What Is a MAC Address?

MAC stands for Media Access Control. A MAC address is a unique identifier assigned to a network interface controller (NIC) for communications on a physical network segment. Every WiFi card, Ethernet port, and Bluetooth module has its own MAC address, which means your Mac likely has several of them.

A MAC address usually appears as six groups of two hexadecimal digits, separated by colons or hyphens. An example looks like this:

AB:CD:EF:12:34:56

The first half of the address identifies the manufacturer, while the second half identifies the specific device. Because this address is burned into the hardware at the factory, it is sometimes called a physical address or hardware address.

It is important to note that modern versions of macOS use a feature called Private WiFi Address. This means your Mac may generate a different MAC address for each network you join to protect your privacy. We will cover how to check for this later in the article.

Why You Might Need Your WiFi MAC Address on Mac

There are many practical reasons to locate MAC address details on your Mac. Here are some of the most common scenarios:

  • Network access control: Some offices, universities, and apartment buildings require you to register your device’s MAC address before it can join the WiFi network.
  • MAC filtering: Home routers often allow you to create an allowlist or blocklist based on MAC addresses. To add your Mac, you need to know its WiFi MAC address.
  • Static IP assignment: Network administrators can assign a fixed IP address to a specific MAC address so your Mac always gets the same local IP.
  • Troubleshooting: If your Mac is having trouble connecting to a network, an administrator may ask for the MAC address to check logs or block/allow the device.
  • Parental controls and device management: Some router apps let you pause internet access for specific devices by selecting their MAC address from a list.

Regardless of your reason, the methods below will show you How to Find Wifi Mac Address on Mac? quickly and safely.

How to Find Wifi Mac Address on Mac? Using System Settings (macOS Ventura and Later)

Apple redesigned the settings interface starting with macOS Ventura. If you are using macOS Ventura, Sonoma, Sequoia, or a later release, follow these steps:

  1. Click the Apple menu in the top-left corner of your screen.
  2. Select System Settings from the dropdown menu.
  3. In the sidebar, click Network.
  4. Find Wi-Fi in the list of network interfaces and click the Details… button next to it.
  5. Look for the MAC Address field. It may be listed directly on this screen or under a Hardware tab, depending on your macOS version.
  6. Write down the address or copy it to your clipboard.

If you do not see a Details button, make sure Wi-Fi is turned on. Some versions of macOS hide hardware details when the wireless interface is powered off.

How to Find Wifi Mac Address on Mac? Using System Preferences (macOS Monterey and Earlier)

Older versions of macOS use System Preferences instead of System Settings. If you are on macOS Monterey, Big Sur, Catalina, Mojave, or an earlier release, use this method:

  1. Click the Apple menu and choose System Preferences.
  2. Click the Network icon.
  3. Select Wi-Fi from the list on the left.
  4. Click the Advanced… button in the bottom-right corner.
  5. Navigate to the Hardware tab.
  6. You will see the MAC Address displayed at the top of the window.
  7. Click OK to close the window when you are finished.

This method works reliably on most Intel-based Macs and older Apple Silicon machines running pre-Ventura operating systems.

How to Find Wifi Mac Address on Mac? Using Terminal

If you prefer the command line, Terminal offers a fast way to locate MAC address information without navigating through menus. Here is how to do it:

  1. Open Terminal. You can find it in Applications > Utilities, or by pressing Command + Space and typing “Terminal.”
  2. Type the following command and press Enter:
ifconfig en0 | grep ether
  1. Look at the output. You should see a line that starts with ether followed by your MAC address, such as:
ether ab:cd:ef:12:34:56

Important: en0 is not always the WiFi interface. On MacBooks without a built-in Ethernet port, en0 is usually WiFi. On iMacs, Mac minis, and Mac Studios with Ethernet, en0 might be the wired port and en1 might be WiFi.

To confirm which interface is which, run:

networksetup -listallhardwareports

Look for the entry that says Wi-Fi or AirPort, then note the Device name listed underneath it (for example, en1). Replace en0 in the first command with that device name if needed.

Another useful Terminal command is:

networksetup -getmacaddress en0

Again, substitute the correct interface identifier if en0 is not your WiFi port.

How to Find Wifi Mac Address on Mac? Using System Information

System Information (formerly System Profiler) provides a detailed hardware overview. This method is helpful if you want to verify the MAC address alongside other network details:

  1. Click the Apple menu and select About This Mac.
  2. Click More Info (or System Report, depending on your macOS version).
  3. In the sidebar, scroll down and select Network.
  4. In the main pane, look for Wi-Fi or AirPort.
  5. Find the MAC Address field listed under the WiFi interface.

Alternatively, hold the Option key while clicking the Apple menu, then choose System Information to open the app directly.

How to Find Wifi Mac Address on Mac? From Your Router Admin Panel

Sometimes the easiest way to find your Mac’s WiFi MAC address is to check the device list on your wireless router. This is especially useful if your Mac is already connected to the network:

  1. Open a web browser on a device connected to the same network.
  2. Enter your router’s gateway address in the address bar. Common addresses include 192.168.1.1, 192.168.0.1, or 10.0.0.1.
  3. Log in with your administrator username and password.
  4. Navigate to the Connected Devices, Device List, DHCP Clients, or LAN section.
  5. Find your Mac in the list. It may be identified by its computer name (for example, “John’s MacBook Pro”).
  6. Look at the MAC address column next to your Mac’s name.

Router interfaces vary by manufacturer, so the exact labels may differ. If you cannot log in, check the sticker on the bottom or back of your router for default credentials.

Ethernet MAC Address vs WiFi MAC Address

Your Mac has separate hardware addresses for each network interface. If your Mac has both an Ethernet port and WiFi, they will have different MAC addresses. Even two MacBooks of the same model will have unique WiFi MAC addresses.

