Why epic games doesn't support macOS?

I just wanted to play Stranded Deep using GEFORCE NOW but when I discovered it is not supported I got upset till I realize the game supports macOS that’s great but unfortunately for Mac users you only offer steam option which costs 20 dolar while in epic games I can literally buy for it for a dolar. I can’t pay 20x. I can’t play on EPIC games and I can’t play on Geforce NOW. I seen there is a post about it 4 years ago which is crazy amount of time to realize that your game doesn’t support Mac on epic. İ don’t think other than this is some kind of a choice If it is tell me so that I stop caring about the game.
