I cannot upgrade MacOS Sonoma to Sequoia. Update process silently reboot PC at the beginning of installation.

Hi all.

Recently I managed to boot into my MacOS Sonoma PC based on Ryzen 7700 CPU and MSI x670e gaming plus wifi.

At first glance everything works fine. Network, Audio, Apple store etc.

 

So I decided to upgrade it to Sequoia version.

MacOS update center always offered it.

So it downloaded Sequoia update in System\Updates  and hit "Update"

However at the beginning of update, Still in MacOS GUI (1/5 of progress bar) my computer silently rebooted. No error displayed. Nothing.

After that it normally booted again and again offers update to Sequoia. Like nothing happened. But it didn't remember that I already started update.

So it was not normal reboot as part of update process.

 

Anyone has idea what could be wrong?

Where to look at?

 

I have SecureBoot disabled in config.plist MISC\Security

Did NVRAM reset several times.

Every time exactly same symptoms. It will reboot update process at the same place. No progress made.

 

Thank you.

Appreciate any thoughts.

Does an install disk appear after the first reboot and does the installation continue from there?

[Andy_rwalker]

No. Install disk does not appear in OpenCore boot picker and installation does not continue from there. It looks like accidental reboot which happens during installation. Like if I press reset button during update process.
