I tried using the instructions for building the installer with ANT and used AIR 4.0. With that version of AIR, it fails on OS 10.13.
When I ended up building with AIR 27 it works on 10.13, which according to the AIR 27 release notes[1] states "With AIR SDK 27, all AIR applications built for macOS will automatically have the NSAllowsArbitraryLoads key set as true in their info.plist file" Do you think the README should be updated with that information?
