Vuze, especially on a Mac, is the devil's tool. I would be inclined to recommend either Transmission or qBitTorrent. You need to make sure the correct port forwarding rules are in place. By default, Transmission requires that both TCP and UDP port 51413 be forwarded through your router or VPN to your computer.

On Mac, the right click is a Crtl plus click.

Thank you for the suggestions and for the link to the Azureus Preferences/Options.  I've made the recommended changes to 1:1 ratio and unchecking the boxes referring to 0 peers.  In the past I have restarted Azureus/Vuze once a day, but often it seems to run well on its own.  Now I need to be patient and increase my share ratio.   Thanks again!
