Constant Kernel Panics – userspace watchdog timeout: no successful checkins from com.apple.WindowServer

Hey everyone. I had the same issue, it seems like (for me anyway) it was due to the Google Drive desktop extension. I uninstalled it and all seems to be fine since.

Hope it helps.

Wonder if it’s the same root cause as the other user reporting uninstalling Dropbox would fix it. Reducing system wake will reduce the chance of it panicking.

Do you by chance have anti-virus software installed? Had a similar issue before on Mojave, wonder if it transferred over to Catalina...

Having the same exact freezing and restart for three days now (16" MacBook Pro), after four months without any problems at all.

I'm still on 10.15.3 (19D76).

Turned off Dropbox this morning – problem gone. No problems with external monitors here. Turned on Dropbox half an hour ago. Issue happened again after 20 minutes of running Dropbox.

Interesting. I was able to reproduce it on a clean install of Catalina with no third party software installed, but I had wondered if some common third party software like Dropbox was to blame (or partly to blame).

Hey all- I'm on a 21.5" late 2015 iMac and also receiving the watchdog timeouts. It's only happened since updating to Catalina 10.15.4 (maybe right before the update too on 10.15.3?). It only happens randomly when playing The Sims 4, I notice a bad lag then my computer restarts with the error. I also received the same error after trying to have a virtual doctor appt today through Microsoft Teams (on chrome, did not download app). Didn't notice a lag but just restarted a bit after loading. Same watchdog error. I just saw some people disabling the Enable Power Nap, so I just did that and I will update on progress!
 
Hi,

I'm on a MacBook Pro (16-inch, 2019) with Catalina 10.15.4 (19E287). I was getting kernel panics for another reason (https://apple.stackexchange.com/que...e-of-high-kernel-task-cpu-usage/363933#363933) and now I am getting these ones. I may have been getting this before and haven't noticed, thinking they were the other ones.

I've had it even with everything unplugged and laptop asleep when waking it up.

Power Nap disabled, all Accessibility flags disabled too. I've had this connected to the usb-c power cord and also by itself.
 
Just had my first panic in about 2 weeks in awake from lid closed all night. I have set "Prevent computer for sleeping when display is off", and "put hard disks to sleep" is NOT turned on. Power Nap enabled. This is a bummer, thought this was fixed.
 
Just another one here. Completely frozen spinning beach ball (wasn't spinning!) today about 15 minutes into using it and I was just browsing a web page. Seems to happen more at the beginning of a restart or beginning of a day. Yesterday it took me over an hour, maybe two, of futzing with it to get it to work at all.

Running 10.15.4 and it's been MUCH WORSE since I updated from 10.15.3. 2013 MBP (Retina 15)

>panic(cpu 6 caller 0xffffff7f8fbbaa8d): watchdog timeout: no checkins from watchdogd in 93 seconds (8606 total checkins since monitoring last enabled)
Backtrace (CPU 6), Frame : Return Address

I have turned off my DropBox and Google Drive extensions/apps to see if that helps. I tried the NYC video and nothing happened -- maybe I should run it longer?
 
It's not caused by an App. The Navi graphics drivers and AppleGVA are the issue. Put you machine to sleep, open Safari, play some YouTube video to trigger AppleGVA. Repeating that cycle 20 times should give you a freeze followed by a kernel panic at least once.

I can perfectly reproduce this on my Hackintosh. With Radeon VII it runs perfectly stable for weeks without rebooting. As soon as I use my RX 5700 XT those freezes and kernel panics start to appear randomly after sleep when AppleGVA is fired up. Panic report is identical to the MBP16 reports. This issue has been around since late 2019 when Navi support was initially introduced. Until 10.15.3 the issue appeared with every sleep wake cycle. After 10.15.3 it started to only happen randomly.

I've been experiencing this on a daily basis lately. It seems like it got a lot worse with the 15.4 update, but that could be coincidental. I have a 2019 13" MBP.

Also randomly getting this panic. I am using a TS3+ dock with 2 4k monitors. I am thinking this has something to do with it in my case but it is EXTREMELY annoying.

