Introduction

For some tasks you have to know the hardware address (also called MAC address) of your Mac. These documents shows you one way how to find it.

The Short Answer:

Android

The menu screens for a specific Android phone may vary slightly in terminology but the instructions are the same:

• From your home screen navigate to your All apps / programs menu and Select Settings from the list:

Apple macOS

• From the Apple in the upper left hand corner choose System Preferences
• Click on the Network icon
• Select Thunderbolt Ethernet (or Ethernet) for Wired or Wi-Fi (or Airport) for Wireless.
• Click on the Advanced button
• Click on the Hardware tab
• Your MAC address will be at the top of this window.
  The MAC address is the 12 character address e.g. 00:11:22:AA:66:DD 

Windows 10

• Right click the Start icon
• Select Network Connections
• Right Click on the Ethernet Icon
• Select Status
• Click Details button
• The MAC address is given in the Physical Address line and is made up of 12 characters e.g. 00:11:22:AA:66:DD

iOS (Apple iPhone, iPad, iPod Touch)

• Touch the Settings app.
• Touch General.
• Touch About.
• Your MAC address is given in the Wi-Fi Address line and is made up of 12 characters e.g. 00:11:22:AA:66:DD

The Process

Go to the Apple-Menu, and select the menu item 'About This Mac'.





















In the 'About This Mac' window click on the "System Report..." button.



In the left pane of the System Report window click on the 'Network' entry (you might have to scroll down to see the 'Network' entry.


You now should see a list of your network interfaces in the upper right pane. Select the interface for which you want to know the MAC address.
In the lower right pane you should now see detailed information about the selected interface. In the example above I have selected the 'Airport' interface (WiFi).
Look for the text line starting with 'MAC Address:', the address has the form 'd4:3a:00:23:fe:7b'. Be careful not to confuse the MAC address of your Mac with the MAC address of the next router, listed under 'ARPResolvedHardwareAddress:'
Below is another example, this time for the Ethernet interface of the same machine (not connected when the System Information app was started):

Here the same interface, this time connected:
