Lightroom Classic Secondary Display Problems with Mac OS multiple desktops on external display

On Mac OS you can have multiple desktops and change between them. When an external display is connected to an Mac Book you can set the external desktops to be independent from the on on the internal desktop. So when you change the desktop on the internal display, the desktop on the external one stays. Unfortunately Lightrooms second display does not work well with this setting. I have Lightroom's Main Window on the internal display of my Mac Book and the second window on the external display. When changing the desktop on the internal display Lightroom secondary display automatically disappears on the external desktop. It moves to the desktop on the internal display where the Lightroom main window is open.

To move Lightroom's secondary display back to the external display I need to go to Lightroom Settings set the secondary display to be shown on the internal display and then change it back to the external one.

This effectively makes the secondary Lightroom display pretty useless to me. Other photo software like PhotoMechanics work perfectly with multiple desktops and displays.

Please fix this problem.

You don't refer to your "Mission Control", settings, which is the System Preference that controls multiple "Spaces" (Apple calls them Spaces, not Desktops). I don't use multiple Spaces, I find with 2 screens (and Com-H to Hide apps) I don't need to use it, and it makes for more complexity than I want. Also, I never run into your issue. Some people see a feature and can't help but use it, and, as a Mac Geek (and 25 year IT Pro) I understand your desire! Perhaps you have separate Spaces for separate work?

Regardless, I always have the Mission Control setting "Displays have separate spaces" as OFF, which I read can help reduce the complexity. Is this what you have? Try it and see? You may just be trying to juggle too many balls, it's neither Apple's nor Adobe's fault, it's just the way LRC is written.

I would EXPECT the "secondary display automatically disappears on the external desktop" to happen, since LRC's no longer the active app. It doesn't seem like a problem that Adobe needs to spend tens of thousands of dollars to fix, for one or two users.

I have "Displays have separate spaces" as ON. It suits my workflow better.

I would EXPECT the "secondary display automatically disappears on the external desktop" to happen, since LRC's no longer the active app.

In PhotoMechanics it works as expected. Whatever space I switch, the other window remains in its place.

I've been using LR with multiple displays since Apple killed Aperture, on:

2011 MacBook Pro

2011 iMac

2012 Mac mini

2015 iMac

2015 MacBook Pro

Using Sierra, High Sierra, Mojave, and Big Sur (I skipped over Catalina.)

And rarely have issues with the second display. There are some design problems but otherwise its been reliable. Maybe something in your environment is different?

Thank you for your comment. Good to hear, that you have no problems.

Do you have "Displays have separate spaces" activated in System Settings?

I will soon get a new Mac and set it up from scratch so I will check if that helps.

Displays have separate spaces is always unchecked so I don't get double menu bars.
