DDM OS Reminder (1.4.0)

on GitHub

With quality-of-life improvements for both end-users and Mac Admins alike, version 1.4.0 is what version 1.0.0 should have been from the start

18-Nov-2025

• (Reluctantly) added swiftDialog installation detection
• Added meetingDelay variable to pause reminder display until meeting has completed (Issue #14; thanks for the suggestion, @sabanessts!)
• Added Resources/createSelfExtracting.zsh script to create self-extracting version of assembled script
• Updated Resources/README.md to include "Assemble DDM OS Reminder" and "Create Self-extracting Script" instructions
• Re-re-refactored installedOSvsDDMenforcedOS to include @RGBpixel's recent discovery of setPastDuePaddedEnforcementDate (thanks again, @RGBpixel!)
• Added daysBeforeDeadlineDisplayReminder variable to better align with — or supersede — Apple's behavior of when reminders begin displaying before DDM-enforced deadline (thanks for the suggestion, @kristian!)
• Added Resources/JamfEA-DDM_Executed_OS_Update_Date.zsh script to report the date when the DDM-enforced macOS update was executed
• Removed placeholder DDM-OS-Reminder End-user Message.zsh from ddmOSReminder.zsh; use Resources/assembleDDMOSReminder.zsh to assemble your organization's customized script instead

🆕 Deadline vs. DDM-enforced Restart Date / Time 🆕

Special thanks to @RGBpixel for discovering Apple’s setPastDuePaddedEnforcementDate entry (also in /var/log/install.log), which should now make the past-deadline, DDM-enforced Restart Date / Time shown in the swiftDialog-generated message exactly match what’s displayed in the native macOS notification.

🆕 Days Before Deadline Display Reminder 🆕

To better align with Apple's documentation — as pointed out by @acodega — a new daysBeforeDeadlineDisplayReminder variable allows the Mac Admin to control how many days before the DDM-enforced deadline users will begin seeing reminders. (Thanks for the suggestion, @kristian!)
