A while back, I discussed how to incorporate installer package signing into AutoPkg workflows. The PkgSigner processor used in this workflow was originally written by Paul Suh and it uses Apple’s productsign tool to access a Developer ID Installer certificate stored in the login keychain.

Like other processors and AutoPkg itself, PkgSigner needed updating to Python 3 when Python 2 reached end-of-life in April 2020. This updating process has been completed, thanks to Nick McDonald. To make sure PkgSigner is consistently using the same Python environment across machines, PkgSigner has also been set to use the Python 3 install bundled with AutoPkg.

For those who need it, I have a copy of the PkgSigner processor available via the link below:
