MacOS does support tiling. You can tile exactly one window across the entire screen by pressing the green button. If you want to tile more than one window, you can buy additional monitors.
Strange. Is this new because AFAIK Windows was copied from MacOS and it had tiling at least from 3.0 ? Also in X window managers tiling was an old concept.
You can tile two windows. :-)

But yeah, I use Recrangle for my macOS tiling. I use it all day, every day.
Would love something that worked more like Pop!_os’ tiling, or perhaps i3’s.
