Hey Michael. These are the commands I'm using. They worked with Monterey last year and they work with Ventura this year as well. These commands assume that you're allowing end-users to initiate the installation via Self Service, and that Install macOS Ventura.app is already cached on their machine (I use a separate policy to download the installer silently to compatible Macs that don't have it yet).
Note that the Apple Silicon variant requires you to list the password of a local Administrator account in the command.
Also note that if your users are running this from Self Service, in my experience it can take a while (10-30 minutes) for the Mac to restart while MobileSoftwareUpdate runs in the background. The only indication your users will have as the Mac prepares for the update will be the spinning circle in Self Service, so you might want to give them a heads up about that. ☺️
/Applications/Install\ macOS\ Ventura.app/Contents/Resources/startosinstall --agreetolicense --forcequitapps --nointeraction && sleep 10 && osascript -e 'tell application "Self Service" to quit'
echo <local admin account password> | /Applications/Install\ macOS\ Ventura.app/Contents/Resources/startosinstall --agreetolicense --nointeraction --user itdepartment --stdinpass && sleep 10 && osascript -e 'tell application "Self Service" to quit'
Sure—that policy is pretty simple. I just host the package in Jamf Pro, add it to the policy, and then scope the policy to a smart group that looks for Macs that don't have Install macOS Ventura.app installed.
What method have you been using since the Big Sur days? How's it been working for you?
I believe you can find them from MrMacintosh here: https://mrmacintosh.com/macos-ventura-13-full-installer-database-download-directly-from-apple/
To get the installer these days I just use the following code to grab the latest version of the installer:
softwareupdate --fetch-full-installer --full-installer-version 1.2.3
@jmackbnd Why re-package the Ventura installer when Apple has done it for you: https://swcdn.apple.com/content/downloads/25/16/012-92138-A_KGGGN26YQB/d0kr042ixfvkboeft8qt2i3aclr5b...
