iMac keeps crashing after Catalina upgrade

I have a 2019 iMac (Core i9, 64GB of RAM, Radeon Pro Vega 48, 2TB SSD) that I upgraded to Catalina. I thought everything was working fine until I stepped away from my computer for about half an hour and came back to the log in screen; upon logging in, it said my computer had restarted. Submitted the crash report to Apple. I thought it was a glitch. Kept working, then later on, same thing happened. Stepped away, and came back to the same thing. Submitted the crash report to Apple again. Then it happened again. And again. And again. Today, same thing; computer keeps crashing, over and over and over.


I've changed nothing in terms of hardware or software between yesterday and today (or since I set up this iMac a few months ago), except for upgrading to Catalina. Under Mojave, there were no issues.


If anyone has any idea how to resolve this, that would be greatly appreciated!


Below is one of the many, many crash reports, but they all look similar in terms of it seeming to be related to com.apple.WindowServer:

If you have the same issue as OP (the machine crashes reliably when you leave it alone for about 10 minutes, you probably have multiple external screens), I've made some progress. If your problem isn't like that (most of the comments here don't seem to be) YMMV, but I wouldn't expect this to help you.


The short version is, that I've made the crashes stop by deleting my Google accounts (and a weird looking null 'Contacts' account that was in the same list) from System Preferences | Internet Accounts. I'm currently re-adding my email addresses one by one to see if the crashing starts again. But there are thousands of mails to download, so it'll take a while before I can say whether that's safe.


I came to this conclusion by installing a fresh version of Catalina next to my main install. I couldn't reproduce the issue in the fresh install; no crashing. Then I gradually added apps and services one by one, leaving the machine alone for a while after each thing. If I came back and the session was still alive, I knew that app or service hadn't caused the problem. The crashing only started when I enabled my email accounts on that Preferences screen. Deleting them stopped the crashing (disabling them wasn't enough).


I hope this helps somebody out.

You should have exported the photos as full size jpgs or as originals to folders while still in Catalina. Then import into Mojave photos. Similar with videos. This is because Catalina reprocessed the photos library.


Music mp3 and m4a folders can just be moved from the itunes media folder in Mojave, clean up the various index files then added back in File, Add to library.

Cant help with Podcasts or TV but think along the same lines.


However anyone who actually did it can add their experiences

Too many people signing up to Beta program for bragging rights and not feeding back problems through correct routes. What are Apple supposed to infer from those statistics?

What makes you think people that discuss in here *aren't* also reporting their experiences to Apple? I've sent 10s of gigabytes back myself through Feedback Assistant since starting with Catalina.


Also, since it's beta software, I'd expect the OS to be reporting back more about usage and stability than the releases. I would expect to be signing away some degree of privacy in the beta EULA, precisely so that it can inform bug-fixing and development. The result should really be that just having people using the software is helpful to the process.


Whether writing in here helps the writers in any real way, is another matter entirely of course 🙂

I have a MacBook Pro (16 inch, 2019) for a week. If I knew that, I would never spend $ 2,799.

The way is to keep using my old Macbook Pro 13 "running Mojave.

Frustrating when it comes to an Apple product.

With so many people having to get logic board replacements that don't help, and confirming that fresh installs don't help, it feels like Apple owes us an apology. Half a year without being able to use one of the most basic peripheral add-ons is crazy.


I've been a loyal Apple user for decades, and I'm currently sitting with a maxed out iMac Pro that I can't use for my daily work. This is the issue that's finally breaking me.

I have a 2012 MBP that I spent nearly 5k on when it was new. It literally was the best one you could buy. I justified the expense because it never crashed and that I wouldn’t need to replace it every couple years. Recently I was in the market for an iMac Pro looking to spend about 6k but decided not to after my MBP turning into a paper weight since Catalina. Will wait until they get the issues worked out and if still crashing then I’ll just build a nice PC and save the cash.

My iMac was rendered unusable so I bought an Intel NUC8i5BEH and a 4K monitor. Windows 10 is rock solid - much more so than macOS these days - and I'm enjoying using it. Better still, the NUC itself was £375 ($452) so to upgrade in the future that's all I'll need to replace. It attaches to the back of the monitor and comes with a VESA mounting plate. I love it! My iMac is now in a cupboard. What a waste of money that was.

Even with a fresh install of Catalina the restarts due to kernel panics continue. I dont know what to do.


Now I tried to remove one of two RAM sticks (2x 8GB) to observe if the restarts will stop; I had did it some time ago and the machine runned well, but I put the stick back again later


I will keep you updated, even know that this solution can't be applyed to everyone


P.S.: Restarting has already corrupted the data on my external hard drive several times.


Fix it NOW Apple!

Hi,


Have your reported the problem to Apple?

If you have AppleCare have you raised an issue? and if you do, raise the problem again and again.

If you joined the beta program did you send the issue in the correct feedback app?


Just asking because Apple do not care about this channel, so publicly complaining here will not reach anyone and sending crash reports don't seem to do any good either.

They only monitor this forum if you say something you're not supposed to about the beta program, otherwise it's not considered 'official'.


The other option is everyone on here to start complaining very loudly on something like Twitter every time you have a crash and make sure you also send it in a DM to Apple.


This has been going on too long now.


Good luck.


Steve

Y'all resolve this issue?


I'm running a mid-2018 MBP 2.9 GHz 6-Core Intel Core i9, Radeon Pro Vega 20 4 GB and am having the same issue since upgrading to Catalina 10.15.3.


While I can't confirm that it only happens when I use my Caldigit T3 dock with one monitor connected via DisplayPort, it does seem more frequent than when I have them connected through two different Mac and Caldigit HDMI/Displayport adapters.


I spend my days editing documentaries with tons of footage but with proxies so while there is a Thunderbolt RAID attached, it's not doing crazy work...


I've been monitoring RAM and CPU usage and nothing seems too out of whack - my suspicion is that the GPU is getting overheated between the 2 monitors and Premiere and that's what's causing the issue.


Any thoughts?
