I’m with the other poster, I don’t understand what you mean by multiple display support. I use my Mac Studio with a two monitor setup and it works beautifully. Even better, when I set my MacBook next to it, some kind of Apple magic happens in the background and I can move my mouse over to it like it’s a third display, letting me drag files between the two machines, control windows, use my keyboard, copy/paste, etc.

I use Rectangle for window management and have 3 monitors. I’m really not sure what you mean by the multiple display support. The window management is easy to rectify with Rectangle or Spectacle.

Not OP but Mac doesn't support daisy chaining via display port alt mode over usb-c. It's a little ridiculous cause a hackintosh does so we know that they can support it. I assume they don't because it drives sales of their absurdly priced monitors.

Windows (and to a lesser extent Gnome) have much better Window handling. Shortcut keys for tiling, snap to grid, snap to fill, window-walking (I don’t actually know what this feature is called but it’s when you cycle through window snaps and the window will “walk” across each position of each display in order).

Meanwhile macOS has none of these things and struggles to remember my display arrangement between restarts.

Sure I can download Rectangle/Spectacle/Amethyst and solve some of these problems (while giving screen observing permission to a third party) but it’s far from ideal and not at all what I used to have on Windows.
