The results are quite intersting.

When run as you sugest I got :

Xpra shadow --bind-tcp= --no-daemon
2019-04-05 20:50:47,908 closing tcp socket
xpra initialization error:

line 93, in main
     return run_mode(script_file, err, options, args, mode, defaults)
line 421, in run_mode
     return run_server(error_cb, options, mode, script_file, args, 
line 617, in run_server
     return do_run_server(error_cb, opts, mode, xpra_file, extra_args, 
line 1054, in do_run_server
line 1730, in no_gtk
     assert gtk.ver is None

So I played around for a bit with options to work around that and could 
not make it go away so I just temporarily modified the 
putting a return in as below to see what would happen :

def no_gtk():
     gtk = sys.modules.get("gtk") or sys.modules.get("gi.repository.Gtk")

It now works when run from the command line :

macserver:tmp schodge$ PYTHONPATH=/Applications/Xpra.app/Contents Xpra 
shadow --bind-tcp= --no-daemon

The performance is not amazing but that could be to do with the old 
server I have running the firefox.

It also looks like the MAC version was built without server support:

Xpra start --bind-tcp= --no-daemon
xpra initialization error:
  invalid mode 'start'

So I'm not realy sure wheat the next step is.

I realy want to display back individual windows as opposed to shadowing 
the whole desktop. Was there a reason for the OSX build the start was 
not enabled or should I just build it myself on the Mac ?

Also my hack of putting the return in is hardly a long term solution :)

Any advice,
