I have been reporting through Feedback Assistant almost daily our Mac Studio's panic at Shutdown since 14.1 betas started. If the Mac is shut down at the login screen or immediately after logging in, it will execute a normal shutdown. If used for any length of time beyond that, it will panic at shutdown and reboot.

After several weeks, it appears this panic is related to ChronoSync. On days when the MacStudio runs a Chronosync scheduled tasks, it will panic at shutdown. I blocked all scheduled CS tasks for two weeks, and the system never panicked. I've run two CS sync tasks manually, and each time, the MacStudio panicked at shutdown. I have reached out to the developer.

UPDATE: This issue persists in the current 14.1 RC. I do use Feedback Assistant and share sysdiagnose info with Apple. The affected system is a 2022 Mac Studio M1 Ultra 128GB, 4 TB SSD. The installation of macOS 14 is clean, not an upgrade. When macOS 14 was released, the Mac was erased, and the official release version of macOS 14 was installed. All software was reloaded, not restored from a Time Machine or other backup.

This issue continues in the 14.2 beta 3 release as well.

If this Mac Studio is used for more than a few minutes, it will panic when it is shut down and immediately reboot. This has continued since 14.1. I've done a clean install of the OS and reinstalled all apps from downloads from other developer's sites.
