Can't make Tray Icon run on Mac OS Sierra

Carls-MacBook-Pro-2:MacOS carl$ which mono
/usr/local/bin/mono

Duplicati server will start with:
Carls-MacBook-Pro-2:MacOS carl$ /Applications/Duplicati.app/Contents/MacOS/duplicati-server &

Weirdly, the server will start without backgrounding the process, but then it will quit if the script’s process is killed. If I start it with “&” it runs even if I explicitly kill the script’s process.

From the web interface, I can build a backup, run it and it connects to Backblaze B2 and writes the backup successfully. Everything seems to run fine, just like it does on my Linux version.

For the life of me, I can’t get the tray icon to run. Which, considering there is apparently no way to stop the server, is kind of an issue.

Attempting to start the Tray Icon appears to run, but nothing happens:
Carls-MacBook-Pro-2:MacOS carl$ mono Duplicati\Duplicati.GUI.TrayIcon.exe" --no-hosted-server

And finally, simply trying to start Duplicati from its normal start script does nothing if I double-click in the GUI and returns this rather lengthy error (below) if I do it from the command line.

Does anybody know what’s going on?
