Heya :3 I wish I could help you, but unfortunately, Tyranobuilder games + macs just don't seem to get along very well at all :(
I don't know any actual statistics, but a lot of mac users seem to have this problem. It worked alright on my partner's old work macbook, but I have no idea if it's worked for anyone else on mac because I don't know enough people that use them to find out >.<
I did search online for help in the past + posted in the support forums for Tyrano on Steam. If you haven't already, you could try some of the suggestions on this page. There just doesn't seem to be any real solution to the issue though :( The English community manager for Tyranobuilder pretty much just stated that the devs say the problem is macs are awkward, and kinda just left it at that with no actual fix >.< Which is incredibly frustrating!
I'm hoping to be able to work with a new engine soon cos I'm getting pretty fed up with all the issues Tyrano has that don't seem to get fixed :(
I can't upload a browser version either because the game is too large to fit within itch.io's acceptable size guide for browser games.
I hope you can manage to find a fix somehow, and I'm really sorry that there's nothing I can do to help :( Thank you so much for your interest in the game + I hope you're managing to stay safe :3
