Configuring network settings on macOS is essential for ensuring your Apple devices connect to the internet and local networks efficiently. This article will guide you through the process of configuring network settings using both the graphical user interface (GUI) and the Terminal command line interface on macOS.

Examples:

1. Configuring Network Settings via System Preferences:

   • Open "System Preferences" from the Apple menu.
   • Click on "Network."
   • Choose the network interface you want to configure (e.g., Wi-Fi, Ethernet) from the list on the left.
   • Click on "Advanced" to access more settings.
   • Here, you can configure various settings such as TCP/IP, DNS, and Proxies.
   • After making changes, click "OK" and then "Apply" to save your settings.

2. Configuring Network Settings via Terminal:

   You can also configure network settings using the Terminal for more advanced control. Below are some commands you might find useful:

   • List all network interfaces:

     networksetup -listallnetworkservices

   • Set a static IP address for a network service:

     sudo networksetup -setmanual "Wi-Fi" 192.168.1.10 255.255.255.0 192.168.1.1

     Replace "Wi-Fi" with the name of your network service, and adjust the IP address, subnet mask, and router address as needed.

   • Set DNS servers for a network service:

     sudo networksetup -setdnsservers "Wi-Fi" 8.8.8.8 8.8.4.4

     Replace "Wi-Fi" with your network service name and the DNS server addresses with your preferred ones.

   • Enable or disable a network service:

     sudo networksetup -setnetworkserviceenabled "Wi-Fi" off
     sudo networksetup -setnetworkserviceenabled "Wi-Fi" on

     Use "off" to disable and "on" to enable the service.

3. Checking Current Network Configuration:

   To view the current network configuration, use the following command:

   ifconfig

   This command will display detailed information about all network interfaces.
