    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.
