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

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.
