Gravity DMG is the ultimate tool for macOS developers to package, sign, notarize, and distribute their applications. It provides a comprehensive solution for creating professional DMG packages without the complexity of command-line tools.

The tool features a visual DMG editor with drag-and-drop simplicity and a built-in library of space-themed backgrounds. It offers one-click notarization using Apple's modern notarytool API and secure signing that automatically signs your .app bundle, enables Hardened Runtime, and preserves entitlements. Gravity DMG integrates with the system Keychain to securely store Developer ID and Notary profiles, and provides smart compression options including UDZO for compatibility, ULFO for speed, and UDBZ for maximum compression ratios. Build templates automate output naming with dynamic variables like ${VERSION} and ${DATE} for organized release pipelines.

Gravity DMG works by providing a visual interface that replaces complex command-line workflows. The autopilot workflow guides users through the entire process from packaging to notarization, handling the technical details automatically while maintaining security through local Keychain integration.

The product saves developers time by eliminating the need to fight with codesign commands and failed uploads. It ensures professional-looking distribution packages that maintain security standards while being easy to create and deploy.

Gravity DMG targets macOS developers, indie developers, macOS engineers, DevOps leads, and product managers who need to distribute macOS applications. It requires macOS 13.0 (Ventura) or later and is optimized for both Apple Silicon and Intel-based Macs.
