## Executive summary This Jamf briefing summarizes Apple OS 27 and its enterprise-focused features: Declarative Device Management (DDM) becoming the standard, native allow/deny binary controls on macOS, unified privacy management and permission prompts, centralized credential declarations, package uninstall for full software lifecycle, Platform SSO/IdP-based login with modern authentication flows, extended real-time status channels and fleet hardware monitoring, and expanded Apple Business services — all framed as management and security improvements rather than an active threat.
