Panic - Watchdog Timeout: no checkins from watchdogd in 185 seconds

Were you by any chance also running Time Machine backup?

Someone at work thinks Time Machine maybe a common trigger for some users. I'm just trying to gather any supporting evidence, or refute the claim so time is not wasted looking explicitly at Time Machine, but maybe on the conditions running Time Machine creates, and then see if there are other apps that create similar conditions.

Someone else found the panics went away after removing a USB dongle for wireless mouse, so it is also possible that Time Machine was talking to a USB disk, and it is the USB device that is the common item.

Anyway, I would be interested in what information you can pass along.

How wonderful of them....Based on your feedback to others I've deleted Webroot security. So far ok, no freezing since I posted the original question about Big Sur. I'll post back in a couple of days with an update in case others are interested.

Bob, I came across this thread in search of a solution to this problem, which started to occur on my iMac 2017 since I installed the MacOS 10.15.6 update about 24 hours before. I didn't have the problem previously, but now it occured twice within 24 hours.

I also have a permanently connected external UBS drive that I use for TimeMachine backups. I had issues with that external drive when I upgraded to Catalina a few weeks ago as I had to disable sleep mode for hard disks to avoid the drive being constantly dismounted.

Not sure that helps in regard of "sharpening" your theory.

That is good to know, thanks, but not really surprising as no third party security apps have any role to play on any Mac, particularly after Catalina brought in more security.

Deadly embraces between two security systems can cause kernel panics.

I had this happen today twice on two different machines connected to the same network: Macbook Pro (15", 2017) WiFi only and Mac Pro (2019) wire only. Both are running 10.15.6. Macbook Pro came back from sleep (I don't remember when I last rebooted it), but MacPro was only running for maybe 30 minutes and never went to sleep. I both situations I was using a Chrome browser. Macbook pro was the first "victim" and I though that Chrome ran out of the swap space (I though my SSD was tight). However after crash I checked and I still have about 48GB of disk left. Note that in both cases the system just froze for a minute or two before it crashed. I have "OnHub Wireless Router from Google and TP-LINK, Color Blue" with Google WiFi points. Macbook Pro had no external devices attached. Mac Pro had few disks (USB 3.0 and Thunderbolt 2).

If I were you I would create a new discussion and paste in a copy of this post.

This thread will not be visited by experienced volunteers now. It is stale.

I suspect the encrypted/Filesafe (?) formatting is working against you. Plain APFS would be the norm but I don't know why it will not let you reformat it.

Getting the same panic since updating my Mini Late 2012 to 10.15.6.

System is running on external USB3 Samsung T5 SSD.

Was ok before 10.15.6

Yes, those are a good idea - I've had power nap and HDD sleep disabled all along.

I'm going to try running  Caffeine again, in the hope it'll stop the panics happening quite so often.

Please report it, as a beta tester, your reports will get closer to developers than anything in these forums.

I have same problem with Unity.

Just install windows - and its fixed.

I believe 11.2.2 has some changes for some Macs to prevent unauthorised USB hubs causing damage. Hubs were often suspected of causing kernel panics too.

Hi Peter,

Does your solution also work for my Mac mini 2018 (3,2 GHz 6-Core Intel Core i7, 32GB RAM, 1TB SSD) version 10.15.4 (19E287)? It also has this error every time it shuts down after a running for few hours. What happens is that my user session is logged off, my screen goes black but the light on my Mac mini stays on. After about 5 minutes, it reboots itself. When I login, the shutdown goes normal. This was always the case with my Mac.

I tried resetting PRAM, SMC, Save boot (which also clears caches), a clean install of Catalina and manually copying back my files (not a restore from Time Machine). Still the same error every time I shutdown my Mac after a few hours uptime.

I called Apple support twice but they do not have any solution other than to send it in for repair. I do have Apple Care but to me, this seems an OS related issue. Not a hardware one.

Thank you in advance for your help!

Apple machines sell for a premium price with a hardware warranty of 1 year and their solution to a software problem is to tell you to take it in for repair!! I'm not sure what justifies the premium price

I’m curious. What led you to suspect that the COMBO update would fix this?

was it just a lucky random choice, or was it something in the panic itself that gave you the insight that the Update process wasn’t working?

I too have been having frequent panics on my MacBook Pro 16" 2019 so I am currently downloading the COMBO 10.15.5 to see whether that solves the problem.

I have a permanently connected USB hard drive for regular Time Machine backups. I also use an external screen.

Are there any tests that I could perform to help you, either before or after installing the COMBO update?
