External Display

Hello jakob_suehring,

Welcome to Apple Support Communities!

I understand from your question that you would like to have your dock on both monitors at the same time. I can certainly help you with this!

Unfortunately this functionality is not available at this time. You can only have the dock on one monitor at a time either on the left, bottom, or right side of the screen.

I hope this is able to resolve your issue. If you have any more questions or this does not resolve your issue, please reach back out on the thread!

Cheers.

You can set up your displays so that "displays have separate spaces" or so that they are mirrored, or so that they are combined into one "extended desktop".

When "displays have separate spaces", each display is its own little world, and the Dock needs to appear on each display when required.

If using Extended Desktop, each display is a part of a much larger Extended desktop, and the Dock will appear on the leftmost, rightmost or bottommost edge of the Extended Desktop, not the component displays. The Menubar will appear on the Primary display only.

That feature is available today, but it is somewhat convoluted. It has to do with Mission Control and multiple spaces.

You can create different SETS of applications working at the same time using Mission Control, and assign each SET to their own "space". You can then shift back and forth through different spaces using Mission Control.

The additional complexity and possible usefulness comes when you assign different spaces to different displays:
