DMGKitPro

Your app is done. Shipping it shouldn't take another day.

Signing, notarizing, stapling, building a DMG that looks good, and then finding out Gatekeeper still blocks it. DMGKit does all of it for you. Drop in your app and get an installer that's signed, notarized, stapled and checked, ready to share with anyone.

One click from .app to release

Import your .app or .zip, pick DMG or PKG, and export. DMGKit signs it with your Developer ID, sends it to Apple, staples the ticket, and checks signing, notarization and stapling before telling you it's done.

Meet Kit, your release assistant

Something went wrong? Press Diagnose. Kit reads what happened and explains the problem and the fix in plain words. It runs entirely on your Mac, and your chats are never saved or sent anywhere.

Installers that look like you meant it

Design your DMG window with backgrounds, gradients, stickers and text in any font. Preview it in Light and Dark mode, and save it as a template for every release.

PKG installers, done right

Export signed and notarized Installer packages with your Terms, Privacy Policy and EULA built in, in every language you need.

Faster releases for notarized apps

Already notarized your app? Staple Only reuses Apple's ticket instead of notarizing again, cutting export time roughly in half.

Inspect before you ship

Open any DMG or PKG and get a full trust report: signatures, Gatekeeper, notarization, entitlements and architectures.

Automate everything with CLIKit, included free

Sign, notarize and package from Terminal, SSH or CI using your DMGKit settings and templates. It can even run automatically after every Xcode archive.

Private by design

Use a keychain profile or an App Store Connect API key. Passwords stay in your macOS keychain, and DMGKit has no analytics or tracking.
