Show Mac dock on all screens

So I have bought the new 15" Macbook Pro and two LG Ultrafine 5K montors and I really enjoy the setup. But there is one ting tha is disturbing. I have set up separate spaces on all three screens, but the Dock only shows up on my laptop screen. And its annoying when whoeking on the big screens in highest resolution.

In my previous setup with a iMac and two older Apple 22" monitors I had the Dock on all screens (Sierrra). But not now. Have anyone out there the same problem or a sollution?

Best regards

You can get the Dock to appear on any single monitor of a multiple monitor setup, but with a caveat.

Since all displays form a single virtual display surface, there is only one "Right" and one "Left" but multiple "Bottoms" if the displays are organized horizontally from left to right. If you organize them vertically there are multiple "Left" and "Right" but a single bottom. Not sure what will happen if you form some sort of "L" shaped pattern as I only have two monitors in my setup - would guess that the rule still holds but unable to verify - perhaps OP can verify with his triple monitor setup?

Unfortunately, only the horizontal Display layout and the "Bottom" Dock setting will allow the Dock to migrate to whichever screen bottom you place the cursor at (takes a second or two for the Dock to appear on the new monitor). So if you have a horizontal arrangement (which you can change in the Displays System Preferences pane) , select "Bottom" for the Dock location in the Dock System Preferences pane, and if you move the cursor to the Bottom of any of the monitors the Dock should appear there in a second or two (I verified this in a two monitor setup - so hopefully OP can verify this in a three monitor setup).

If you have a vertical arrangement, selecting either "Right" or "Left" for the Dock location in the Dock System Preferences pane, and the Dock DOES NOT MOVE to the corresponding monitor edge you move the cursor to - inconsistent and a BIG BUMMER.

This has been the case for quite a while - at least since Yosemite (I verified on a Yosemite two monitor setup also).

I learned this from the article at http://www.techradar.com/how-to/computing/apple/how-to-use-the-mac-os-x-dock-on- all-monitors-1311709

Good luck...

Given your three monitor setup I think you discovered a way around the vertical setup limitation I talked about earlier. If you set the dock to appear at the "Bottom" and move the cursor to the portion of the screen of any of the three monitors that is NOT shared, then the Dock should appear on that monitor.

So in your three monitor image case you have above, the dock should appear in leftmost monitor if you place cursor in the lower left corner of it. If you place cursor on lower right corner of rightmost monitor then dock should appear. And if you place the cursor anywhere along the bottom of the lowest monitor then the dock should appear.

This "theory" is based on setting my two monitors in a slightly offset vertical arrangement where there really is multiple "bottoms". Still no luck on putting Dock on either right or left and having it appear on anything other than the monitor that has the Toolbar associated with it (top monitor in my case). Here is what my test setup looked like:

So given this additional insight does your setup work this same way when you have Bottom set for Dock location and try seeing if the dock appears on each of the three monitors in the same way?

Good luck...

No, I dont need it so often, I use QuickSilver for fast launch and command-tab to switch. But I was curious why Dock didn't work as I was used to, in my new setup.
