A swiftDialog and LaunchDaemon pair for “set-it-and-forget-it” end-user messaging of Apple’s Declarative Device Management-required macOS updates
Overview
While Apple’s Declarative Device Management (DDM) provides Mac Admins a powerful method to enforce macOS updates, its built-in notification tends to be too subtle for most Mac Admins.
DDM OS Reminder evaluates the most recent EnforcedInstallDate entry in /var/log/install.log, then leverages a swiftDialog-enabled script and LaunchDaemon pair to dynamically deliver a more prominent end-user message of when the user’s Mac needs to be updated to comply with DDM-configured macOS version requirements.
