Dock not showing on external monitor

(in response to Barney-15E)

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.

This is the issue.

Used to work up until (including) Sonoma.

Doesn't work anymore in Sequoia.

Regression.

Simple.

Doesn't matter to me if you believe it or not.

What is this talk about "seams?" This isn't a shirt we're talking about. The simple fact is that prior to Sequoia, there was a dock in whichever display the cursor was in—that's two docks for persons using two displays. It wasn't straddling a "seam," but for many, was at the bottom of the active display. Now, under Sequoia, the dock that used to be on the second display is no longer there. Gone. Disappeared, Missing. This bug is as simple as that.

This is also happening to me.

Macbook Air M3

macOS Sequoia 15.0

When I hover to the bottom of my monitor, the dock will not appear on the desktop of my external monitor.

But I notice that will happen only when the monitor is arranged above my MacBook on the Displays > Arrange menu.

When it is arranged beside (either to the left side or right side) of my MacBook, then the dock will appear as usual.

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.

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?

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.

there is no "seam" between two displays. Please use proper wording while describing the issue, you've confused a lot of folks with your "dock positioned in the seam" =)

The situation is that before Sequoia it was possible to have dock show on either display by hovering mouse over the bottom edge (if dock is configured to be at the bottom, and also worked even with dock auto-hide option enabled). Since Sequoia you cannot see the dock on secondary display no matter what you do.

Once again, you have no idea what this thread is about. You are not running Sequoia on a Mac with two or more displays, and you don't know what you're talking about.

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.

If the monitors were placed so (for example) they had a partial seam you could bring up the dock by mousing-over the section without the seam. This is a change of behaviour in Sequoia which means that if any part of a seam is on that edge, the dock will not appear.

Thanks, you've perfectly described the issue. Plus, i have two external monitors, one in office and another at home. Both of them fall into this issue. And even one of them are studio display, so I don't think it is a software issue among 3rd party hardwares, it is simply a Macos15 bug.....

Hope apple can resolve this asap

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.

You can search the archives. It has always been not possible to set the Dock to a middle position.

If you have the displays set with one above the other, when you set the Dock to Bottom, it will go to the bottom-most display. If you set them left or right and set the Dock to Left or Right, the Dock will go the far left or far right of the two displays.

With displays set side-to-side, setting the Dock to Bottom will allow you to move the Dock between the displays.

As I stated, if you were able to Move the Dock between the displays after setting it up, it appears that is no longer possible.

That's why it violates Apple's user design guidelines. You can overshoot your target easily. They may have removed the capability or the engineers failed to implement it on the rewrite.
