After migrating to new Sequoia version, the dock cannot be moved to another monitor

@amiko, This worked!! thank you so much. Good workaround until Apple decide to actually acknowledge and fix it.

Side-by-side works for me, top and bottom is broken

After trying several different arrangements. It seems that the the only time that the dock can move to another monitor is when the laptop is not sitting directly between 2 monitors on top. I used to keep my Mac directly below the center of my 2 top monitors, and after the update, the dock failed to move to either of the top monitors. But if I now offset my Mac to sit directly under one of the monitors, then the dock will float to the top monitor opposite the one that the Mac sits directly under. The gap option also works but throws off a smooth mouse transition to the Mac below it. Also, side by side works as well, but for those of use that have arms for multiple monitors, that can be tough to rearrange. Here is the best configuration that I could find for my situation. Hopefully this will get worked out in a future update, so us users with this setup can go back to the original configuration.

Confirmed the workaround is to bump the main display up just a hair so that there is a small gap in between your macbook screen and the additional display that you have marked as "main" (The screen with the grey bar towards the top). Attached is a pic showing what I mean.

This Change really suck for us 3 screen users. The shot with the traditional 2 over 1 is how I have run for the last yr and almost alway keep my dock on the upper left as it sits in second scrn shot.

Now the only way to do that is to put the gap as some have suggested or as I have done here and move

the macbook screen to the right just to the point none of it is under the upper left(my primary) and the dock

lands there. This is the closest I can get to the previous "Natural" mouse flow in the previous OS versions.

better that the around the horn motion the gap method creates.

For those say that it never has worked on "seams" in this setup it DID. The Catch was the top screens Only

share Part of there Bottom with the Macbook below. This allows the mouse to bump the bottom and move

dock between all 3 screens. Yes the Dock was Partially on a seam but was anchored by the remaining bottom

that was not a seam.

Same for me! When the external display is aligned above the macbook, its not possible to move the dock there. Only if the external display is left, right or at the bottom.

I was having the same problem but after reading the comments I changed the arrangement of my monitors and now the dock will float to the monitor I'm using as it did before. See below for the arrangement that worked.

I can accept that as maybe you are using Mac since 50 years ago. 😂

Only 40. It's not possible to have been using a Macintosh for 50 years.

I don't know why level 9 user can say something like this :). Many of users said that this was a bug, even Apple bring it back the function in version 15.1. Wanna stand with your thoughts?

Just because there was a change, does not mean it is a bug. It is a bug only if the change was not intended.

I am fully aware of what the change was. The only situation that is different is when there are three displays.

This (with two displays) was NEVER possible:

This USED to be possible - assuming there was enough of the top left display area to "bump into the bottom" without crossing to the lower display:

This at present does not work. Is it a bug? I don't know. You and others think it is.

You can and should and probably have reported it.

If the change was unintended, then it will probably be reverted. If it was deliberate, then it is not a bug and will not be "fixed". Only Apple can decide that, not any of us.

I am a new in this forum just to report this bug, but I have been using MBP for about 12 years for developing software. But if you said that I'm a beginner, I can accept that as maybe you are using Mac since 50 years ago. 😂

I have been using a Mac since 39 years ago, a little less time than Barney 😎. The mac came out in 1984, and I happened to be one of the first people in my country, Portugal, to use one in 1985, and never stopped. There were a small number 128K and 512K macs at my university at the time.

I have only personally owned one for 30 years (I fondly remember my Quadra 840AV that I bought in 1994)

Barney has more eloquently than me explained how the Dock and Launchpad cater to users from other backgrounds, and how using just the keyboard with Spotlight is faster than reaching for the mouse or trackpad. I completely agree with him. My Dock is always on the side, and hidden. I never touch it.

A big waste of space in a small screen, a lot of wrist work to reach on a large screen.

I had my display set up in the Mac software the same way as you, SébastienK. To get my dock to appear on my external monitor when I move my mouse to the bottom edge of the external screen (without closing my MacBook Pro), I had to move the top bigger monitor in my Mac Display Settings to have NO overlap ABOVE the MacBook Pro monitor. So in my system settings I put my external monitor at the top right corner of the MacBook Screen in settings.

This functionally allows me to move the mouse from the MacBook Pro screen to the bigger external monitor by moving my mouse pointer all the way to the top right corner of the MacBook Pro, and the mouse cursor is just "funneled" into the big monitor.

Unfortunately, like yours, that big monitor's left bottom corner is about 6" to the left of the MacBook's top right corner. So it's a little jolting to have the mouse cursor jump 6" left and 2" up when moving to the upper monitor. In my screenshot, my ext monitor desktop is black because it's an OLED and I didn't want issues with burn-in.

update, macos 15.1 fixed 🎉

15.1 became public yesterday and I get the docks to show on all monitors now.

Can confirm this issue is fixed with 15.1. Apple listened!

On 15.1.1 here still experiencing the issue with Philips UltraWide monitor

With the Ultrawide monitor above the in-built monitor, move the mouse pointer onto the UW monitor and move over to the far left, then move down to the bottom until it stops. If the dock doesn't;t move to that monitor, tap the pointer a couple of times again on the bottom and it should move.

If the pointer moves down to the built-in screen you need to move it further left and try again. This is my setup to demonstrate. My top monitor is an LG UW unit.
