Hi Temmie, I just download the Mac version and I cannot open it.
Here's what I see: (direct translation: The application "Game" cannot be opened)
I don't know if that's because of the system (mine is Catalina 10.15.5) or just didn't work out for MacOS, probably it's about the system. Say, I used to play VA-11 Hall-A on MacOS, but after upgrading the system, I cannot open it again. So maybe some one have older MacOS version could give it a try.
I'll try Windows version anyway once I arrived home.
