macOS is a UNIX, but it's not Linux. It doesn't use X11 or Wayland, any more than Android does. If you removed Quartz, there would be no GUI left. If that's what you want, then there is Darwin out there. https://github.com/apple/darwin-xnu https://github.com/apple/darwin-xnu There have been various efforts to make it run as a standalone OS with X11: • Pure Darwin: http://www.puredarwin.org/ http://www.puredarwin.org/ • Open Darwin: https://archiveos.org/opendarwin/ https://archiveos.org/opendarwin/ • Next BSD: https://github.com/NextBSD/NextBSD https://github.com/NextBSD/NextBSD But they aren't much use. If you just want tiling windows, then I use Rectangle: https://rectangleapp.com/ https://rectangleapp.com/ For me that replaced Spectacle when that was discontinued: https://www.spectacleapp.com/ https://www.spectacleapp.com/
