DMGKit 3.0.0 for Mac
Mac UtilitiesDMGKit, from Fuse Labs, handles the last mile of shipping a Mac app outside the App Store. You drop in a finished app and design how its installer looks, with backgrounds, layout and reusable templates. Then the same app takes care of code signing, Apple notarization and stapling, and inspects the result before you share it. It replaces a pile of Terminal commands and scripts with one visual, repeatable release flow.

FAQs
Who is DMGKit for?
Mac developers who ship direct downloads outside the Mac App Store and want their installer to look professional and pass Gatekeeper checks without fuss.
Can it check an installer someone else made?
Yes. The Inspector opens any DMG or package and reports on signatures, notarization, entitlements and architectures, with each check explained in plain words.
Does it work for team release pipelines?
Templates make releases repeatable, and a companion command line tool is included for signing and packaging from Terminal, SSH or CI jobs.
