Since installing Catalina yesterday, multiple crashes from userspace watchdog timeout

Since I installed Catalina yesterday, I have had around five crashes with the error:


panic(cpu 6 caller 0xffffff7f8879cad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds


Any solutions. iMac Pro had been operating fine before update. Only apps running at the time were Chrome and TimeMachine backing up to a Drobo 5N2 (plus of course background apps like Google Backup and Sync, Dropbox, etc).

This happens to me reliably when i have an external monitor connected though a docking station and system is idle. If i have a video or other non static content displaying on the external monitor, my MacBook Pro I9 does not crash. This is new for Catalina and same configuration did not crash on Mojave. Need a fix...

For those of you who are experiencing this issue and using a CalDigit TS3 plus hub there are good news. Last January 6th 2020 CalDigit released a firmware update for this device that seems to fix the issue on my MacBook Pro 15" with Radeon Pro Vega 20 + 2 external monitors under macOS 10.15.3. Since then I haven't experienced more reboots when the screensaver was on.

Sad that Kernel Panic is still there. :(
I think it's pretty standard that more or less every ”dot” update to MacOS includes new graphics drivers – has been like that for years. :)


Francisco-Silva:

What is this Apple? please!?

Please fix this I can't work like this, every my mac crashes making loose so much time restoring my development environment again!

I have 2 external monitors directly connected with 2 single USB-C cables to each monitor and 1 USB-C for the power

Did it stick? How long have you been stable since the update? 🙂

Thx for sharing! Yeah: not deterministic in appearance: something gets stuck and blocks the kernel userspace for more than 120s. Hope a 10.15.4 update comes soon... for now i will default to mojave. Please, let’s update ourselves if any of us tests something that works, or figures out if a specific app is responsible for this...

I haven't seen the crash since 10.15.3 either, but maybe just luck so far? Anyone still seeing the problem have the possibility to try the 10.15.4 beta that's now also available to the public?

I've seen uptime of 10 days without a crash with the .3 release. I've also experienced 4 idle panics in one day with the same version.


If comment about the second thing, my post will be removed 🤷🏽‍♂️.

The crashes completely stopped for me. I was prepping my system to upgrading the internal hard disk, so I updated firmware and backed up, booted Command-R, and ran disk utility first aid. I can't say what fixed the problem, but it hasn't happened in over two months and it was happening every day. If I let my computer sleep on it's own I got the panic crash. If I put it to sleep manually I didn't get the crash. But since running all those system level updates, the problem has disappeared. It hasn't crashed in weeks.

Using Catalina 10.15.3 on 2013 Mac Pro.

What is a bit puzzing it that I've had zero crashes like the one described in this thread using Catalina on my work computer which is a MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports). I usually run it closed via an external display connected via the USB Type C/Thunderbolt 3 port on the computer using a Type C to DisplayPort cable.


And so far no problems on Catalina 10.15.3 on the computer at home with a RX 5700 XT graphics card, but like I've said maybe just luck.


I use both computers more or less every day and put them to sleep and wake them up several times a day.

Aha, I guess you're right – not allowed to comment on beta releases. At the same time it would be helpful for both the users and Apple if we could do so, one would think. 🤔


Yeah, of course it would, but Apple's dedication to secrecy is all-powering. Let's move over to the Macrumors thread: https://forums.macrumors.com/threads/constant-kernel-panics-userspace-watchdog-timeout-no-successful-checkins-from-com-apple-windowserver.2222878/

Hey TheFaust,


Not all of these posts are about the Beta. My post, which was removed, only said that I had installed the Beta from the release of 10.15.3 (which I also had issues with) and still had issues. I wasn't complaining, just responding to someone else's question. That is not discussing or complaining about the beta. I have tried to work with Apple and they have been absolutely useless, which I why I am following this.

Apple has become really embarrassing. I used to be so excited.

After months and 3 updates, no solution in sight.
