When you configure a proxy server on your Mac, applications will send their network traffic through the proxy server before going to their destination. This may be required by your employer to bypass a firewall, or you may want to use a proxy to bypass geoblocking and access websites that aren’t available in your country.
How to setup a proxy on Mac OS
1. Go to Apple menu -> System Preferences
If you want to configure the proxies used while connected to Wi-Fi networks, select “Wi-Fi”. If you want to configure the proxies used while connected to wired networks, click “Ethernet”.
2. Click the “Advanced” button
3. Select the “Proxies” tab.
4. To manually configure a proxy, you’ll need to enable one or more of the “Web Proxy (HTTP)”, “Secure Web Proxy (HTTPS)”, “FTP Proxy”, “SOCKS Proxy”, “Streaming Proxy (RTSP)”, and “Gopher Proxy” checkboxes. Enter the address and port number of the proxy for each option you enable. If you were provided with a username and password for the proxy server, enable the “Proxy server requires password” option and enter the username and password. If you don’t want to manually configure a proxy, ensure all these boxes are unchecked.
