4. View the MAC Address: Click the “Advanced” button at the bottom of the window. In the “Hardware” tab, you’ll find the MAC address listed under “Physical Address.”

Method 2: Using Terminal

For those who prefer the command line, Terminal offers a quick way to access your MAC address:
1. Open Terminal: Launch Terminal by searching for it in Spotlight.
2. Execute the Command: Type the following command and press Enter:
“`bash
ifconfig en0 | grep ether | awk ‘{print $2}’
“`
3. View the MAC Address: The output will display your MAC address.
