How to Find Your MAC Address (Ethernet and Wi-Fi) on macOS

This article provides instructions on how to locate the Media Access Control (MAC) address for both your Ethernet (wired) and Wi-Fi (wireless) network adapters on macOS.

A MAC address, also known as a physical address, is a unique identifier assigned to your device's network adapter. It's often required for network troubleshooting, registering devices on their respective virtual networks, or setting up specific network configurations.

Method 1: Using System Settings/System Preferences (Recommended)

This is the most common and user-friendly method for finding your MAC address on macOS. The exact steps might vary slightly depending on your macOS version.

For macOS Ventura (13) and later:

1. Open System Settings:

   • Click on the Apple menu in the top-left corner of your screen.

   • Select System Settings.

2. Navigate to Network: In the System Settings sidebar, click on Network.

3. Select your Network Adapter:

   • For Wi-Fi: Click on Wi-Fi in the list of network services. Then, click the "Details..." button next to your connected Wi-Fi network or the "..." (more options) button if not connected.

   • For Ethernet: If you have an Ethernet adapter connected, click on Ethernet in the list of network services.

4. Find the MAC Address:

   • For Wi-Fi: In the "Details" window, select the Hardware tab. The MAC address will be listed as "MAC Address."

   • For Ethernet: In the Ethernet details, the MAC address will be listed as "MAC Address" under the Hardware section.

5. The MAC address is a 12-digit hexadecimal number, often displayed with colons (e.g., 00:1A:2B:3C:4D:5E).

For macOS Monterey (12) and earlier (using System Preferences):

1. Open System Preferences:

   • Click on the Apple menu in the top-left corner of your screen.

   • Select System Preferences.

2. Navigate to Network: Click on the Network icon.

3. Select your Network Adapter:

   • For Wi-Fi: Select Wi-Fi from the list of network services on the left.

   • For Ethernet: If you have an Ethernet adapter connected, select Ethernet from the list of network services.

4. Find the MAC Address:

   • For Wi-Fi: Click the "Advanced..." button in the bottom-right corner. Then, click on the "Hardware" tab. The MAC address will be listed as "MAC Address."

   • For Ethernet: Click the "Advanced..." button. Then, click on the "Hardware" tab. The MAC address will be listed as "MAC Address."
