We did rebuild the game and reuploaded it. You may try to download it again and see if it works.
Nope, still didn't work, and just a quick question, when unzipped, the game should be 7.9 GB, right? I think there is a fix where the Mac user disables all firewalls/safety features on the Mac, but that's just very unsafe and not smart. Aside from that, same issue as before:
The application “Prologue Build (Mac)” can’t be opened.
