M1 Mac SOCD report detected: (AP watchdog expired)

Please don't post if you have nothing substantial to contribute with.

This just happened to me - M1 MBA, disconnected from power, no peripherals or anything plugged in. I had upgraded to Ventura about two hours ago.

Anything video running when this happened, do you know? Even a screensaver?

Nope. I had Affinity Photo open with a small file in the background, and had Mail open in the front, and was just reading my inbox when the screen just turned off and the MBA rebooted.

Well, at least Affinity Photo is a pretty graphics demanding application.
You see, there are plenty of reports on this that mention it happening while running some sort of video/graphic software, so I feel that it might have to do with system-on-a-chip, graphic cores on cpu, and shared memory between cpu and gpu. And one thing's for certain; it only happens on 'SOC' apple silicon.

Yeah, it's interesting. I've been pushing this MBA with Affinity Photo for more than a year, yet the first time I've had this error was literally just hours after I'd upgraded to Ventura.

This happened to me for a second time. M1 Pro 16" MacBook Pro.

The first time was 45 days ago and it made a loud popping sound that scared the life out of me and there was graphical glitchiness on the screen, green and pink. The only thing plugged in at the time was a charger.

It happened a second time yesterday. No graphical glitch - the screen just turned black. The popping sound was a lot softer. I had nothing at all plugged into my MacBook this time - not even the charger. I don't remember what I was doing the first time it happened, but I was watching a YouTube video in Firefox this time. When it rebooted, it displayed the same error as before. I took a screenshot both times: "SOCD report detected: (AP watchdog expired)"

I also saved the diag report this time.



I still have 2 months on my 1-yr warranty. I know some people have had their logic boards replaced because of this, but I also see some of those people still had this issue afterward. I wish Apple would just come out and say they are aware of the issue and working to resolve it. I'd be fine with waiting until they push out a fix. Instead I'm contemplating whether to waste my time having them replace hardware unnecessarily, and leaving me without a computer in the process.

Just happened again for the third time. Seems to be happening monthly now. No sound or glitchiness on screen when it crashed. The screen just went black and after a few seconds the computer rebooted. I had just opened a new tab in Firefox and went to YouTube when it happened. The second the page loaded, the computer crashed on me. I had not even started a video yet. I can't help but think this has something to do with YouTube's website since I'm on their site every time it happens. But I also just spend a lot of time on YouTube, so it could be a coincidence. Like last time, nothing was plug into any port - not even the charger. Other running apps include Safari (two tabs), and iMessage - that's all. I have about a month left on my warranty. I should probably schedule an appointment with the Genius bar. I hate this.

 

[Ben J.]

Thanks for reporting.
Even though you hadn't yet clicked on and started a video, there is often a little preview video playing when you hover the pointer over them. So my hypothesis that it's something graphic/video related still stands.

I think you should. Save the error messages as screenshots or text and make them read it too. I think for some machines it's just software (it happened only once in my iMac in over a year of 10 hours a day use), for others it must be hardware. Or this problem would be more diffused if it were only software. I know some had the problem go away with a new computer from Apple

 

[Nugat Trailers]

My suspicion, and it's really only a guess, is that this is a problem related to Macs that have an 'early' M1.

I've only heard of this affecting MacBook Airs, Pros, and Minis, except for the user above who said he had it happen to his iMac once, but I haven't heard of any 14/16 inch Pros, Studios or M2s being hit, plus it still happens to users on Big Sur and Monterey. (Likely Ventura as well, but it's so early in the release that I can't be sure.)

I suspect it's a hardware issue that is caused by either a USB hub being connected, or by video streaming. Possibly both.

It's annoying, to be fair, my Mini does it every 7-9 days. Granted, I mostly avoid it by restarting it every 6.

On Apple discussions board I've heard others with iMac, and also MacBooks pro with M1 Pro and Ultra. So I don't think it's something related to the early M1s.. but yeah Mini do seem particularly affected, but maybe because they sell well and there are many units (as the Air)

 

[SlCKB0Y]

The unit has never been paired to a BT device, nor has WiFi ever been used. Both are software "Disabled", for what that's worth. The system is primarily operated with the video monitor turned off (soft-off) using ScreenSharing over Ethernet. The system is not internet connected, and no system updates have ever been applied. [virgin as-purchased]

It was logged into the App Store briefly to obtain FinalCut Pro. 3rd party apps installed are VLC video player, Handbrake, HDpvrCapture and StarryNight Pro 8. Only VLC and video capture apps have been active during an event. No "drivers" have ever been knowingly applied.

This MacMini has 16GB ram and 1TB internal storage. (The 2TB version was "special order" and this was in stock) The System OS is 11.3.1 Big Sur, as shipped.

I am still running the original *as shipped* M1 MacMini macOS 11.3.1 (Build 20E241) with no updates whatsoever. I declined the firmware update when first setting up the unit and did not permit any "updates" to OS or Apps. The only permitted activity was accessing the App Store to obtain FinalCut Pro. Other app loads were performed offline "sneaker-net" style.

