Hi everybody,

So I bought my M1 Macbook Air (16GB) three months ago. Since then the MacBook has been working more or less flawlessly with the exception of a freeze and restart and the error "SOCD report detected: (AP watchdog expired)" a couple of days ago. After that day it did not happen again.


First of all: I am usually using my MacBook with an external monitor (Razer Raptor 27) which is connected via HDMI over the official Apple USB‑C Digital AV Multiport Adapter. The USB-A Port is connected to an Audio Interface (Native Instruments Komplete Audio 2) and I charge the MacBook via the USB-C charging port of the adapter. OS is always up to date. Didn't have any problems with the adapter for the period I used it (bought it with the MacBook).

That day I was just casually watching a movie on Amazon Prime in a Watch Party and after having watched that movie and quitting Google Chrome, I realized I forgot to quit Adobe XD and Adobe Photoshop in which I did some work prior to watching the movie. After quitting XD my Macbook Air froze, the screen got pinkish and it restarted and gave me the error: SOCD report detected: (AP watchdog expired). I did send an error report to Apple via the button of the error message popup. I also did use an external WD My Passport 1TB SSD (APFS format) which I didn't eject "properly" (just pulled the USB C plug after moving data).

I researched about the mentioned error and found all kinds of reasons why people got that error message: WD Hard drives, motherboard failures, faulty CPUs, software issues, external USB-C and USB-A accessories etc.

I then talked to the Apple support and even after talking to the senior techsupport department they couldn't find a solution of why the error happened. They advised me to continue using my MacBook and look out for a reproduction of the error.

I also just recently did a stress test to check if my CPU might be a problem, but the MacBook didn't crash during it. I also did a Hardware check via the Apple Diagnostics feature. This also didn't contain any error codes.

Today I made a report via EtreCheck Pro. I attached some Screenshots.

Did anybody else of you have the same issue? I really want to make sure that this is not a hardware related issue. The MacBook was very expensive and I expect a flawlessly working machine...

Thanks in advance!

Are you getting consistent kernel panics, or just a single one? I couldn't tell given how your post was written - its early and I've not had my full allotment of coffee?

If its a single one, then chalk it up to one of those things and just be mindful. If you're getting them semi-regularly, then start disconnecting any and all external devices and keep using it, to determine if its better or not.

Kps can be a sign of a hardware issue, but a single one may just be an outlier with no indications that its a hardware failure

This is a well known problem.
Discussed here:
M1 Mac SOCD report detected: (AP watchdog expired)

No one really seems to know anything, and Apple is pretending it doesn't exist.

This is what I know from my own experience and from reading peoples' reports:
Almost certainly, this is an Apple silicon issue. No reports from intel-based mac users.
It happens to people with all kinds of configurations and connections, and with people with a laptop mac with absolutely nothing connected, so it's not because you have this or that connected, or anything.
Sometimes it causes some graphic/audio weirdness (like the pink dots) for a second before the automatic restart, sometimes not.
It does not cause any kind of permanent damage.

Over the last year since I got my M1 Mini, I've had perhaps 5 of these. So it's not a big problem, at least for me, but annoying - and it can look a bit scary, and cause concern. But I say, it's not broke anything for me, except if I hadn't hit 'save' for a while.

My hunch is that since many people mention watching video when it happens, it might be simply a very low-level design flaw with the SoC (system on a chip) with CPUs and GPUs sharing memory and whatnot.

What is "AP Watchdog", anyway? Any one know?

Until now it only happened once (the one occasion I described in the thread). Thanks for the reply!

Hi Ben, thanks for the reply! So far it only happened once to me and I just hope it will be the last one. I'm pretty OCD when it comes to my devices. On the other hand, MacBooks are god damn expensive and I think we all can expect to have flawless machines considering their prices...

For my M1 Mac Studio and M1 iMac here I have only seen KP's for two issues:
1. Outdated drivers for NTFS and ExtFS
And
2. While playing video in the browser, both Safari and Chrome.

#1 was fixed shortly after Ventura came out, #2 happens quite rarely, but it always happened while the browser is playing streaming video.

Another confirmation of my hunch that running some kind of video is a factor, then. Thanks.

Doubtful watching videos is the root cause since I haven't experienced it once in two years watching videos with Chrome. Looking at other symptoms of this like audio crackling it seems like a power delivery issue so possibly similar to case with bad/insufficient capacitor on 2010 MBP causing kernel panics (see link below). That's why people with persistent issues without anything connected and clean install of MacOS have only been able to fix with logic board replacement.

