Jamf Pro + Intune notes
Jamf Pro
- Legacy MDM software update commands and deferral restrictions are removed in iOS/iPadOS 27. Use the Software Updates and Software Update Settings blueprint components. (source)
- Jamf School: the Devices > Updates page relies on the removed AvailableOSUpdates and ScheduleOSUpdate commands, so it can't update devices that are already on iOS 27. Use Blueprints. (source)
Microsoft Intune
- r/Intune: after supervised iPhones moved 26.x to 27, 'Software Update Enforce Latest' DDM settings showed as failed. One admin said the errors cleared on their own within hours. Another said an app allow list in a legacy Restrictions policy stopped applying and worked again after moving it to the DDM app allow list. (source)
- Legacy iOS/iPadOS update policies and update-failure reports are being removed from the Intune admin center (MC1470869). Migrate to DDM software update settings. (source)
