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.

I spent a long time with Apple support looking at dumps from the panics on my machine - they found nothing useful.


However, their advice worked. I installed a completely new system on an external drive, and recreated the users - not copying them from previous backups. I've only copied over applications as I've needed them specifically.


I've now not had any panics for over two months. They were occurring twice a day. So, I don't know what third party was causing the problem, but that was what was the ætiology.

On my Mac Pro, it was being caused by the McAfee kext mandated by my employer. Started in safe mode, rock solid for three weeks. Started with McAfee, crash within a few hours. Has been up continuously since I was allowed to get rid of McAFee going on three weeks now with pretty close to 100% CPU utilization during that time. Just FYI.

If you have McAfee 10.6.6, you can put it into kext-less mode, which has helped at my employer (same mandate for company Macs)

This is a frustrating issue. I have a late 2013 27" iMac with one external monitor and 3 external drives, and this happens almost daily when I attempt a shutdown. I regularly run CleanMyMac and Disc Utility to make sure everything is clean and in proper order. Zero response from Apple when submitting this problem. I've run all the updates and am current and this still continues. Frustrating it is not being worked on.

I just started getting these "panics" after upgrading to Catalina on my 2014 Mac Mini. I'm running Webroot, but it never "caused" any problems before, and it caught something once, some sort of threat, so I keep it. I installed the 10.15.6 Combo Update but I still get these.


They occur intermittently when I attempt to shut down, and it restarts instead saying there was this problem. Or an application will become unresponsive, and when I restart, I'll get it.


Including my latest report below, but I don't understand how to read it. Firefox had become unresponsive, so I force-quit, restarted, and got this.


Any thoughts?

David

I had lots of these kernel panic error in my iMac 21.5 inch 2017 running Catalina 10.15.7. So. So, I started a very long process: disconnect every peripheral; low level format of the internal disk; fresh OS (+update) and relevant apps installation from network; restore of only documents and data form TimeMachine backup; peripherals connected; all, with frequent shutdowns to check for the problem arising again. It didn´t show up.

Then, I got an error and decided to format the TimeMachine disk just in case. After a fresh full backup, the error showed up again; this time I noticed that the TimeMachine disk was "growling" a lot after the shutdown command and I got the restart and the kernel panic error.

My easy fix: I just eject the TimeMachine disk before shutdown, and everything goes well. I also have an external monitor that doen´t seem to matter to my process.

Hope it helps someone until Apple finds a way out.

I had a warning from ESET AntiVirus instalation some time ago that I had ClamXav installed, and I did not know about such program and could not find it. But I was inspired by peter_watt and did one more special search. I found a folder inside /usr/local/ named ClamXav and deleted it. Someone knows anything about a relation between ClamXav and kernel panics?

Wonder if you all can help with this. Similar problem but I can run off an external HDD boot drive:


2014 iMac 32GB Catalina 10.15.7 1TB internal SSD encrypted with built-in FileSafe.


If I could just restore to my internal SSD...


  • Started getting panic -watchdog timeouts yesterday for the first time
  • They occur usually around 97 seconds after logging in, sometimes longer
  • I cannot log on in safe mode. The machine takes forever and goes back to the login screen
  • I disabled all energy savers
  • I tried booting into recovery mode to reinstall MacOS (10.15.7). I do not see my internal SSD. I get "examining volumes" forever until the machine goes to a black screen
  • To reinstall MacOS since recovery mode failed, I tried creating an external flash drive with the installcatalina app as instructed in another Apple Support page. When I boot up with option key down, I see that flash drive but it won't find my internal SSD ("examining volumes" never stops)
  • I have a Time Machine backup. I can't restore it to my hard drive. When I boot off my internal SSD, the machine crashes before I can do anything.
  • I restored my time machine backup (from before crashes started) to an external HDD and booted off that — which is how I am online now. It's horribly slow but it works. No crashes. I don't get kernel panics booting up in this external HDD.
  • When booted up off my external HDD, I get an error message that my internal SSD is locked and can't be opened. I don't even see it in Disk Utility.


My latest Crash Report below. This is maddening. I saw the AppleSMC line below and did do an SMC reset.

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.
