Weird, no clue, it's a zip, maybe use 7-zip, I don't know. I can't remake 3.1 anymore. I found an article, maybe this helps, I've never used a mac, I only have a PC to test the game.
I've found a hack for me. I downloaded the Mac ver via PC, opened zip folder and unzipped only the Contents folder and transferred Contents folder onto a drive and then onto the Mac, Then I went into contents-MacOS and click exec HoloLewd_Manager and it ran.
Interesting, I think the compression of the file maybe made it mess up. After all, no one has spoken up about it and I can't test it. In the future, I'll try not to compress it, maybe
