Gravity DMG

Gravity DMG is a macOS application designed to simplify the creation of professional, signed, and notarized disk images (DMGs) for software distribution. It replaces complex command-line workflows with an intuitive graphical interface, allowing developers to build polished installers in seconds. The tool’s primary purpose is to streamline the final packaging stage of macOS app deployment while ensuring compliance with Apple’s security and notarization requirements.

With Gravity DMG, users can visually design their DMG layout, including custom backgrounds, icons, window sizes, and folder structures, without manual scripting. The tool automates code signing and notarization, managing entitlements and communicating with Apple’s notarization services so that resulting DMGs run smoothly on end-user systems without security warnings. It supports reusable templates, enabling teams to standardize branding and layout across multiple products or releases. In addition, Gravity DMG handles compression, file permissions, and configuration details that are typically error-prone when managed via command-line tools.
