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

Most of the time I reboot my MBP 15-inch Mid 2014 with macOS Catalina 10.15.3 I get this... I tried PRAM and SCM reset but it comes back.

Backup.

Go to https://support.apple.com/downloads/macos and look for 10.15.4 COMBO update.

Download and run it.


Also some types of External monitors still cause kernel panics.

Thanks to @dragontorc, he clued me in that "there are numerous reports from many users for kernel panics caused by a memory leak associated with a bug on the App Sandbox. VMWare and VirtualBox had already identified the issue."

and

"Apparently Apple is aware of the bug and I suppose a supplemental update containing a fix is currently in the works."


In my case I use VMWare Fusion...

I have the same issue but it STARTED with 10.15.6.


2013 Mac Pro, kernel panic every night since 10.15.6. also happens during the day if the Mac Pro is idle long enough. I've reinstalled macOS from recovery, no luck.


Oddly, it also kills Messages, forcing me to log back in. Once it was unsuccessful, which is when I reinstalled macOS. That fixed Messages, but not the kernel panics.

I too have been experiencing these CPU Panic's since the 10.15.6 update.

I have a MBP 2018, connected via USB C to a Dell Monitor, and a Graphics Accellerator.

Since the 10.15.6 update the USB-C behaviour has been very patchy and I often have to pull the cable to my monitor and re-attach it to get the MBP to wake up.

I can see the mouse moving on both screens but it does not allow me to log in, and I have to hard shutdown the MBP.

And for a week or more, overnight now, I get the same CPU panic that brought me to this thread.

Any solutions to this ?

I have the same problem, but it is infrequent. I have an "always on" iMac running 10.15.6 (Retina 5K, 27-inch, 2019, 3.6 GHz 8-Core Intel Core i9).


It seems to shutdown sometime overnight when it is in a rather quiescent state.


This iMac spontaneously shuts down every ~48 hours.


I can't correlate this directly to upgrading to 10.15.6, but it is definitely running 10.15.6.


Prior to this episode, this iMac would run without shutting down or rebooting for ~20-40 days at a time.


So far, it has not shutdown while I was actively using it.

Same issue on both of my Macbook Pro 16"s.... Start happening about a week ago, so probably in-line with a recent update.


Macbook crashes every time it goes to sleep. Using caffeinate, or a wrapper around it (such as Keeping You Awake), keeps the issue at bay as it stops sleeping. I use an external monitor which might relate.


Please test your updates at Apple before sending them out to everyone. I shouldn't have to hard reboot every time a $2000 laptop goes to sleep.

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).

Same issue as posted by everyone here.


panic(cpu 2 caller 0xffffff7f9e3c7ad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds


2013 Mac Pro running Catalina 10.15.6 with two Apple Thunderbolt displays, TimeMachine to external SSD, Avira Security software. Bluetooth keyboard, Anker wireless mouse with USB dongle.


Crashes happen at least daily, sometimes more often, no clear pattern to circumstances.


Have just installed the recommended 10.15.4 COMBO - will see if it makes any difference.

As a follow up, this was fixed for me with the August 12 10.15.6 supplemental update, as mentioned here https://www.macrumors.com/2020/08/12/apple-releases-macos-10-16-5-supplemental-update/. Note that this update is different from just '10.15.6'... it seems Apple doesn't like to increment minor numbers and is still calling this 10.15.6 supplement update.
