To set up proxy on your Mac OS, go to Settings >> click on ‘Advanced’ and then ‘Browser.Advanced’ >> in the System section click on ‘Open your computer's proxy settings’.
In the opened menu, choose the needed protocol, add your server’s IP and the port number. Additionally, turn on ‘Proxy server requires password’ and add your username and password as specified in your Gsocks account. Make sure to save the changes, and you can proceed with browsing via proxy.
