Ventura update fails after download, while "Preparing MacOs Ventura 13.0.1... Then returns to the download prompt I've attempted the upgrade from System Preferences - Software Update - Monterey to Ventura 4 times today. The download completes and then it says "Preparing MacOs Ventura 13.0.1...", Then a window says the computer will reboot in 60 seconds. And when it times out, the system reboots, back to Monterey. And It starts over again with a prompt to download all over again. I'm downloading from the App store this time to see if anything changes. Each attempt requires a half hour while I wait form the software to download again. But something seems to be preventing the installation. I have enabled Content Caching in Sharing preferences as one article suggested. But no change.

It would be suggested to update the Current version of Big Sur to the current version 11.7.6

Attempting to upGrade from Big Sur 11.5 and jumping over all the updates of Big Sur is problematic
