So I put the entitlements you suggested in your other post, "TestFlight,` Provisioning Profiles, and the Mac App Store" in the tags. <?xml version="1.0" encoding="utf-8"?> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.files.user-selected.read-write</key> <true/> <key>com.apple.application-identifier</key><string>1234567890.MyApp</string> <key>com.apple.developer.team-identifier</key> <string>1234567890</string> </dict> </plist> I can now verity the .pkg file with Transporter and upload to App Store Connect but installing to the Applications folder does not work. I am making an Adobe AIR app so I may need to treat the UNIX executable included in the .app file as an embedded file.
