Normally, I would also also need to ask:
* does the command output show anything useful?
* does it show a connection attempt?
But.. see below.

I assume that you're using the dialog GUI in "ssh" mode?

Xpra "shadow" mode used to work quite well on MacOS.
It used to be possible to run this simple command from any remote host:
xpra shadow ssh://USER@MACOSHOST/
And have the MacOS desktop just show up in a window, but Apple has
changed something yet again and so this no longer works.

Note: to connect using "ssh" mode, you need to install the "PKG" images
so that the "xpra" command will be found by the ssh connection.

To make matters worse, it looks like some of the API calls we had been
using until now no longer do anything (tested on a 10.14.x system) so
the remote mouse clicks and keyboard events aren't emulated properly..

Let me take a look at this as soon as I can and I'll get back to you.

Cheers,
Antoine
