Yeah I really hate Windows (and Microsoft) and it annoys me as well when a game is exclusive to Windows for seemingly no reason other than that the developer didn't bother to port it to other OS's. I get why they do it (Windows has the biggest user base by far) but still annoying.
Most of my games were made entirely on a Macbook, which is why I almost always make sure I have a mac build.
(Also while writing this comment I noticed the screenshot I used in the background for this page has a tiny glimpse of the High Sierra wallpaper around the edge, somehow I never noticed that before lol)
