So, that's it. I've been working hard to fix the MacOS X version, to no avail. The steam staff have been kind enough to provide me some info to point me in the right track with this issue, but there doesn't appear to be any source I can track.
I'm asking: How many of you are mainly MacOS users for gaming? How many of you wouldn't be able to play if the game is only out for Windows and Linux?
I don't discard publishing the MacOS version in the future if a fix is found, but most likely, the game will launch for the two working platforms during this week.
Keep in mind, I'm a lone developer that worked on this game on his spare time for more than two years, and I'm seeing the code that runs smoothly in the editor crush my hard work and dreams, and that I'm with you guys if you think it's unfair to promise a thing and then not be able to hold it 100%.
I'm sorry and listening to suggestions, too.
