Where to find your Mac address in System Settings

Your Mac address (also called a physical address or hardware address) is a unique identifier for your MacBook's network connection. You can find it in System Settings in under two minutes without any special tools.

Open System Settings by clicking the Apple menu in the top-left corner, then select System Settings. Click Network in the left sidebar. If you're connected to Wi-Fi, click Wi-Fi. If you're using a wired connection, click Ethernet. Look for the "Wi-Fi Address" or "Ethernet Address" field — that's your Mac address, shown as a series of letters and numbers separated by colons, like a4:5e:60:d1:2c:8f.

If you don't see the address field right away, scroll down in the Network settings window. Some MacBooks show it immediately; others require you to scroll past connection status information first.

Key Takeaways

  • Your Mac address appears in System Settings under Network, in either the Wi-Fi or Ethernet section depending on how you're connected.
  • The Mac address looks like six pairs of letters and numbers separated by colons, and it's unique to your MacBook's network hardware.
  • You need your Mac address when connecting to restricted Wi-Fi networks, setting up device management, or troubleshooting network problems.
  • Every network connection on your MacBook has its own Mac address — Wi-Fi and Ethernet are different, and Bluetooth has a separate one too.

Finding your Mac address from the Terminal

If you prefer using the command line, you can pull your Mac address from Terminal in one command. Open Terminal (search for it in Spotlight by pressing Command+Space, type Terminal, and press Enter). Paste this command and press Enter: ifconfig | grep ether

Terminal will show you the Mac address for each network connection on your MacBook. Look for the line that says "ether" followed by your Mac address. If you're connected to Wi-Fi, you'll see an entry for en0 or en1. If you're using Ethernet, you'll see a different entry. The Mac address is the same one you'd find in System Settings, just displayed differently.

This method is useful if you need to copy the address quickly or if you're troubleshooting and want to see all your network connections at once. Terminal shows the raw information without any of the System Settings interface.

Understanding which Mac address you actually need

Your MacBook has more than one Mac address. Your Wi-Fi connection has one, your Ethernet connection (if you use a wired adapter) has another, and your Bluetooth connection has a third. When someone asks for your Mac address, they almost always mean the one for the connection you're actually using right now.

If you're on Wi-Fi, give them your Wi-Fi Mac address. If you're plugged into Ethernet, give them your Ethernet address. If you're setting up a device that connects over Bluetooth, you'd use the Bluetooth Mac address instead. The easiest way to know which one to use is to ask the person or organization requesting it — they'll tell you which connection type they need.

When you look in System Settings, you only see the Mac address for the connection type you're currently viewing. If you need to find a Mac address for a connection you're not using right now, click that connection type in the Network sidebar first.

Why you might need your Mac address

Restricted Wi-Fi networks sometimes use Mac address filtering, which means they only let devices with approved Mac addresses connect. Universities, offices, and guest networks often work this way. When you connect to one of these networks for the first time, the network administrator asks for your Mac address so they can add it to the approved list.

Device management systems also use Mac addresses to track and manage company-owned MacBooks. If your workplace uses mobile device management (MDM) or similar software, they may ask for your Mac address during setup. Some home network routers let you set up Mac address filtering too, though this is less common now.

Mac addresses are also useful when troubleshooting network problems. If your MacBook isn't connecting properly, tech support might ask for your Mac address to check your device's connection history or to see if there's a known issue with your specific hardware.

Copying and sharing your Mac address safely

Once you've found your Mac address in System Settings, you can click on it to select it, then press Command+C to copy it. Paste it into an email or form using Command+V. Make sure you're copying the entire address — it should have six pairs of characters separated by colons.

Your Mac address is safe to share with network administrators, IT support, or anyone setting up a network you need to connect to. It's not a security risk the way a password would be. However, don't share it with people you don't trust, since someone with your Mac address could potentially spoof it (pretend to be your device) on a network they control.

If you're sending your Mac address to someone by email or message, double-check that you've copied the whole thing correctly. A single wrong character will prevent the network from recognizing your device. Some people take a screenshot of the Mac address field to avoid typing errors.

What to do if you can't find your Mac address

If System Settings isn't showing a Mac address for your connection, first check that you're looking at the right connection type. Click Wi-Fi in the left sidebar if you're on Wi-Fi, or Ethernet if you're using a wired connection. If the field is still blank, try disconnecting and reconnecting to the network — sometimes the address appears only after a fresh connection.

If you're using a USB network adapter or other external hardware, the Mac address might be on a sticker on the device itself. Check the bottom or back of the adapter for a label that shows the address. This is especially common with older USB Ethernet adapters.

Restart your MacBook if the Mac address still won't appear in System Settings. This usually fixes temporary glitches that prevent the system from displaying network information. After restart, go back to System Settings and check the Network section again.

Frequently Asked Questions

Can I change my Mac address?

You can spoof your Mac address temporarily using Terminal commands, but this is rarely necessary and resets when you restart. Most people never need to change it. If someone is asking you to change your Mac address, they probably mean something else — ask them to clarify what they're trying to fix.

Is my Mac address the same as my IP address?

No. Your Mac address is your hardware's physical identifier on a local network. Your IP address is a number assigned to your connection and can change. You need both to connect to most networks, but they serve different purposes and look completely different.

Will my Mac address work on a different network?

Yes. Your Mac address is tied to your MacBook's hardware, not to a specific network. You can take your MacBook anywhere and the Mac address stays the same. However, each network has its own rules about which Mac addresses it accepts.

Do I need my Mac address to connect to public Wi-Fi?

No. Public Wi-Fi networks like those at coffee shops or airports don't use Mac address filtering. You only need your Mac address if the network specifically asks for it during setup or if you're having connection problems that tech support wants to investigate.

What if I see multiple Mac addresses in Terminal?

That's normal. Each network connection on your MacBook has its own Mac address. You'll see one for Wi-Fi, one for Ethernet (if you have an adapter), one for Bluetooth, and possibly others for virtual connections. Use the one that matches the connection type you need.
