Since installing Catalina yesterday, multiple crashes from userspace watchdog timeout

I ran through all the application in the "Apple, About this Mac, System Report, scroll down to applications under the Software section" described by Toulouser (Thanks by the way!).

I have only 64bits app, so not coming from a 32bits app on my side.

I installed 10.15.1 on my

MacBook Pro (15-inch, 2019)

2.4 GHz 8-Core Intel Core i9

32 GB 2400 MHz DDR4

Radeon Pro Vega 20 4 GB

Intel UHD Graphics 630 1536 MB

Installing the update solved the problem for me. Now I am running with 3 monitors and I left it overnight with the power on and it didn't crash.

i'm using MacBook Pro (Retina, 13-inch, Late 2013), updated to MacOS Catalina version 10.15.1 2 days ago, since then i cant shutdown nor restart my macbook. I dont use any monitor extention. pls help

May I suggest that the 32 bit apps can be found in the Legacy Software section in the Mac's report. Acrobat in your screenshot may just need an update to run smoothly in macOS Catalina.

The best way to see if the problems come from an app that is a complementary 32/64 bit runner, is to make a second administrator account (note these apps are not marked incompatible in Applications). After that, logout from your initial admin account and login with the new account. I'll bet you won't be seeing the errors and crashes anymore.

Once logged in with the new account, identify all apps that are from Identified Developer including those labeled as Dowloaded From Internet and check to see if there are any updates available for them online. Some third party apps fail to update or upgrade properly after macOS Catalina upgrade. However, if an app does not have update available to run on macOS Catalina, it is preferred to be uninstalled - just visit app developer's page to find out how the app can be properly removed or, deinstalled.

Hey guys,

as I mentioned in my previous posts I suspected that in my case the crashs were caused by the Intel Power Gadget app, even though the app is 64 bits.

Since one week I stopped using it and I have had no more crashs, so problem "solved" at the moment on my side...

Hey guys,

in a previous posts I suspected that in my case the crashs were caused by Elgato Dockstation Pro.

I've found an Elgato 32bit app with Etrecheck.

Since one week I deleted it and I have had no more crashs.

I get this crash when I have my two 4k monitors connected to my 2019 iMac (shortly after it tries to go to sleep). I no longer get the crash after I disconnected them. Unfortunately none of the other suggestions on here helped.

Never had this issue before upgrading to Catalina.

So running a video on the external monitor works for me!

I created a small black 2 second video to loop using VLC here: https://www.dropbox.com/s/vl8774o900cvkda/Black%20Square.mov?dl=0

Hope this helps until Apple gets this fixed. :)

Same problem here.

Macbook pro 15' 2014, 16GB, 1TB ssd.

Computer hangs with a unresponsive beach ball, then restarts itself and the error report says problems with Watchdog.

This happens to me since I installed the second Catalina OS update (10.15.1). I can force this to happen by launching a high CPU consuming python process from terminal. It hangs after about one hour of processing if unattended (with jolt of caffeine enabled to avoid auto sleep). When using the mac simultaneously with the process, the hang is less predictable, but it happens eventually. Once a day at least. The symptoms are the same: unresponsive beach ball, touchpad movement responsive for a while (no left or right buttons working), then loss of movement and I have to force restart.

I've just unistalled a cpu temperature monitor, because while running this process temperature always elevates and maybe this fun control program has something to to with the hanging. Still trying to learn exact symptoms. In my case only the laptop monitor. Never saw this problem by using monitor + apple TV mirroring.

Same Problem here... !

I've removed second monitor. Problem is still there.

I had two 4k monitors attached to a CalDigit, I did go through and uninstall the 32 bit apps and it seemed to help. But now it's back. I'd be curious what type of connection did your second monitor have.

My setup is this: 1 4K through USB-C on Caldigit Port Hub plugged into the USB-C on the macbook pro 15". A second 4K using display port ( doesn't have USB-C) plugged into the Caldigit Hub as well. And then I usually have my laptop open using that monitor on a side laptop stand. So three in total.

Since unplugging the 4k with the Display Port and just using the laptop monitor and the usb-c 4k monitor i don't seem to have the issue anymore.

Thoughts?

Hmm interesting, I had both my 4k monitors connected with USB-C to DisplayPort cables and was getting the crash every time the Mac tried to sleep. I've switched both to using USB-C to HDMI and it seems to have resolved the issue.. Will try this for a few more days.

Thanks for the suggestion!

I have had this in my iMac 2017, retina 5k, 3.4 GHz. No attachments except printer which is off and external Bose speaker which i have connected for years. This crashes started soon after Catalina (currently 10.15.1). My wife notes it 2-3 times per week when waking the computer in the morning, first thing. Called apple. They suggested safe mode reboot. Still happens. Suggested reinstalling macOS. Have not done that yet. They then suggested that it could be hardware?. Annoying.

here are 2 samples of the reports in the last week:

panic(cpu 2 caller 0xffffff7f858ecad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds

I'm getting this too, and I think it may be related to going into screen saver mode. I have had lots of issues related to accessing media from external hard disks on my Mac Pro desktop. Wondering if people seeing this problem have their screen savers set up to access photos on an external hard disk, just to see if there is any commonality.
