We actually exported a Mac version for the initial release a few months ago (Build#1), but it had problems and wouldn't work on most Macs due to plugin/scripting issues. No one on our team has a Mac machine, so we can't test or debug builds exported to it, which is why the game isn't available on it yet. We'll definitely look into the issue in the future - right now, though, we're mainly focused on generating new content for the game (maps, quests, lewds, etc.).
In the meantime, quite a few people had no problem running the game through Wine. You have to drag the game's main folder to the desktop, and then run the .exe using Wine 3.19 (development release). Some of the newer version might work, but that's the one I remember Mac users playing the game with. Could be worth a try if you don't want to wait for a dedicated Mac release!
