How to Digitally Sign an Installer Package

Category : Technology/HowToDigitallySignAnInstallerPackage.txt

After using the Packages app to build my MySQL and Postgres installer packages, this is how I “looked into” them to see how they’ve been built and make any last minute edits, and then digitally signed them with my Apple Developer ID Installer certificate:

In Terminal.app,

(1) cd to the directory with the built .pkg

(2) pkgutil --expand PostgreSQL-Installer.pkg output/

(3) do any edit of the distribution.dist file in output/

(4) pkgutil --flatten output/ PostgreSQL-Installer.pkg

(5) productsign --timestamp --sign FAEEV5252R PostgreSQL-Installer.pkg PostgreSQL-Installer.signed.pkg

where FAEEV5252R is my Apple Developer ID.

And then 

(6) spctl -a -v --type install PostgreSQL-Installer.pkg

to check that the signing is OK and that it won’t be rejected by macOS’s Gatekeeper.

And that’s it.
