In Mac OS X, how can I find the MAC address of my Ethernet or wireless interface?
In Mac OS X, your MAC (Media Access Control) address is distinct from the IP address assigned to your Mac, and is defined by the hardware of each Ethernet or AirPort interface. The MAC address is sometimes also called the Ethernet Hardware Address (EHA).
To find your MAC address, from the Apple menu, select
Preferences... . From the
View menu in System
In the left column of the
Network preference window that opens, click the name of
your connection (e.g.,
Built-in Ethernet). Click the
Advanced... button, and in the sheet that drops down, click
The address is the string of letters and numbers next to "MAC
Address:", "Ethernet ID:", or "AirPort ID:".
