About DuoUpdater

Keeps macOS apps up to date through each app's own release channel — Sparkle, App Store, Homebrew, GitHub releases, or a per-app recipe against the vendor's own endpoint — with signature-verified installs and rollback. Pure Swift.

How to install DuoUpdater on a Mac

  1. Get OpenDMG. It is a free app store for open source Mac apps. Download OpenDMG.
  2. Search for DuoUpdater and press Get. OpenDMG downloads version 0.5.23 from jizhi0v0's own GitHub release.
  3. Open it. The download is checked against its SHA-256 fingerprint and its signature is checked on your Mac before it lands in Applications.
