Dock not showing on external monitor

exactly the same here. Did update to Sequoia on my Macbook Air M1 end of September. And suddenly Dock not showing on external monitor anymore exactly the way hashtagrob has described it. Hope Apple fixes this soon. It is really a big pain to work this way. Currently I am on 15.0.1 (24A348) and it is still not fixed! Talked to Apple Support twice to address this issue. No solution yet.

The standard way to move the dock - the old way - by dragging the cursor to the bottom of the monitor in a multi-monitor setup no longer works in macOS 15.

The Dock has never been able to be placed on a seam between displays.

I have no idea if moving the Dock violated this setting in the past. If you were able to put it on the seam in the middle of two displays by moving it, that was probably a bug.

No, I understood completely.

Placing the Dock at a seam is not possible and never has been.

From what you and others say, moving the Dock to the upper display (putting it on the seam) from the lower display did work.

That appears to no longer work.

This is a straight up lie.

I've been using Sonoma until just a few minutes ago, and I have ALWAYS had my displays arranged vertically, external display above the internal display, because that's how they are set up physically.

Until just a few minutes ago, when the Sequoia installation finished, I have ALWAYS had a Dock at the "seam" between the two screens, i.e. at the bottom of the external screen, above the internal screen.

I remember how it annoyed me that I always had to move the mouse to one of the corners on the external display to get the Dock, and that the Dock would often vanish again while I was hovering over it to pick an app, because my mouse moved too far down and onto the lower internal screen.

It has DEFINITELY been possible for AGES to have the Dock between two vertically stacked screens, because that's what I did for the past couple of years.

Here's how it has worked as far as I'm aware. If you claim you can get the Dock at the bottom of the upper display, maybe Apple will put it back in an update.

Someone claimed you have to have a gap in the seam where one is smaller than the other. If that is required, I would have never noticed.

You could use the dock on the bottom of a screen that had a seam that didn't go across the entire monitor—for example, if the screens only half-overlap (only the side without the seam would bring up the dock). There is definitely a change in behaviour in Sequoia.

same here, on Mac Studio M2 Max. I have 2 screens, one on top the other.

just upgraded to Sequoia, and the dock only appears on the bottom screen, not on both.

(I have "Displays have separate Spaces" turned ON)

disappointing... totally kills my everyday workflow.

we have lost you there, you are confused. Apple does not allow any "overlapped" displays, nor is there any "seams" between displays. Displays are positioned edge to edge either vertically or horizontally, edges always touching. There's edge of one display touching the edge of another - not overlapping, and no "seams".

I'm a lot of things, but confused isn't one of them. My laptop was offset to the right of the monitor (which was above it). A mouse could pass between the two monitors only on the right of the bottom edge. On the left (which didn't line up with the laptop) you could move the mouse there and cause the dock to open.

Now, this may have been an error and not part of the design guidelines, but it certainly did work, and now it does not. I'm not new to this. I've had this setup since 2022. Like I said, I'm not confused.

I also can confirm that this no longer works in Sequoia 15.0.1. If my external monitor is stacked on top of my MacBook the dock will not show on the external screen. It has ALWAYS worked before. This really needs to be addressed ASAP? Does Apple even read these forums?

No, Apple does not read these forums, which are for user discussions only. Somewhere you can find a link to report a problem to Apple. I’m sitting in the sun with an iPad on vacation and can’t really see the screen will enough to search for the link.

The link has been posted multiple times in this thread already.

Oh... Sorry for bad answer

You did not understand the problem.
