# Overview

Declarative Device Management (DDM) is an evolution of Apple's MDM protocol that lets devices apply settings and report status asynchronously, without constant polling of the management server. This improves performance, scalability, and responsiveness for managed macOS fleets. This section explains how DDM works and how to enable it with Intune.

Read the concept overview first, then follow the configuration steps and review the insights.
