The quickest way to find your MacBook's WiFi MAC Address

Your MacBook's WiFi MAC address (Media Access Control address) is a unique identifier that your computer uses to connect to wireless networks. You can find it in System Settings without any tools or restarts. Open System Settings, go to WiFi, click Details next to your connected network, and look for the "MAC Address" field — it will be a string of six pairs of numbers and letters separated by colons, like a1:b2:c3:d4:e5:f6.

If you are not currently connected to WiFi, you can still see the address by going to System Settings > General > About, then clicking System Report, selecting Network in the left sidebar, and finding WiFi under the list. The MAC address appears in the right panel.

Key Takeaways

  • Your WiFi MAC address is visible in System Settings under WiFi Details on any connected network.
  • If you are not connected to WiFi, System Report in the About section shows the address without needing a connection.
  • The address is a string of six pairs of characters separated by colons, and it is unique to your MacBook's wireless hardware.
  • You may need this address to register your device on a network, troubleshoot connection problems, or set up MAC filtering on a router.

Finding the MAC address through System Settings (connected to WiFi)

This is the fastest method if your MacBook is already on a wireless network. Click the WiFi icon in the menu bar at the top right of your screen, then select "WiFi Settings" from the dropdown. This opens System Settings to the WiFi panel.

In the WiFi panel, you will see your currently connected network listed. Click the "Details" button next to it. A new window opens showing information about that network. Scroll down or look for the "MAC Address" field — this is your WiFi MAC address. Write it down or take a screenshot if you need it for later.

Finding the MAC address through System Report (any time)

This method works whether or not you are connected to WiFi. Click the Apple menu in the top left corner and select "About This Mac." In the window that opens, click the "System Report" button.

In System Report, select "Network" from the list on the left side. In the right panel, you will see a list of network interfaces. Find "WiFi" or "en0" in that list and click it. The MAC address appears in the details below, labeled as "MAC Address" or sometimes "Hardware Address."

Understanding what the MAC address looks like

A MAC address is always 48 bits long and is displayed as six pairs of hexadecimal digits (0–9 and A–F) separated by colons. Your MacBook's WiFi MAC address will look something like a4:5e:60:c2:8f:1b or 00:1a:2b:3c:4d:5e. Every MacBook has a different one, and it does not change unless you replace the WiFi hardware.

Do not confuse your WiFi MAC address with your Ethernet MAC address (if your MacBook has an Ethernet adapter) or your Bluetooth MAC address. Each one is different. If you need a specific address, make sure you are looking at the right interface in System Report.

Why you might need your WiFi MAC address

Network administrators sometimes use MAC addresses to control which devices can connect to a WiFi network — a practice called MAC filtering. You may need to provide your address to register your MacBook on a corporate or school network, or to add it to an approved device list.

Some routers also let you set up MAC-based access controls or parental controls that apply rules to specific devices. If you are troubleshooting a connection problem with your internet service provider or network support, they may ask for your MAC address to look up your device in their logs.

What to do if you cannot find the MAC address

If you do not see a MAC address in System Report under Network, your WiFi hardware may not be recognized by macOS. Restart your MacBook and try again. If the WiFi interface still does not appear, your WiFi card may need to be replaced or there may be a software issue.

If you are using an older MacBook and System Report looks different, the steps are the same — go to About This Mac, click System Report, and look for Network in the sidebar. The layout may vary slightly between macOS versions, but the MAC address is always listed in the Network section.

Frequently Asked Questions

Is my WiFi MAC address the same as my IP address?

No. Your MAC address is a hardware identifier that stays the same on your local network. Your IP address is assigned by your router or internet service provider and can change. You need the MAC address for device registration; you need the IP address to communicate across the internet.

Can I change my MacBook's WiFi MAC address?

macOS does not provide a built-in way to change your MAC address through System Settings. Some advanced users can spoof a MAC address using Terminal commands, but this is rarely necessary and can cause network problems if done incorrectly.

Do I need my WiFi MAC address to connect to a public network?

Most public WiFi networks do not require your MAC address. You only need it if the network uses MAC filtering to control which devices can connect, or if you are registering your device with a network administrator.

What if my MacBook shows multiple MAC addresses?

Your MacBook may have separate MAC addresses for WiFi, Ethernet, and Bluetooth. Each interface has its own address. If you need the WiFi address specifically, make sure you are looking at the WiFi or en0 entry in System Report, not Ethernet or Bluetooth.
