If I build a simple .pkg and sign it, It can be installed without problem. If I include a reference to an external package (Custom Path / HTTP URL), it doesn't work.

This email sent to site_archiver@lists.apple.com Sorry, but I think this is good news. This way it is not possible to bypass Gatekeeper by including some package that has not been part of the initial signature. After all Gatekeeper has no means to verify that your external package is still the same as it was when the including package has been signed.
