> The closest set up for x11 would be to use x11 forwarding with xpra.

Older versions of macOS even had an X server distributed by Apple that you could install on your machine, and if memory serves right you were then easily able to forward X11 from a remote Linux host (or other operating systems running X11 applications) using ssh and have it render to your macOS desktop.

From a quick google search there is apparently still an Apple supported third-party open source project called XQuartz one can use.

X11 forwarding with ssh and XQuartz looks to work the same way that I remember using the Apple distributed X server in the past. Install the X server and then use the -X flag of ssh. Same way that you forward X11 between two Linux computers, or Sun workstations or whatever with an X11 desktop, over ssh.

This is Wayland. You could use xprs
