I would like to ask for advice.
I created a game in the .app format For the Mac App Store I have to convert it to PKG in order to use the Application Loader and send it for verification. I performed all signing procedures successfully with codesign -f -s "3rd Party Mac application installer".
Then I created the PKG file. Everything seems to have gone the right way, even the PKG installation check is correct. The problem occurs when once installed in / Application I want to test the opening. The game does not start, it closes immediately.
How can I do?
The strange thing that I noticed that the terminal had returned me "support macOS system: 10.9" How can I change the macOS support at least to 10.12?
