Imac keeps shutting down/restarting

My Imac, latest ios (Sonoma 14.0), 24" 16GB ram, 2021, keeps shutting down or restarting.


This started about 2 weeks ago and I had the Imac at my closest Apple reseller as it is still within the warranty. They didnt find any problem with the hardware, but the issue keeps happening. This had started before the latest update, at elast 10 days before, and keeps happening after the update, as well.


I cant attach an error log as it exceeds the 25.000 character limit.


Any body got an idea whats happening here? What can I do? Wipe the system?


Cheers


iMac 24″, macOS 14.0

Hello Ssmdmdm,


When the computer restarts, are you getting the message "Your computer was restarted because of a problem"? If so, you'll want to use these steps: If your Mac restarted because of a problem


If the computer is just restarting without any error messages, then you'll want to go through general troubleshooting to try and isolate the cause.


If you have any external devices connected to the computer (external hard drives, USB hubs, printers, etc.) disconnect them and see if the unexpected restart continues.


Start the computer in safe mode to see if the issue occurs in that mode. If it does not restart while in safe mode, then that indicates the issue is coming from some software you have installed on the computer. If you noticed the issue started after you installed something on the computer, try removing it to see if that resolves the issue.


Start up your Mac in safe mode


Test another user account on the computer. This will help to isolate if the issue is tied to something in your main user account or if it's a system wide issue. You can use these steps to add another user account to the computer: Add a user or group on Mac Once you create another user account, switch over to it then test out the computer and see if the unexpected restart still occurs.


Cheers!
