Parallels Desktop 26.3.3 crashes when entering Full Screen on macOS 27 beta

[Bernice1]

Hi Parallels team,

I am experiencing a reproducible crash with Parallels Desktop on macOS 27 beta.

Environment:
- MacBookPro18,2, Apple Silicon
- macOS 27.0 beta, build 26A5353q
- Parallels Desktop 26.3.3 (57507)
- Windows VM

Issue:
Parallels Desktop works normally in Window mode. However, when the VM enters Full Screen, or when it auto-starts into Full Screen after loading, Parallels Desktop crashes.

Workaround:
Setting Startup View to Window prevents the crash. Full Screen consistently triggers the issue.

Crash details:
- Process: prl_client_app
- Exception Type: EXC_CRASH (SIGABRT)
- Termination Reason: Abort trap: 6
- Crash stack includes:
NSMenuBarPresentationInstance
_setBaroloFullScreenModeUIMode
_setPresentationOptions

This appears to be related to macOS Full Screen / menu bar presentation handling. Could you please confirm whether this is a known macOS 27 beta compatibility issue, and whether a hotfix is planned?

Thank you.

I am experiencing the exact same issue, thank you for your wonderfully written explanation.

I have the exact same issue, and my VM is automatically starting, which means I cannot even open Parralels at all.

Still no feedback on this?

 

[MolaM]

Michaelv38 and I are still experiencing this issue. I would appreciate any updates, though I understand that changes to how new macOS opens programs may make this more difficult to resolve.

 

[MolaM]

I have the exact same issue, and my VM is automatically starting, which means I cannot even open Parralels at all.

Use key binds (command+options+F) while quickly first opening VM to switch it out of full screen to stop it from crashing and then just unfortunately reframe your VM. (what I had to do)

 

[Michaelv38]

Yes, I am able to use it now, but if it is in Windowed mode, I can only use 1 of my 3 screens, which is quite the hassle.

 

[Michaelv38]

I think this issue is resolved now. Not having any further crashing issues.

Hopefully this issue isresolved now. if not follow this: This appears to be a compatibility issue between Parallels Desktop 26.3.3 and macOS 27 beta, specifically when entering Full Screen mode. Until a fix is released, keep the VM Startup View set to Window mode to avoid the crash. The Parallels team should review the crash logs and confirm whether a hotfix or update for macOS 27 beta compatibility is planned.
