<< Solved >> Help with "Your computer was restarted because of a problem." Ventura 13.2.1

[BusterMachine]

This started to happen just yesterday. The only new things that i have done to my hack recently is, install a new WD Black NVMe and cloned the OS from a Samsung also I update to 13.2.1. Also updated to OC 089

Since I was away from my desk when this happens, and with all the searching online the only thing I can think of is what some describe as a bug when the screen saver kicks in (I have disabled it to see if that is a cure). Unusual as I have never had this issue in all the years. Below is the report if anyone can help?

When updating to OC 0.8.9 did you enable the Misc > Debug > DisableWatchDog entry?

As the panic above is related to the watchdogd from com.apple.driver.watchdog.

Edhawk, I just checked and it is set to False. I have never changed it before (it is in the release sample config file), dose it need to be True?

So far the issue has not happen when I am using the computer. Only happened when I was away. I am looking at what recent changes I have personally done...

Feb 11th: installed new NVMe and cloned Ventura from previous drive.

Feb 13th: Updated to Ventura 13.2.1

Feb 14th: Updated to OC 089

Feb 23rd: Issue started

I booted in recovery and used disk utility first aid and all disks check out OK. I can't think of anything else at the moment. I have to see if happens again.

 

[Edhawk]

The OC guide tells you to set the DisableWatchDog entry to True/Enabled.

Seeing as the last change you made was updating OC I would try setting DisableWatchDog to True and see if that fixes the issue.

 

[BusterMachine]

Yes I can try that.

Currently no problems and I have turned and tested the screen saver which comes on without issue.

It is also possible there was a power interruption (for like a split second) in our area due to weather, however it did not effect anything else in the house including PC in different room.

Thanks but it is not a sleep issue. I always set sleep to never (though I do know it works on my hack).

I have changed OC watchdog setting this morning. I will mark this thread solved for now.