"If you have a 2010 15" Macbook Pro with an 820-2850 board with random kernel panics, this will often fix your problem. You will have to scrape away the ground plane with tweezers or a fiberglass pen in order to make this fit. This will NOT always fix the problem, but does a good amount of the time. There is no guarantee that this will repair your problem and no warranty expressed or implied if you destroy your machine."

The thing is: a lot of people seem to encounter the kernel panic in combination with the above mentioned error code once or twice not more. I mean if my Mac would crash frequently (i. e. once every 2 weeks or so) then it would be an obvious Hardware failure in my eyes. So far it didn’t crash again…

To add a data point to this thread:

Just had my first SOCD report detected: (AP watchdog expired) episode today.
I've got a 2021 M1 iMac running Monterey 12.6.3. The only external connection (other than 120VAC power plug) was an iPhone charging via USB. I was browsing on Chrome and NO VIDEO streaming.
My iMac is 5 months out of warranty so this is pretty upsetting. I ran Disk Utility with no errors reported.

I'm hoping this is a "one and done" situation but knowing my luck .....

Welcome to the club. :(:(
I just want to say that I think that, depending a bit on how you use the computer, you should be prepared that it might happen again, BUT:
I've yet to hear reports of anything breaking with these crashes. These types of 'hard crash' kernel panic can seem scary but nothing breaks. You might loose unsaved work, but that's it, and with the speed of these macs, it's up and running again within a minute or less.

I've had my mac mini for about a year now. I keep it running all the time, I use it for music work, photo editing, video, every day, and I use it for TV and video streaming in the evenings. I have lots stuff connected; monitors, ssds, ethernet controllers, docks, usb and bluetooth devices - it's practically maxed out utilization-wise.

I'm guessing I've had about six of these 'watchdog panics', that's about one every two months. I can live with that. It's a fantastic machine.

But let's hope yours is a one-time event. ;)

Thanks for the feedback Ben. I'm not running anything "mission critical" on my mac so I don't mind the occasional crash. I just don't want to fork over a large $um of money to Apple for a new motherboard, power supply or other expensive hardware + labor.

I just had this happened to me yesterday for the first time.

Macbook Air (M1, 2020) running Monterey 12.6.3.

Was on battery mode (about 18% of power left) and watching a YouTube video when this happened.

There was no external HDD connected. The only thing connected was an external mouse.

Never happened before 12.6.3.

12.3.1 was the best Monterey version for me. Super stable and never gave me an issue.

Makes me regret updating to 12.6.3.

Waiting for Ventura to mature before upgrading.

I hope this is a one time thing or I'll be jumping back to Windows/Linux.



Off topic:

When I was running 12.3.1 not too long ago, I checked my battery health (out of curiosity) and it said 100%.

After updating to 12.6.3, I checked again. Now, it's 94%.

Coincidence? Maybe. But Apple's known to be notorious in weakening batteries after doing an OS update.

Also happened to my iPad after updating to the latest iOS. The battery drains much faster. I'm quite observant on my devices so I know when something isn't right.

Sucks that Apple is still doing this.

Update - No idea if this is connected with prior SOCD incident but I'm now locked out of my Mac. I don't have a startup password and just leave that field empty when booting up. Now I can't get past that screen. Tired booting in Recovery mode and disk utility shows my 1 tb SSD has 895GB available and PREBOOT zero KB available. When I select REINSTALL MONTEREY, and Macintosh HD it says "This volume cannot be downgraded:.
I'm stuck!

AP Watchdog is a daemon that writes analytic bug reports, its not active in these situations because the crash was so severe it was a instant reboot not a shutdown. This happened today to me on a phone 12pro, it appears to be fairly common on this device as well, in the last week there has been a huge rise is reports of this error on the iphone 12 pro, the reason for that is open to interpretation, my guess is this is a software glitch, its far to coincidental that 12 pros would all start glitching again in the same week.

SOCD report detected: (AP watchdog expired)

Have this issue every time I close my MacBook Pro M1 2020 and something is connected to the USB-C closest to the corner, be it the charger or any other thing. This ****ed up one of my external discs. It should definitely be flawless man. Warranty expired as well. I now have to be always careful of not closing it when something is connected to this first usbc. And it has only twooooo!!! mf
No other issues in the meantime though. And it happened more than 20 times already.