I'm running a T3 with 2 2k monitors - I seem to have the issue somewhat less when I take the T3 out of the loop but I had to buy another display port adapter to make up for the loss of the T3...

i had the same issue. leave power nap off
 
I started getting these Panics after an update (can't recall which one) Once they started they just continued. Been happening for about 3-4 weeks.
Updated to Catalina 2 days ago and though it may have fixed the problem, buit ...NOPE! just happened again.
It's even more frustratiing now being that I am working from home and always on a VPN connection.
$6K iMac Pro turned to **** within 2 years
 
I have a Mac Pro 6,1 and have been having this issue since upgrading to Catalina. Based on these forums, it sounds like it's related to having an external display connected (which is challenging for a Mac with no internal display). I found a post in this forum https://discussions.apple.com/thread/250715149?page=20 that says to go to System Preferences > Notifications and turn ON the setting for Turn On Do Not Disturb When the screen is locked (the 3rd checkbox down). I did this and have not had a crash in several days.

I'm using a 2019 13" MBP 16gb ram , 256gb and catalina 10.15.4. I'm getting constant panics every 2 minutes, to the point I can't even use the laptop.
The laptop crashes in safe mode , as well as in recovery mode , and the hardware diagnostics give an all clear. Weird.
My touchbar has stopped working and wont turn on .

Try doing a SMC reset and see if that helps.
 
This is beyond ridiculous!

“Your computer was restarted because of a problem.”

Is Apple simply discarding those crash reports and put itself/herself/himself in sleep mode? Is that possible?

Or could it be that the problem is so severe that its developers don’t know yet how to deal with these numerous crash problems that appear to concern so many of us?

For the benefit of French people, here is a screenshot of my setting to partially alleviate the problem (for instance, when coming out from sleep mode). Still, from time to time, starting up the system in the morning will bring that problem again.


screenshot-mac-21.png


Please note that the setting “Empêcher la suspension d’activité…” (“Prevent computer from sleeping…”) has been checked. But problems will remain…

If that could be relevant, my system is an iMac (Retina 4K, 21.5-inch, 2017) with Catalina 10.15.4 (19E287).
 
I have been experiencing this crash ever since I installed MacOS 10.15.4 on my 16-inch MBP. My wife has an older MBP running MacOS 10.15.4 and she has had zero issues. I did a fresh MacOS install on my MBP and this is still happening without me installing any third party software. Therefore it CANNOT be caused by third party things like Dropbox etc. My MBP restarts ~10 times daily.

It seems to be more common when my MBP is plugged into an external hub, but still happens even when it's not. I have been sending reports to Apple now for one month!!!

This is ridiculous. It's seriously making me consider switching back to Windows, which I left 12 years ago.

I hear yah... I just sold my late 2013 mac pro that has this issue. My other macs (mac mini & macbook air) doesn't have the issue.
 
Hi guys,

Here one with MacBook Pro Retina 2012.

I have the same issue (reboot by watchdogd) and used the disabling power nap solution. Today, Xcode finished the Archive process without the reboot issue. I will see next attempts...

Screenshot 2020-05-01 at 21.04.55.png


The issue is raised when the computer is compiling using Xcode and screen shuts down due inactivity. Then it reboots itself or when I touched the keyboard or mouse.

I'm planning soon to acquire a MacBook Pro 16" and I'm afraid to go worst with it :(
 
Just to add to the picture...

Late 2012 MacMini. Started doing the random restarts or not coming back from sleep since 10.15.4 Supplemental update (19E287). No fancy GPU needed here. And of course it's always an external monitor :) .

After reading this looking to drop back to at least 10.15.4 non-supplemental or 10.15.3, which seemed perfectly stable on my setup. Have been trying all the sleep related power settings for fun without success.
 
Looks like AppleGVA itself can now cause those freezes and panics in combination with several GPUs on the latest Catalina releases. But Navi GPUs definitely are one of the GPU architectures that are guaranteed to trigger this issue. But whatever it is, it's beyond hilarious Apple doesn't manage to fix it (along with many other issues and bugs they just ignore). Again: Bug reports regarding this specific issue have been submitted to Apple ever since they first introduced Navi GPU support in a beta back in late 2019.

I have myself submitted a bug report on this crash over hundred times. I assume other users have done something similar. It is so disappointing Apple has not managed/bothered to deal with this.

I had a similar panic today on my 2013 Mac Pro with Catalina 10.15.5 beta 3. I made the setting change suggested by Schmov17 in post #215 and I haven't had the issue again yet (knock on wood). I tried to reproduce it using the steps in the first post and it's good so far. The video is playing in loop in the background.

Code: 
panic(cpu 2 caller 0xffffff7f9dc4fad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds
service: com.apple.logd, total successful checkins since wake (410 seconds ago): 42, last successful checkin: 0 seconds ago
service: com.apple.WindowServer, total successful checkins since wake (410 seconds ago): 30, last successful checkin: 120 seconds ago
