iMac keeps crashing after Catalina upgrade

It's less frequent, but it still happens. I'm currently up to nearly a week without a crash with 'Automatic graphics switching' turned off. YMMV. Quite an achievement for a machine so absurdly expensive (2019 MBP w/ Vega20) /s.

My mileage just varied. It crashes with those settings too.

I don't get anything when I run that command but I'm still getting the panics approx. every 10 days since 10.15.3 (and prior to that much more frequently despite a logic board, HDD and power supply replacement):

I have been sending crash reports since upgrading to Catalina. This has been ongoing and relatively unchanged since the upgrade. I am sure others have also been sending in crash reports too. This leads me to the conclusion that either Apple does not view the reports or they cannot resolves the issues causing Catalina to hang on nearly ALL compatible Macs.

I have just submitted my 100th crash report since I stared keeping a copy as a text file as well as sending to Apple.

Twice already this morning on my MBP :/

Radeon Pro 560 in my MBP

Part of the stability of Apple products compared to WinPC is that there is a known set of hardware, so easy for Apple to test against every commercially available combination, rather than the trillions of combos of motherboard, cpu, gpu, SSD, RAM etc etc

At least on my Windows machine I can go direct to the vendor and search for an updated driver patch, or simply roll back that specific part to a known working state.

Apple products "just work", until they don't - at which point you are utterly borked.

I am having a similar issue with my 2019 iMac (Core i5, 24 GB of RAM, Radeon Pro 570X, 1TB SSD). Since updating to MacOS 10.15.4 Over the last week my Mac has restarted a number of times while away from the computer and frozen a couple of times while working on it. Very annoying

Yes! I have a 2017 macbook pro base model, and it was working perfectly fine until catalina. Then it started having kernel panics, massive perfomance drops, and app crashes all the time. bring back high sierra pleaseeeee

I have this problem on only one machine-- a late 2003 mac pro. My two other machines-- mac mini and mac air-- work fine with Catalina. It just doesn't make any sense. My mac pro is basically a paper weight now. I can't use it for critical work since it'll freeze now and then.

@McGroaty Thanks. I'll give that a try and report back. FYI, you cannot fallow links to download mojave from the app store from firefox. It will say it's not found. Either the app store, or the app, not sure. From safari they work fine. Just in case any one has that issue.

I have the same iMac with the same specs, does the same thing. Crashes constantly, always get panic errors, or kernel panics. Adobe after effects crashed 10 times a day, I spent 5 grand

same here, bought a brand new macbook air 2020, was stupid enough to install 10.15.4... now it get 2-4 random kernel-panics a day, this issue is now months old.... no word from apple yet... no sign of help or change.

Mojave sucks, Catalina sucks and Adobe After Effects sucks, all 3 cause my top end iMac to crash 10 times a day. I gave up and installed boot camp and am running windows 10 with after effects. I understand the iPhone is now the most important part of Apple but they have plenty of money to keep the Mac OS up to par.

Mojave and Catalina, both have constant panic and kernel attacks combined with adobe after effects, I don’t know what it is or who is to blame. A normal working day for me is 10 crashes. Spending at least an hour rebooting over and over again. I don’t want a new OS version with a Slick California name, I just want it to work. Ready to switch to windows... I spent over 3k on this top of the line iMac and it’s garbage.

I have Tweeted OSX rumors and they have looked into it and don’t have a solution. I think by this point with no acknowledgement from Apple that it’s a safe bet Catalina is a wash. One can only hope the extreme stability issues get resolved in the next version of Mac OS X
