SOCD report detected: (AP watchdog expired)

Mac Mini M1 16GB keeps crashing and then restarting randomly on all applications with following error message:

I was asked by Apple second level support to provide details of the crash reports logged when it happens. 

It is [SOCD report detected: (AP watchdog expired)


SOCD report detected: (AP watchdog expired)


Even when idle. 


Steps taken with 2nd level support:

  1. MAC OS REINSTALL.
  2. MAC DISK ERASE AND REINSTALL FROM ICLOUD.
  3. ISSUE ALSO HAPPENS IN GUEST MODE LOG IN.


Mac mini, macOS 11.2

Apple 2nd level support seemed to think it was due to external hard drive issues. They asked me to test without drive connected.


can confirm now that the SOCD crash would only occur with My external USB A Western Digital Hard drive physically connected. After disconnecting it has not happened again, so far. After 5 days.


do you all have external drives connected?

Just happened to me for the first time. Green screen followed by restart and SOCD report detected: (AP watchdog expired) message. I'm a video editor, running Mac Mini M1 (2020), working in Premiere Pro 2022 and I have a WD 4TB drive plugged in, which is consistent with other users. Any solutions to avoid this happening again greatly appreciated.

Finally getting so fed up, had to join in the chorus here. Macbook 14, received mid-December 2021, crashes in all situations since receiving it. At least 3 different tickets to Apple support, gathered crash data and uploaded numerous times, no word from Apples 'engineers' that are above the level of phone support.


How hard is it to request a replacement laptop? Makes me want to swear.

2020 M1, been happening more and more frequently. The last time the glitchy noise made during the crash blew the left speaker, which now sounds tinny at higher than half volume. I assume I'll be ignored at an Apple store since it's past the 1-year warranty? Pretty crazy to have no recourse for a +$1000 laptop with a clear hardware defect that's damaging other hardware.
