> 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.
