Build beautiful, notarized DMGs in seconds. Gravity DMG is the all-in-one tool to sign, notarize, and package macOS apps with professional elegance. Stop fighting complex command-line tools like notarytool and hdiutil. The Autopilot Workflow: ✦ Visual Styling: Curated layout presets ✦ One-Click Notarization: Native Apple API ✦ Secure & Local: System Keychain integration
Gravity DMG offers build templates with dynamic variables (${VERSION}, ${DATE}, ${APP_NAME}) for automated output naming, supports multiple compression formats (UDZO, ULFO, UDBZ), and enables parallel processing to create organized, repeatable release pipelines.
Gravity DMG automates the entire signing and notarization workflow in a single pass: automatically enables Hardened Runtime, preserves entitlements, performs pre-flight inspection, and handles Apple's notarization process—eliminating manual command-line steps and configuration errors.
Gravity DMG provides a visual drag-and-drop editor to create branded DMG installers, automatically signs app bundles with Developer ID, and handles the complete notarization pipeline using Apple's notarytool API—eliminating the need for command-line tools and reducing distribution time from hours to seconds.
Gravity DMG offers a one-time $14.99 lifetime license (not a subscription) that includes unlimited builds, commercial distribution rights, priority support, and all future minor updates and bug fixes for the current major version.
Gravity DMG integrates directly with macOS Keychain to securely store all credentials, API keys, and license information on the user's machine, ensuring sensitive data never touches configuration files or text-based storage.
