How to Find the MAC Address on a Windows or Mac Computer
When registering a computer on the University's campus network service, you need to locate the computer's Media Access Control (MAC) Address. Also, sometimes when troubleshooting computer networking issues, you may need to locate the computer's (MAC) address.
This article describes how to locate the Media Access Control (MAC) Address on a Windows or Mac computer. Instructions differ slightly based on which version of Windows you are running.
Opening the Command Prompt
- Open the Start Menu by clicking the Start Button.
- Type 'cmd' in the Search box then click Enter.
- Go to your desktop.
- Open a Windows Explorer window by clicking on the Windows Explorer icon on the taskbar.
- Click on the small Folder icon in the Address bar, type cmd, then press Enter. A new Command Prompt window will be opened.
- Go to your desktop.
- In the search box, type cmd. Or, type/speak (using the microphone icon) "Launch Command Prompt" in Cortana's search field.
Once you've opened the Command Prompt
- At the Command Prompt, type 'getmac /v /fo list' then click Enter.
- Your MAC Address is listed under Physical Address. Note: In the screenshot above, you'll notice two MAC addresses. Next to Connection Name: you'll find the type of MAC address it is. Typically, it's the Ethernet MAC address next to Physical Address: you are looking for, especially when registering for the campus network. The wireless MAC address comes in handy when troubleshooting wireless networking or infected computer issues. The "Cisco AnyConnect" adapter is not a physical adapter, it's used for VPN client access.
