Happy you enjoyed ^^
But to answer this question, allthough there are about 60 renders I will remake after I finished v1.7 (These being in the start of the story), and include a "SFW" version (This I am still 50/50 on), in terms of porting it to Mac, this I will not do. Maybe if I could pay someone to do it for me, but personally doing it? No.
Ren'Py version I feel is out of the question, as Ren'py supports a 16:9 aspect ratio and Autumn Boulevard's renders are 66:59 ratio (Maybe there is a fix to this, maybe not). Further more, there are a lot of exploring and gameplay parts to Autumn Boulevard that Ren'Py does not support. Further more, this conversion is not a snap of the fingers thing. I would need to write the code and stuff. It would probably take months for me to do it in a satisfactory manner I am happy with. And those months, I would rather spend doing other stuff not related to Autumn Boulevard, as writing it is making me very exhausted.
