you've booted in safe mode, and/or reset nvram? haven't seen that message again in a long time now. what other 'staggering' bugs have you experienced in apple's OSes? start a thread, perhaps, see if anyone here can help.This is still a bug for me in Big Sur 11.3.1, on a fresh User profile even. 😡
The amount of bugs Apple ships their OSs with is staggering.
Thanks for chiming in. So I tried cleaning Kext Cache through the terminal and had no luck. Downloaded Onyx, ran the default maitenence, and bingo! No more dialogue on restart. I Will see if it sticks. Only wish I knew what the culprit was. Thanks again!I had the same problem in Catalina, running OnyX maintenance fix it.
It's probably the cleaning of system kext caches, that can also be done from Terminal.OnyX is a multifunction utility that you can use to verify the startup disk and the structure of its system files; run tasks of cleaning and computer maintenance; configure some hidden parameters of many Apple applications; and more.www.titanium-software.fr
Same exact experience here. Also same year iMac only with an i7 though.Just to note, I've started seeing this problem on my iMac (27" i5, 2019) running macOS Monterey (12.0.1).
The only coincidental is that I did see a kernel panic last weekend, but everything seemed fine after that restart…
The last few normal restarts have consistently shown the "You shut down your computer because of a problem" at login.
I will try the Safe Mode boot, and NVRAM reset.
EDIT: tried both Safe Mode boot (which took a few goes to actually activate, and bizarrely only worked with the right shift key) and an NVRAM reset. Neither resolved the error message.
But, as per the tip from @bogdanw , running the 'Maintenance' ▸ 'Run Tasks' feature in OnyX worked a charm; the error message is now gone when I log in to my Mac. Thank you! 🖥😃
Same things for me tooo!!!! I noticed it yesterday when starting up my iMac …. Driving me crazy!!!!Same exact experience here. Also same year iMac only with an i7 though.
Posted above…Same things for me tooo!!!! I noticed it yesterday when starting up my iMac …. Driving me crazy!!!!
also: tried safe mode and the error was gone , didnt show up with safe mode on , restarted it to normal and got the same message starting up iMac AGAIN … ever Since i downloaded the new Mac OS Monterey ….praying there’s an update to fixing this!!! 🙏.
PLEASE if anyone knows how to fix this please let me know ,, THANKS
“Panic attack” is actually the right description As we are not taking about the cause of one crash, but about the irrational macOS behavior that gets scared after every reboot and displays a message about a problem when there isn’t any.The issue might be due to a kernel panic attack.
