Reviews
Built for developers who care how their app arrives.
Early feedback from developers using DMGKit and DMGKit Inspector to make direct Mac distribution feel cleaner, faster, and less intimidating.
“The installer finally feels like part of the app instead of an afterthought.”
Early DMGKit user“Templates alone save a ton of time when shipping updates across multiple products.”
macOS utility developer“I wanted something cleaner than manual DMG work, but still flexible. This hits that sweet spot.”
Direct-distribution developer“The visual approach makes direct distribution feel much less intimidating.”
Indie Mac app founder“A calm release tool. That is weirdly rare.”
DMGKit Inspector testerFAQs
Answers before release day.
Everything you need to know before shipping your next release.
DMGKit is built around .app bundles and DMG-based distribution. Depending on your workflow, you can also work with imported .dmg, .pkg, or .zip files that contain supported Mac release assets.
Yes. DMGKit supports signing and notarization workflows so your final release can meet Apple’s security requirements for direct distribution.
Yes. DMGKit can support notarizing the application bundle first, then packaging it into the final DMG depending on the settings selected for the release.
You can design installers without Apple Developer credentials. Signing and notarization require a valid Apple Developer account, configured certificates, and the correct signing identity.
Yes. DMGKit includes visual alignment and positioning controls so backgrounds, icons, arrows, and overlays can be placed with much better precision.
Yes. You can bring your own background art and build the installer design around it. The current recommended background size is 1600 × 1000 px.
Yes. Templates let you preserve a consistent installer style across apps, client projects, and future updates.
Design and local export workflows can work offline. Notarization requires Apple services, so those steps need an internet connection.
No. DMGKit focuses on direct DMG-based distribution workflows, not Mac App Store packaging or submission.
DMGKit helps make the release stage clearer, but notarization failures usually come from certificate setup, entitlements, hardened runtime, bundle contents, or Apple account configuration.
