Hi Stephane, It was not my development system. I tested it on both clean install of Mac OS X 10.8 GM and 10.7.4 Lion (also not a development system).

Or if it was your development system, then you may have installed the intermediate certificate yourself. Hi Stephane, ... made with PackageMaker when signing it for Gatekeeper (so that required intermediate certificates get embedded). I signed packages with PackageMaker and then tested them on ML with spctl tool. The packages were successfully accepted. How did spctl accept packages without intermediate certificates ? It is still not clear. Thanks, Alexander 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 wrote: Hi, packages?
