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

Your image shows how it has always worked. It doesn't matter which is the primary monitor. You can't place the Dock on a seam between displays. That would violate Apple design guidelines as you could easily overshoot the Dock and have to play whack-a-mole moving back and forth. That's why the menu bar is at the top of the screen and not on top of windows.

Imagine a large external display situated above a laptop - you're working primarily on the external display as it offers increased real estate, but now have to move your cursor all the way to the very bottom of the laptop screen to change between apps by clicking their icon on the dock. It's incredibly frustrating, especially when it's been possible up to this point to have the dock move between displays easily to suit your workflow.

Before somebody suggests using cmd+tab to switch between apps, I'm left handed and use a WACOM so that isn't a viable option. The dock can switch between screens if they're side by side, so why not above and below, as before?

I think the only way to leave the space is if you have 3 monitors (mac + 2 external). I had to place the bottom monitor just touching the edge of the monitor to the top left... otherwise I cant add a space.

Well, I missed this function as well. I don't know that some people just mentioned if this behavior is by design should be like that. However, I can confirm that this function was working well before Sequoia.

The good news is some Redittor confirmed that the function was fixed in version 15.1 🥳.

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?

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. 😂

How did you leave a space?

Same issue. I found a decent workaround.

When you "arrange displays" leave a little space between the macbook on the bottom and the main monitor on top. That fixed it for me.

Worked in every Version before.

No, it didn’t.

There’s apparently a fix available but Apple hasn’t released it yet. 

There also another bug that prevents iMessage from working when VPN is on. 

This is really shoddy rollout from Apple. 

@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.

I can kind of understand the logic behind what you're saying, but up until Sequoia the dock has absolutely been able to sit on the 'seam' between displays and overshooting it has never been an issue - I've been using it in this way for at least a decade now, if not longer. It just seems like an odd piece of functionality for Apple to remove, but it isn't the first and won't be the last, I'm sure.

Regarding your cmd+tab comment, yes I use both hands to type, but it's difficult to use a key combination that requires your left hand when you're holding a WACOM stylus in your left hand (hence noting that I use a WACOM and am left handed). There's no tab button on the right hand side of my keyboard for my 'spare' hand to utilise.

Ok

For those who have managed to add the 'gap' between displays, how have you achieved this? My displays want to sit flush with each other when arranging them - is this something that is only possible if using three displays, rather than just two?

Yes, it requires three displays. If you have only two displays, you can't leave a gap, otherwise your cursor would be stuck in one the displays and not reach the other. Note that with three displays, each display still needs to touch at least one of the other two.

In the configuration below, for example, you can put the Dock at the bottom of display 2, but not 1; and if you want your cursor to go from 2 to 3, you need to move through display 1, as 2 and 3 are not adjacent:

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.
