On a Mac:

  1. Choose Apple menu > System Preferences, then click Network.
  2. Select the network service you use in the list—for example, Ethernet or Wi-Fi.
  3. Click Advanced, then click Proxies.
  4. If you configure your proxy server settings automatically, select Auto Proxy Discovery to automatically discover proxy servers, or select Automatic Proxy Configuration if you’re using a proxy auto-configuration (PAC) file. If you select Automatic Proxy Configuration, enter the address of the PAC file in the URL field. Check with your network administrator if you need more information.
  5. If you configure your proxy settings manually, do the following:
    • Select a proxy server, such as FTP Proxy, then type its address and port number in the fields on the right.
    • Select the Proxy server requires password checkbox if the proxy server is protected by a password. Enter your account name and password in the Username and Password fields.

This should allow the game to update as normal. If it doesn't, please contact us for further troubleshooting.
