Gravity DMG - Sign, notarize, & design DMG packages for your macOS apps

Hi Product Hunt! 👋 I’m Bob, the maker behind Gravity DMG. As a macOS developer, I’ve always found the "last mile" of app development, packaging and distribution, to be the most frustrating part. You spend months building a beautiful app, only to have the installer look like a generic folder from 2005. I built Gravity DMG to turn that headache into a "one-click" workflow. It’s an all-in-one tool that handles the heavy lifting of the Apple notarytool API while letting you create stunning, professional installers using curated layout presets and assets. Key Features: • Visual Styling: Instantly apply high-quality backgrounds and layout templates to your installer. • One-Click Notarization: We handle the entire Apple notarization process for you. • Secure & Local: Your credentials never leave your machine; we integrate directly with your system Keychain. • Smart Compression: Choose between UDZO, ULFO, or UDBZ for the perfect build. Exclusive Product Hunt Launch Deal: We have officially launched Gravity DMG at $14.99 today. However, to celebrate our launch here, I’m offering a 33% discount exclusively for the community.
