The /Library/Preferences/com.apple.SoftwareUpdate.plist seems impervious to being managed via configuration profile (at least on macOS Mojave). While not enforced management, add this script to a Jamf policy and run it on a routine basis such as once per week on scoped Macs.

Enable all macOS software updates.bash

#!/bin/bash

/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist AutomaticCheckEnabled -bool TRUE
/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist AutomaticDownload -bool TRUE
/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist AutomaticallyInstallMacOSUpdates -bool TRUE
/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist ConfigDataInstall -bool TRUE
/usr/bin/defaults write /Library/Preferences/com.apple.SoftwareUpdate.plist CriticalUpdateInstall -bool TRUE
/usr/bin/defaults write /Library/Preferences/com.apple.commerce.plist AutoUpdate -bool TRUE

exit 0

@smr1619 Just tested on macOS 12.4.0 using a Jamf Pro policy and it's working as expected.

Have you tested locally to see if it works? Open Terminal and test individual lines. Then test running the entire script locally. Then see what happens when you add it to whatever management server you're using.

And be sure to close System Preferences completely between tests. Its interface won't automatically update.

Hello, I tested your commands, they work, we can verify it with "defaults read" commands just behind. However, the values, although correctly modified, are not taken into account by the system and the System Settings switches do not move! I think it needs a command behind to force the changes. I tested "Killall Finder" without success. Does anyone have the answer?
