 15:41
  • Yes, the problem is I like my dock to hide itself when not in use and no matter which edge of the screen I choose I will always end up unintentionally making it appear just when I don’t want it to. This is why I wanted to completely prevent it from appearing on one of my screens, or even better appear on only one screen just like it used to. This is a moot point now because I have gone back down to just a single display on this machine. – Jonathan van Clute May 15 '18 at 15:43
