Is this series likely to ever get a Mac version made?
Well, everything is done mostly by one person. I've got a lot of projects on my hands. Maybe in the future when the series is repackaged without the NSFW, I can think of taking on a Mac version while I am going through the game removing the NSFW content for the PG version.
But, that is so down in the list of priorities right now, I cannot give you anymore information than that. Sorry.
