Choose declarative update management before rebuilding macOS update policies

Source facts

For macOS 14 and later, Microsoft recommends declarative device management for installing a specified update by an enforced deadline. The source explicitly advises against MDM-based software-update settings on those devices because Apple deprecated that policy mechanism. The DDM settings are available through Intune’s settings catalog, with the device handling notification, download, preparation, and installation. Microsoft Learn.

Applicability

Review the management mechanism before rebuilding update controls for Intune-managed Macs. Identify the actual OS population and separate any older systems that need their own current support and servicing assessment.

DSE recommendation

Have the Mac administrator map the intended target update and deadline to the documented DDM settings. Inventory existing update assignments before introducing the replacement, and decide how their transition will be tested. Do not reproduce the source’s older MDM configuration examples as the new design for macOS 14 or later.

Verification

Use representative supported Macs to observe the update offer, user notifications, deadline behavior, and installed result under the approved DDM configuration. Record which old settings remain and why, rather than assuming a new profile silently retires every previous assignment. Validate required applications after updating and retain any unresolved servicing exceptions before extending the design.
