Since installing Catalina yesterday, multiple crashes from userspace watchdog timeout

After a week without crashes, yesterday two new crashes. Starting with no Elgato Dock Pro connection (and two monitors connected directly via Usb-C) no bad events from yesterday. I also starting to suppose that the problem appear when I move my wireless keyboard and trackpad in a different position (a little away) on my office desk.

I worked the entire day Yesterday with multiple USB-C devices plugged-in (iPad, iPhone, hard drives) without any problems at all.

This morning I open my sleeping MBP, plugged my external Hard drive, and it crashed.

I do not know which chain of event is provoking it but I think we should just wait for 10.15.1 and hope it solves it because it seems difficult to understand what is causing what...

I had mulitple monitors, google, chrome, outlook, and Time Machine. Co worker has same setup except he doesn't run time machine and he has not experienced the issue. I'm wondering If Time Machine is the culprit?

I have starting having kernel panics after the last update to Catalina. I'm on a Macbook Pro (retina, 15inch, Mid 2015), running 10.15.1 (19B77a). The panics seem to happen when I'm away from my machine. I have had a couple of system freezes while actively using the machine, which required a reboot, but I had chrome open with a lot of tabs, so I attributed that to Chrome.

When the panics happen, there are no external devices connected.

I have seen this one several times (note, I do not have a USB card reader)

panic(cpu 0 caller 0xffffff801ca279d7): "com_apple_driver_AppleUSBCardReaderInterfaceNub::setPowerState(0xffffff805488dc00

and then this morning I saw:

panic(cpu 6 caller 0xffffff7f8b6edad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds

which led me to this post.

As I type this, I see the notification that there is an update waiting, so I will be installing that in a few minutes, and I will try to remember to come back here with an update after.

Anyone else notice this in the crash report?

I ran the update this morning. I don't recall how long it took, so let's call it 9am (one hour after my original post). It is 3pm now, and I have not had any panics or reboots.

I am now on 10.15.1 (19B86a). I have not had a chance to put it to work (with Chrome and all), so I will continue to play with it, and reply here again if I have any more issues.

So far, I have not had any issues with Catalina after the last update to 19B86a. I've been away from it for extended periods, used chrome with tons of tabs open, all of which would have caused kernel panics or freezing/laggy usage previously.

Hopefully this works for others, as it seems to have done for me

Hello,

juste happened again, on my MBP 15" 2019, macOS 10.15

It has been 3-4 times it happens when I am launching Intel Power Gadget, that is monitoring CPU activity and temperature.

It seems not being always the case, but I will stop using it until further updates.

Some of you are using this little utility tool also ?

I had the same problem with my iMac, and after resetting the NVRAM, it seems better.

To perform the NVRAM reset , at power-up press, Cmd-Opt-P-R ( all 4 keys at the same time) machine will play the boot sound( twice) and release the keys.

Hopefully you find this helpful

Same here.

I have a MacBook Pro mid 2015, which suddenly restarted while being unused for few minutes. Only app running was Chrome, no external display connected or whatever. This is the first time happening since installing Catalina.

Hey Cooter 1234,

Thanks for your suggestion but I have already tried many times everything : fresh reinstall, NVRAM reset, SMC Reset, cmd+R and disk utility ...

It does not change, and giving all the testimonies in this thread seems to be due to some app creating chaotic behavior with Catalina, maybe due to the mandatory 64 bits.

I just identified that in my case the app Intel Power Gadget seems to be a common factor in all my crashes.

Fresh install of Catalina on a 2019 MBP 15 Vega 20. Just upgraded to 10.15.1. Attached to a CalDigit TS3 dock with two 4K monitors. Crashes about 10 minutes after activating screen saver. Seems worse/happens faster after 10.15.1 upgrade(?)

I just upgraded to 10.15.1 have CalDigit with 2 external 4k monitors. Get up walk away for a few minutes, crashes. If I wait long enough I come back to a login screen requiring password after a restart. If I catch it this is the progression: Cursor is unable to click anything. Cursor Freezes. Fan spins up hard. Restarts.

Happening very frequently since 10.15 upgrade. I will try putting it to sleep on purpose until this is fixed. Very frustrated with support as I know they know something is up yet they try to run you through all the boilerplate diagnosis to figure out the "user caused" issue. How about stop putting out crap software. RIP Jobs I know you're turning in your grave right now.

I'm on macOS 10.15 (19A602), I believe a second patch is currently rolling out which I haven't seen pushed to my machine yet. I'm on a CalDigit with 2 external 4k monitors also. I've had the same idle crashes as well as a few in use crashes where the mouse cursor will still move but everything is essentially locked and I have to power cycle. I started digging in down the 32bit app rabbit whole. AWS workdocs app was showing up in the crash report. I pulled down a fresh install of that from Amazon, and also I still had caffeine running which is 32bit. I had some old Epson scan software (32bit) that wasn't running but still sitting in applications folder. After removing caffeine and 32 epson software and downloading new instance of AWS app, I've been stable for 2 days now (I cringe even saying that but hope it persists). I'm not sure which of these helped but I'd venture to guess it was 32bit caffeine app that is clearly no longer supported on Catalina. Hope that helps.

Apple, About this Mac, System Report, scroll down to applications under the Software section, and then I sorted by the "Obtained from" column and clicked on each app that wasn't an apple app. There's a kind field that designates if its 32-bit, 64-bit, or both. Some of the websites say there's a kind column you can look at in the system report but I only four columns "Application Name, Version, Obtained from, and Last Modified. So I just clicked on each app and looked at the details
