Hi Stephane, ... made with PackageMaker when signing it for Gatekeeper (so that required intermediate certificates get embedded). As I wrote in another thread (Signing of packages and installation failures) 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 Hi, Does anyone know where I can find some good documentation on how to sign packages? I'm using PackageMaker 3.0.3. _______________________________________________ Do not post admin requests to the list. They will be ignored.
