Computer constantly restarts after updating to Sonoma 14.4.1

How many times has the computer been restarted , by the user, since Sonoma 14.4.1 was applied ?

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.

It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

Does the issue present in this mode ?

Thanks for your input!

I did manually restart the computer a couple of times and that didn’t help.

Then I tried safe mode, and the problem still persisted.

There could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

Download the Application Etrecheck  ( External Link ) directly from the Developer.

The Application is Not a " Silver Bullet "  and is  only a tool to examine the Hardware / Software used on this computer 

This is a Diagnostic Tool that makes no changes to the computer Hardware / Software used on this computer 

The application is free or paid from added features. 

The Report will Not Reveal Any Personal Information.

I also ran Apple Diagnostics, and it returned code ADP000 No issues found.

Running the Apple Diagnostics is fine to do for the very basics of a Hardware check.

What it does not do, is check where the Third Party Software Software and Operating System installed on the computer is the root cause of this computer issues

To get a background on the suggested Etrecheck application.

At one time there was an  Etrecheck Application available on the Apple Apps Store.

Due to certain constrains place upon the Developer by APPLE, the developer chose to remove it from the Store and make is available Directly from them.

This specific application is well known, on these Forums,  as a Go To for trouble shooting and avoiding all the question / answer and question / answer to finally get the issue pinned down.

It is also known and reported by Reliable Sources that,  sometimes APPLE SUPPORT has invoked using this same Developer Distributed Version of Etrecheck application to trouble shot computer issues 

Have the computer evaluated by the Professionals who have the Special Hardware Software and Expertise to diagnose the issue and offer possible solutions

Make an Appointment at the Apple Genius Bar or call 1 800 MyApple and have them evaluate the computer

Other locations call Centres 

 Contact Apple for support and service

Welcome

To Truly have the hardware of machine checked via the Extensive Hardware Tools and Special Diagnostic Tools.

It would require taking the machine in for service

Not popular idea I know.

But expensive kit like this, I would not fool around and depend on the Builtin Apple Diagnostics to determine the hardware health

Not to labour on but have seen people use the same Builtin Diagnostics when getting a " Volume Mismatch " on every boot-up

Come to find out in some of their cases, a RAM Model had failed and not picked up at all

FYI, I found this thread on github. It's not directly related to that app, but it appears that this has been happening since macOS 14.4 for a lot of people. There are a couple of work-arounds suggested in the thread, including preventing automatic sleeping of displays.

Thanks for your various posts on this. I'm experiencing the same issue and have tried various changes along the lines of what you describe, though not yet reinstalled my system. I guess I need to do that next. Disappointing. This is the sort of rubbish that forced me away from Windows many years ago. I've never had to do it with a Mac until now.

hi, After update to 14.4.1. happened reboot intermittently every other nights, under sleep mode, when I closed the laptop, I reinstalled the OS, was a clean install, SAME thing, seem no fix, And Apple support ius not HELPING at all.

No fix????? anyone can help??
