How to Find Your MAC Address

MAC = Media Access Control
The MAC address is in format xx:xx:xx:xx:xx

Apple: To find your MAC address, from the Apple menu, select System Preferences. From the View menu in System Preferences, select Network.

  • In Mac OS X 10.5 and later, in the left column of the Network preference window that opens, click the name of your connection (e.g., Wi-Fi, AirPort, Ethernet, Built-in Ethernet). Click the Advanced... button, and in the sheet that drops down, click the Hardware, Ethernet, or AirPort tab. The address is the string of letters and numbers next to "MAC Address:", "Ethernet ID:", or "AirPort ID:".
  • In Mac OS X 10.4, in the Network preference window that opens, make sure the pull-down menu next to "Show:" lists your connection (e.g., AirPort, Built-in Ethernet). Under the Ethernet or AirPort tab, the string of letters and numbers next to "Ethernet ID:" or "AirPort ID:" is your MAC address.


Windows: To find your MAC address go to Start. Type cmd in the Search bar. Type ipconfig -all . Scroll up to section, "Ethernet Adapter Local Area Connection." The MAC address is the string of letters and numbers next to Physical Address.

Linux:
/sbin/ifconfig -a | grep HWaddr

will return all the MAC addresses on the machine. The wired one will be called something like eth0, em1, p2p1, and so on. The wireless one should be called something like wlan0.
