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 and access websites that aren’t available in your country. RELATED: The proxy server you set here will be used by Apple Safari, Google Chrome, and other applications that respect your system proxy settings. Some applications, including Mozilla Firefox, can independent from your system settings. Open the System Preferences application by clicking on it in your Dock, or going to the Apple menu > System Preferences. Click the “Network” icon. Select the network connection you use in the list.
For example, 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”. Click the “Advanced” button at the bottom right corner of the Network window. Select the “Proxies” tab. You’ll need to configure a proxy by enabling one or more of the protocol checkboxes here. To have your Mac detect whether a proxy is necessary and automatically configure the proxy settings, enable the “Auto Proxy Discover” checkbox.