This M1 has had no internet connectivity since that occasion (last year).

Well this all seems like a pretty weird usage pattern. Why would you do all of this?

 

[___joshuaturner]

This has just recently started happening to my M1 Pro from last year. No USB/Thunderbolt accessories were plugged in. All restarts have been when the computer goes to sleep. As soon as it enters sleep mode, it panics and restarts.

A little annoyed, but it looks like I'm going to the Apple Store next week.

And this just started happening? Any recent new software installed, or major settings changed?
Do you get the 'watchdog expired' message?

You know, you could just turn sleep off. Many, if not most of us do these days. There is no real need to shut down or restart other than for specific occasions like doing updates that requires it.

This just happened to my iMac M1. Just out of warranty - of course. No apple care - didn't think I'd need it on a desktop. Ha! Hope it doesn't happen again but doesn't sound too promising. Had a multitude of tabs open, moved my finger on the trackpad and poof, reboot.

 

[darksavior]

Finally got this SOCD error for the first time. Watching a video on chrome. Green screen then auto rebooted. After the reboot, it wouldn't give me internet access on ethernet. I had to turn it off/on again for it to give me a valid ip address again.

Mac mini M1 16GB. Ventura 13.1. Using hdmi on a sony x80j 4k60 tv when it happened. I have usb peripherals connected but I've been using some for around 2yrs (14tb wd, asus nvme enclosure with samsung nvme, monoprice usb-c to dp adapter, monoprice usb hub). Others a few months (anker 7 in 1 usb hub, hyper-x usb headphones). I put my mac to sleep at night but I must've done a manual reboot maybe a few weeks ago.

Overall, Ventura has been the most stable. Big Sur was a buggy mess with the most crash reboots and the Monterey betas crippled my usb-c to DP adapter. I've only done os upgrades. If it happens again I'll consider a clean install.

 

[iancottam]

Anyone tried the beta of 13.3 yet to see if they have fixed the SOCD problem?

 

[coso]

Just to report, I never had the error again on my 18 months old M1 iMac

For watching videos I have the Vinegar/Baking Soda plugins though, don't know if that matters

 

[dono42]

Had first SOCD report detected: (AP watchdog expired)
M1 Mini (apple refurbed) 8G x 256G installed 01/27/23, Monterey 12.6.3 (21G419) runs 24/7
Main application SecuritySpy, Lacie Raid Manager via Rosetta, minor Printopia (lots of graphic processing)
Thunderbolt3 -> Thunderbolt 2 adapter -> Lacie 5Big
Thunderbolt3 -> OWC Envoy Express
HDMI -> Dell 2408wfp
USB -> Dell hub -> Keyboard and mouse
USB -> Anker Ethernet -> POE switch -> cameras
Basically no user interaction other than me checking logs.
I did not report to apple, will if it happens again.

 

[EncryptedUser]

I suddenly began experiencing these reboots after I attached my two USB-C raid chassies from OWC.
I migrated them from a Mac mini 2012 which I used as a server and when I had them connected to my 2020 M1 Mac mini one of them often lost connection with the mini.
Same USB-C to USB 3 cables as I've used for years with my Intel mini.
Also a couple of SOCD reboots occurred.
Made sure they were firmly attached, tried via a USB-C hub to 2xUSB 3 + 2xUCB-C but still crashes and reboots.

I then bought new cables 50cm USB-C PD 60W capable cables and suddenly everything was rock solid via the same USB-C hub.
No disconnects. No crashes. No reboots.

 

[dono42]

Had second failure today, reported to apple, disconnected TB3 device.

 

[Ben J.]

A little over three months with my M2 Mac Mini, and yet to have a 'SOCD Watchdog' error. Exact same setup/devices/usage as my M1 Mini, except Ventura instead of Big Sur, which had them regularly.

Fingers crossed.
(I guess I've jinxed myself now.)

Exactly my issue! I have nightly crashes, all and always while in sleep. My MBP was already reinstalled, it has been serviced by apple, yet the issue persists. Aggravating and unacceptable for such an expensive piece of hardware.

Happened to my M1 Mac mini for the first time today while I was at work.
Nothing running. Not backing up since that happens at 2am.
Monterrey 12.5.1.

Six months now since going M1 to M2, and Big Sur to Ventura.
NO AP Watchdog SOCD error!

So in my view, it's most likely the processor or the OS - or a combination of the two, that causes the error.

 

[KernelG]

I'm still on an M1 Mac mini and just upgraded to Ventura. A few devs were very late on compatibility this time around (I suspect security changes are making certain copy protection schemes more difficult). I've been pushing the machine since, watching lots of YouTube videos, not rebooting after 3 days, etc., and have had zero AP Watchdog SOCD errors. So this may have been fix-able via the OS, whatever the issue actually was.

I'll be buying a new M2 Mac Studio in a couple of weeks. If I do see any errors on the mini in the mean time, I'll have a control going forward, all other things being equal.
