Concept app · v0.1.4 · Notarized

Ratatoskr

Shows information and collects input from macOS users, driven by your MDM — dialogs and workflows are defined declaratively in a configuration profile, evaluated DDM-style. Ratatoskr keeps reminding until the goal is reached.

Concept app. Ratatoskr explores what DDM-style, declarative user messaging could look like on macOS. It's signed and notarized, but it's a prototype, not a supported product, and has been tested in a demo environment only, not in production — validate your workflows on test Macs before rolling them out to users.

🪟

Multiple Styles

Window, blocking fullscreen across all displays, Notification Center banner, or a login window notice — whichever fits the moment.

📝

Markdown text, SF Symbols with effects, images/GIF, PDF, video, allowlisted web pages, light/dark variants, multi-language text, and {{placeholders}}.

Input & Validation

Text, textarea, secure, number, dropdown, radio, checkbox, toggle, and date fields with regex validation — each with an ⓘ popover explaining the expected format.

🔘

Button Actions

Open a URL, System Settings pane, app or file; run a profile-defined script as root or the user; fire a Jamf policy event; defer, restart, log out, shut down, or complete the workflow.

🔁

DDM-Style Workflows

Escalation stages, deferral limits and deadlines, completion by button or condition or both, self-healing, expiry, and version-based reset.

⏰

Many Triggers

Login, unlock, wake, boot, network change, a specific network (DNS domain, host, gateway, VPN, SSID), schedules, calendar times, file appearance, app launch, power source, profile change, or the CLI from any script.

📊

Reporting & Logging

CLI JSON output and exit codes, status.plist plus Jamf Extension Attributes, jamf policy -event, unified log, rotating file log, and ratatoskr doctor for troubleshooting.

👻

Invisible Until Needed

No Dock icon, no menu bar icon — Ratatoskr stays out of sight until it actually has something to show.
