I'm really sorry, but I can't do a Mac version at this time, as I don't have access to a Mac computer :(
But I have a solution! You can play it through ScummMV, since it now supports AGS games: https://www.scummvm.org/downloads/
I tried it on Windows and while it's not perfect (I only found some small graphical issues and slower performance in a scene), the game is completely playable! I have been able to finish it fine.
You just need to download ScummVM, unzip the game somewhere, and add its directory to the game list. The program will tell you it doesn't recognize the game (it's not in their database yet, or something like that), but it'll work nonetheless.
Let me know if that works! And of course, I can give you a refund as well. The game is free anyway!
