man productsign You have to use the productsign command line tool to sign a package made with PackageMaker when signing it for Gatekeeper (so that required intermediate certificates get embedded). The command line is easy to use. The only inconvenience somehow (in my opinion) is that you have to use a different file name for the output. http://s.sudre.free.fr/Stuff/Installer/Unreleased_Notes/10.8_Gatekeeper.html On Thu, Sep 13, 2012 at 12:00 AM, Andrew Peckover <apeckover@pgmusic.com> wrote:

Hi,

Does anyone know where I can find some good documentation on how to sign packages? I'm using PackageMaker 3.0.3.
