Exactly...perusing the wikipedia page I see RDR2 is currently the most expensive game ever produced with a cost akin to Avengers: Infinity War (and probably Endgame as they were made at the same time). Rockstar knows it's market is PC gamers and consoles, and the Mac isn't even mentioned by the unpaid interns they have working there, because that would end the internship immediately.Yep, people forget that sometimes AAA games have budgets in the hundreds of millions. These are essentially blockbuster movies at this point. Voice actors, motion capture, SOME have very good and long stories like Final Fantasy 7 Remake ($200 million budget BTW). Why target something as small as macOS marketshare?
