We also have had issues with the macOS MDM software updates. We send via SoftwareUpdate, not the Kiosk. We get about a 40% return of actual successful installs. The biggest issue for us has been that the update can kick off without any warning to user. Using the Rollout Plan on FileWave Anywhere seems to help at least keep the restart damage to off-hours but the behavior is wildly inconsistent. Some users get notifications and options to install/try later. Others get no notifications but the update is sitting ready in the Software Update preference pane, and the some just get restarted. Overall not a great experience for our department or the end users. We have been heavily communicating with users to install updates via the Software Update preference pane and once we got everyone to 12.6.2 that has been working well to get users up to Ventura via Software Update (as a standard user). We are testing Nudge to use going forward to give our users better notifications and timelines to install updates. A couple things that helped us get to 12.6.2 were: 1 - removing the software update plist from the Managed Users folder (/Library/Managed Preferences/com.apple.SoftwareUpdate.plist) there is also one of these files for each user in that folder. 2 - restart and immediately check for software updates and install right away (often used in conjunction with #1, but sometimes just a restart gets what you need).
