- Mac: the proxy set in System Settings > Network > [your network service] > Details > Proxies.

- Server: the IP address or host name of the proxy server.
- Port: the port on the proxy server.
NOTE: For a SOCKS5 proxy, add socks5:// before the server address, for example socks5://proxy.example.com.

If your proxy server requires authentication, enter your credentials here.

FTP Proxy Server and Port (empty by default)
