Enter proxy server settings on Mac
If your computer is connected to a local network that’s protected from the internet by a firewall, you may need to specify proxy servers to access some internet sites. A proxy server is a computer on a local network that acts as an intermediary between a single computer user and the internet, so that the network can ensure security, administrative control, and caching service.
On your Mac, choose Apple menu
in the sidebar. (You may need to scroll down.)Click a network service, then click Details.
Click Proxies.
If you want to configure your proxy settings automatically, do one of the following:
To automatically discover proxy servers, turn on “Auto proxy discovery.”
If your network administrator provided you with the address of a proxy auto-configuration (PAC) file, turn on “Automatic proxy configuration,” then enter the address of the PAC file in the URL field.
If you want to configure your proxy settings manually, do the following for each proxy you want to set up:
Turn on a proxy, then enter its address and port number.
If needed, turn on “Proxy server requires password,” then enter your user name and password.
Click OK.
You can also choose to bypass proxy settings for specific computers on the internet (hosts) and segments of the internet (domains) by adding the address of the host or domain in the “Bypass proxy settings for these Hosts & Domains” field. This might be useful if you want to make sure you’re receiving information directly from the host or domain and not information that’s cached on the proxy server.
To bypass a single domain, enter the domain name—for example, apple.com.
To bypass all websites on a domain, use an asterisk before the domain name—for example, *apple.com.
To bypass a specific part of a domain, specify each part—for example, store.apple.com.
