iMac keeps crashing after Catalina upgrade

Lol! Absolutely not - of course I'm not 'right' neither are you! I also have a 2012 Mac Mini which is running Catalina without a single problem. All we're saying in this thread is that a certain number of users are having stability issues with Catalina. There are similar posts all over the internet. Are you saying there isn't a problem? Do you know any 2017 4K iMac users who have no issues? Are any of your stable Macs this particular model?

Seeing you read every post, one would think you noticed those having an issue are not limited to 2017 iMacs. What I have is an iMac Pro, two 5K iMacs, a MacBook and a MacBook Air. Some of which others are having an issue with.

Alternatively, give up and move to Windows

Personally, I think you should follow your own advice.

Why the hostility? Are you one of those people who hate seeing any posts which criticise Apple in any way? I have indeed followed my own advice and bought a Windows desktop. I want a resolution to the issues I've been having so I can sell my iMac and recoup some of the money I spent on the Windows machine. Of course I have noticed others are having issues with a range of Macs. A friend bought the latest and greatest MacBook Pro and had the same issues out of the box. I'm really not sure what you are saying, TBH.

I wasn't being hostile.

Nope. I'm just a fan of reality. :) FWIW, I also own two Windows 10 laptops, A System 76 Linux laptop and a Chromebook.

I haven't used FileVault for years. I stopped using it when an older machine couldn't handle video through FileVault, and I had to create a separate account for video.

It certainly wasn't running on my MBP when it starting having issues. But I was making and working with video.

The issue is the bugs in the newest versions of Apple OS. They release to keep people salivating, they don't care if it works right or not. Instead of beta testing, they release, and everyone comes here to complain. You all essentially work for Apple with no pay what so ever.

Poor Beta testing is down to not enough users like you joining the program with decent test plans and proper reporting. Too many users want the latest beta for novelty. What are Apple supposed to think? Thousands of testers and few bugs. If you want to join the Public beta program you can help with the testing.

I've tried all the 'fixes' users in this thread have suggested. None give me long term stability. I have no external monitor, I do not use filevault, I don't allow my iMac to sleep, I have tried clean installs. Once I manage to boot into Windows on the same machine there are no issues at all.

I'm fed up with Apple.

I don't have time to play with configurations and tests. I have to work. Respect timeline. Earn money.

I'm not a beta tester.

I deep clean the mac, disable every 32 bits things, and disable all possibly options that causes bugs ...

My main computer work flawlessly with Mojave and now with Catalina, it's a knightmare.

In office I use a Windows 10 machine too and it' hard to say, but it just work !!!

Apple REALLY sucks right now !!!

I’m wondering, how many of you have multiple monitors crashes and used the public xxxx before the official release?

Could we have been issued a firmware that never got upgraded properly? I had each pre-release before Catalina was final.

For anyone getting kernel panics, are you one of those that used the GA release or something else?

I didn't use any beta software. Just the standard upgrade process. Had a few stops and starts downloading and kicking off the 10.15.0 version, but OK with the 10.15.1 and 10.15.2 version. Then the MBP turned up its toes and cashed in its chips! Never got to 10.15.3. But I was using dual monitors almost all the time, in two different configurations, and a video projector in class. Crashed in all configurations.

Downgrading firmware is possible, but unsupported. People frequently brick systems doing it.

Recovery will not be supported by warranty if they figure out what happened to your machine. If you're lucky you'll just pay for bench time while they use hardware to reprogram the logic board. Or you may end up paying for a new logic board altogether.

I noticed during the initial Catalina update that the machine appears to go stupid/black screen for 10 to 15 minutes. I suspect that certain update operations, possibly firmware updates, were gong on silently. I had the urge to power clear/restart but resisted. The upgrade finally, finally continued visibly. I fault Apple for not making some kind of notification. If I had hit the power button, would I have blown the firmware update? Who knows? I'm glad that I was patient. I do not have crashes. I have noticed that USB devices (printers, scanners, iPhone) sometimes do funny things. Sometimes my backup drive gets lost by TimeMachine, which has never happened before. Is it the USB subsystem? Or the I/O system in general? .... the beat goes on.

Hello,

Three causes of crash here :

1. panic(cpu 2 caller 0xffffff7f87a4bf3f): @/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOUSBHostFamily_Drivers/IOUSBHostFamily-800.80.1/AppleUSBXHCI/AppleUSBXHCITransferRing.cpp:220
2. /System/Library/PrivateFrameworks/PhotoAnalysis.framework/Versions/A/Support/photoanalysisd
3. /System/Library/Frameworks/Quartz.framework/Versions/A/Frameworks/QuickLookUI.framework/Versions/A/XPCServices/QuickLookUIService.xpc/Contents/MacOS/QuickLookUIService

For several years i use my Mac mini as a pro photo editor with creative cloud, very stable with Sierra and High Sierra, when i upgrade to Catalina early January no more work done. Crash after crash, sometimes at restart. Downgrade do Mojave, exactly the same issue. When exporting a job with around 1500 photos, after 30 seconds, crash, then again and another crash, impossible to work. Last night i tried reinstall Catalina and even that i can't do, return error saying "can't remove old version"... come on Apple, you are making pro's and customers lose faith in the brand and switch.
