> i wonder why they haven't done the same on Windows

Probably because a lot of people feel like they need exclusive fullscreen for best performance and/or latency. But in reality borderless fullscreen is exactly the same when games use the DXGI flip model. It bypasses DWM (the compositor) to render directly to the display when only the game is visible and seamlessly allows you to switch to other windows. You can even disable Vsync and it will allow screen tearing when bypassing DWM.

I consider this the fault of macOS. The way macOS handles full screen makes it a nonstarter as a gaming platform even if it had a huge gaming library.

Still, I’ll admit that Minecraft full screen on Mac is even worse than almost all other games.

Does macOS even have exclusive fullscreen anymore? I haven’t looked into it, but my impression is that it fakes it with borderless windowed even when the app explicitly asks for it.
