- PNPackara – Native macOS GUI for signing, notarizing, and stapling DMGsMar 2026 · ▲5
I kept copying the same shell script between projects every time I needed to ship a Mac app. It wrapped codesign, hdiutil, notarytool, and stapler into one flow. Eventually I turned it into a proper app. Packara runs the full pipeline in sequence with live log output at every stage. Notarization credentials stay in Keychain and are never passed as CLI arguments. There's a 7-day trial, $9.99 one-time after that. Site: https://packara.techfixpro.net
