SOCD report detected: (AP watchdog expired)

@mikeswat: sorry to hear about your problem. I'm grateful that you posted here so quick. I'm in a similar business, with 3 M1 Macs. Now I know and I will not upgrade to 11.5.2 I'll stick with 11.5.1 until they fix this mess. Hope you can find a fix or workaround.

sorry mean't to link this diagram instead from https://support.apple.com/en-ca/guide/security/sec59b0b31ff/web

other possible meaning for D in SOCD

-direct memory access (DMA)

-DRAM

i can't see any use further troubleshooting this. it's a black box that can only be fixed by vendor.

my guess is it's a real doozy of a bug too.

Mac mini (M1, 2020) I have this problem too. After over 10 years trouble free out of my first mac, the problem is a real disappointment. I have a western hard drive , but it makes no difference whether it is in or out.

After the previous updates I think it happened once. When I first had the mac it was more frequent but one of the updates kept it at bay for a long time.

I am certain it is a graphics card issue. My screen over the past 2 weeks (after the latest update 11.52 20G95) the screen has gone blank 3 times. I had to restart once & it was ok for a while, but it was more frequent over the past couple of days, so I restarted yesterday & today green screen of death and an auto reboot, I was right in the middle of something as well. Now I have to plug the hard disk into my Ubuntu laptop because when the machine crashes, I get an error & the disk won't connect. What a joke.

If they want me to start installing & messing around, I'll be sending an invoice. Paid top dollar for this and Apple are all out of goodwill at the present time with me.

Can't remember the options, but I did use the migration assistant. It worked really well - no issues. I was careful didn't transfer any 'programs'. Only installing those that were compatible with M1.

Fresh out the box and multiple issues, that is not good at ll. That is just like what I have going on. I got a refurbished unit, normally have pretty good luck them but this is just sad, had high hopes for this unit, guess I’ll have to wait until the new stuff comes out to see if it fares better.

The performance seems pretty good for the air, the MacBook Pro, Mini and iMac should have probably gotten the M1X (or whatever, it will be called) chip. Something with better performance allowing more ports. I was thinking maybe I’ll get an Air instead, since my wife’s unit works great.

I'm a MacBook Air (M1) user and I have had the SOCD issue, which I have previously posted about, as have other MacBook Air users. Have only had it occur once though.

Does seem predominantly the mini, but Air users are not immune.

I got the Air now and it is working fine, no issues with the drive yet but I have it formatted as ExFat to move files from my PC. Tested with the USB C to DisplayPort cable into the LG monitor and it works fine. I'll install some software and test the video editing on it, using the external to see how it fares and report back.

Apple must to find a fix for that. This is a very bad situation for the professional Photographers ... its so difficult not using 2 drives at least , for the double backup ... This is annoying .... Same issue here 2 times , one a week "green screen

My MacBook Air has been pretty solid since I got it. I have it plugged into an OWC hub, with a USB C to DisplayPort cable to my LG 32" monitor, along with an ACASIS external TB/USB 4 drive, with a WD SN750 drive installed. It's not quite a month yet and I can recall about 2 times when it crashed while using it and probably 3 times that I left it asleep and came back and found it had crashed. To be honest, I use my wife's laptop more as it is more accessible, mine is connected to the hub and used as a "desktop". This setup is my replacement for the Mac Mini I wanted to use as a desktop replacement for my old 2009 Mac Pro, until the Pro laptops come out.

Has anyone installed this update that came out yesterday (well, that's when I noticed it)?

Device Support Update

This update ensures proper updating and restoring for iOS and iPadOS devices with a Mac.

There wasn't much info on what it does but wanted to see if that does anything to resolve this issue. The last crash I got, I forgot to take note of what the cause was. Let me know if this update aids with this issue.

Mine was having the issue right out of the box. I bought the Mac Mini from the refurbished store, it would crash during the setup, which I got through by using a portable USB C/Thunderbolt monitor. It was the most frustrating few days. When I took it in to the store to return, one of the folks wanted me to setup an appointment to speak with someone at the Genius Bar. I replied, I spent many days messing with it and don't want to fix it, since it came out of the box like that, I wanted a refund. He processed it and later I ordered the MacBook Air. It has been working great and I am happy with it.

Let's hope they find a fix for the issue for all those suffering from it.

I have exactly the same problem. I've had my M1 Mac mini for a few months and it will panic and restart every three to five days, or thereabouts. I tried disabling 3rd party kexts (Avast and DriveDX) but that didn't help. More recently I've removed my USB C 4-port hub but, as my current uptime is only 4 hours, it's too early to tell if this will make a difference. I still have an 8TB drive plugged into one of the USB ports, and a hub plugged into the other, in addition to two LG monitors (one running through the USB C port, the other through HDMI).

I do not have this issue and I have 1 TB3 drive attached and an SSD (NVME) attached and a Blu-Ray DVD drive attached at all times. The 1 TB drive is connected through a Hub and the SSD is connected to USB-C port on my 5K monitor.

iMac 24-inch,M1, 2021, 16GB/1TB

We took delivery in mid-July, and today we experienced our first "SOCD...AP watchdog expired" episode with an involuntary restart. I have a 320 GB Seagate HDD connected via an adapter for Time Machine backup. Aside from an issue with the display resolution zooming in and out by itself yesterday, we have had no problems at all. I will continue to monitor and will update if this glitch continues to occur.

Just happened to me - November 2021 after purchasing and using M1 Mini since February.

Green screen of death?

I do have an external HD connected...but have had it that way for months.

Feels like a memory issue...and I hadn't restarted in a long time. Many, many browser windows, Excel, Word, Teams etc. etc.
