Citrix issues with New MacBook Pro M1 chip

Hi all,

With apologies for following up on my own post, given it seems I’m alone in finding this issue, I’ll share the solution in case it is useful to others later: given that the dummy user account proved the issue was in my user profile, I changed my MacOS home folder do a different location, and copied across my important files (Documents, Music, Pictures). This essentially wiped my profile, which meant I needed to reset my System Preferences (and re-register for Apple Pay etc), but avoided the need to re-register the machine with Apple, reinstall apps and make new Time Machine backups, which would be required by a complete rebuild. This immediately fixed the issue, so I’m back up and running with all displays in full-screen.

Hope that helps someone in the future.

Best

I wanted to link this workaround I found on Reddit here if anyone was still looking (credit to u/theidealpancreas):

It requires EasyRes from the App Store (which is free) but so far it works great when I set the built-in XDR to 1728x1080; I can use full screen on both displays no matter where I initiate from plus it "removes" the notch all together in the sense that the main display does not go into the notch and just widens the top bezel. This seems to suggest it's more of a notch problem than an Apple Silicon problem and people can take from that what they will, but hopefully others have some luck with this workaround until there is a proper fix.

Also this is on 16" MBP so I can't attest to 14" MBP but I imagine it should work the same.

So I've managed to find a hack solution between all suggestions until Citrix do something about it.

After Grant's suggestion of unchecking System Preferences > Mission Control > 'Displays have separate spaces' (this needs logging out), I then dragged the Citrix window to the second monitor, clicked Enter full screen mode and was then able to interact with the MBP 14" display as intended.

System Preferences > Mission Control > 'Displays have separate spaces' wasn't so great by itself if you have different size monitor resolutions. (maybe I was doing something false here)

Here's my overview:

1. Citrix from MBP 14" > Enter full screen mode > second monitor not recognised.
2. Citrix dragged to second monitor > Enter full screen mode > MBP 14" display doesn't work as intended.
3. System Preferences > Mission Control > 'Displays have separate spaces' (this needs logging out)

Citrix dragged to second monitor > Enter full screen mode > MBP 14" display seems to work fine.

It's all a bit weird, but hope that helps.

I am also having this same issue, however I did figure out how to get multiple screens within Citrix to work, but still have issues. When you log into citrix on your macbook screen, before you maximize the Citrix, drag it to the new external screen, then enter screen into "enter full screen" mode. That will utilize two screens. Now, the problem is an alignment issue and a phantom bar at the top of one of the monitors that does not allow you to grab applications (like adobe or a microsoft office application or web brower) and drag to the other screen. The alignment seems to be off by a quarter of an inch and I do not know how to get it to align properly. I've messed with the displays function in the system preferences and nothing seems to work.

I had no issues with my older 2011 mac and citrix. However, with the 2021 Macbook Pro with Monterey (12.0.1) and utilizing Citrix version 21.11.0.16, the alignment is off for some reason, which basically makes the second monitor useless still.

I'm guessing this is a Citrix issue? Maybe a little of both?

This worked for me as well with EasyRes, so thank you! I do, however, only find that the resolution of 1800x1125 120Hz on the MBP screen works. With any other, there is still an alignment issue. I have two external screens and they work just fine, but I have to keep the built-in screen from the MBP with the resolution noted above. The font is very small, but it’ll do for now.

Thank you for this find JSF!

Have you made certain that the Arrangement pane reflects how your displays are on your bench, left right up down?

DON't use Full screen. It is a feature reverse ported from the iPhone, land of tiny screens and one-at-a-time processing. Avoid 'FullScreen". It is bizarre with multiple displays. instead, stretch the window until it is quite large, but short of Fullscreen.

In my opinion, the issue is Fullscreen. In my opinion, that feature has NEVER worked right with more than one display.

If you stretch the widow manually to very large, but avoid clicking the Fullscreen button, I expect it will work fine.

MacOS Monterey 12.1 released today Monday 13 Dec 2021 may have some fixes around "the notch".

What about your preference to "FullScreen"? that feature works really badly on the Mac. Are you using FullScreen?

There are a few Applications that deliberately defeated Extended Desktop for performance reasons. Older versions of iMovie was one. Rather than opening multiple windows, it opened ONE window with multiple regions, and those regions could not be moved to a different display.

Whenever you ask ME about Fullscreen use with multiple displays, in my opinion, it does not work. When it was first released, the secondary screen went completely BLANK when Fullscreen was invoked. It appears to have improved, but not much.