When registering your device on a network, make sure you provide the WiFi MAC address if you plan to connect wirelessly. If you are plugging in an Ethernet cable, you need the Ethernet MAC address instead.

Feature Ethernet MAC Address WiFi MAC Address
Interface type Wired network port Wireless network card
Typical device name en0 or en2 (varies by model) en0 or en1 (varies by model)
Used for Cable internet connections Wireless internet connections
Uniqueness Unique to the Ethernet controller Unique to the WiFi card
Can be changed? Temporarily via Terminal (advanced) Temporarily via Terminal (advanced)

MAC Address vs IP Address: What Is the Difference?

People often confuse MAC addresses with IP addresses. Both identify devices on a network, but they operate at different levels and serve different purposes.

Feature MAC Address IP Address
Network layer Data Link Layer (Layer 2) Network Layer (Layer 3)
Permanence Hardware-based; generally permanent Logical; can change depending on network
Format Six pairs of hexadecimal digits Four sets of numbers (IPv4) or longer string (IPv6)
Example AB:CD:EF:12:34:56 192.168.1.15
Assigned by Device manufacturer Router or DHCP server
Primary use Local hardware identification Routing data across networks

In short, the MAC address identifies the physical network card, while the IP address identifies the device’s location on a specific network.

Tips and Best Practices for Managing MAC Addresses

Now that you know How to Find Wifi Mac Address on Mac?, here are some tips to keep in mind:

  • Understand Private WiFi Address: macOS may use a different MAC address for each WiFi network to improve privacy. If you register your MAC address with a network and then join a different network, the address may not match. You can disable Private WiFi Address in System Settings > Network > Wi-Fi > Details if a network requires a consistent identifier.
  • Do not share your MAC address publicly: While a MAC address alone is not enough to hack your computer, it is still a unique hardware identifier. Avoid posting it on public forums or social media.
  • Label your devices: If you manage multiple Macs, write down each WiFi MAC address and label the device. This makes router administration much easier.
  • MAC filtering is not foolproof: MAC addresses can be spoofed, so do not rely on MAC address filtering as your only security measure. Use strong WiFi passwords and WPA3 encryption where available.
  • Check after macOS updates: Major operating system updates sometimes reset network settings. If you use MAC filtering, verify that your Mac’s address has not changed after an update.

How to Change or Spoof a MAC Address on Mac (Advanced)

Some advanced users want to change their MAC address for privacy or network testing. macOS allows temporary MAC spoofing through Terminal, but the change will reset after a reboot.

Warning: Changing your MAC address can cause connectivity issues and may violate network policies. Proceed only if you understand the risks.

  1. Open Terminal.
  2. Disconnect from WiFi temporarily.
  3. Run the following command, replacing en0 with your actual WiFi interface and XX:XX:XX:XX:XX:XX with the desired MAC address:
sudo ifconfig en0 ether XX:XX:XX:XX:XX:XX
  1. Enter your administrator password when prompted.
  2. Reconnect to WiFi and verify the change with:
ifconfig en0 | grep ether

Because System Integrity Protection (SIP) is enabled on modern Macs, some interface changes may be restricted. If the command fails, you may need to disable SIP, which is not recommended for most users.

Troubleshooting Common Issues

If you cannot find your WiFi MAC address using the methods above, try these troubleshooting tips:

  • WiFi is turned off: Some macOS versions hide hardware details when the wireless interface is disabled. Turn WiFi on and try again.
  • Wrong interface identifier: If Terminal returns “interface not found,” you are likely using the wrong device name. Run networksetup -listallhardwareports to identify the correct port.
  • Private WiFi Address is active: Your Mac may show a different MAC address than expected because it is using a randomized address for that network.
  • No WiFi hardware detected: If System Information does not list a WiFi card, your Mac may have a hardware issue or the wireless module may be disabled.
  • macOS version differences: Apple occasionally moves settings between updates. If a menu item is missing, use the search field in System Settings or System Preferences to look for “Network” or “MAC.”

Frequently Asked Questions

What is the easiest way to find the WiFi MAC address on a Mac?

The easiest method is usually through System Settings or System Preferences under Network > Wi-Fi > Advanced > Hardware. It requires no command-line knowledge and works on most Macs.

Does every Mac have a unique WiFi MAC address?

Yes. Every WiFi network interface manufactured has a globally unique MAC address. No two Macs should share the same WiFi MAC address.

Can I find my MAC address without being connected to WiFi?

Yes. You can find the MAC address in System Settings, System Preferences, Terminal, or System Information even if you are not currently connected to a wireless network, as long as the WiFi hardware is present and enabled.

Why does my Mac show different MAC addresses on different networks?

This is likely due to the Private WiFi Address feature. macOS generates a unique MAC address for each network to prevent tracking. You can disable this feature in the WiFi details panel if a specific network requires a fixed address.

Is the MAC address the same as the serial number?

No. The serial number identifies your Mac as a product, while the MAC address identifies the specific network hardware. They are completely different identifiers.

Can I change my Mac’s WiFi MAC address permanently?

Not easily. MAC spoofing through Terminal is temporary and resets after a reboot. Permanent changes are not supported by macOS and may require disabling system protections, which is not recommended.

Do I need the MAC address to connect to home WiFi?

Usually no. Most home networks allow devices to connect using just a password. You only need the MAC address if the network uses MAC filtering or requires device registration.

Where is the MAC address listed in the router admin panel?

It is typically found under Connected Devices, DHCP Client List, or LAN settings. Look for your Mac’s device name and check the adjacent MAC address column.

Can I find the MAC address of a Mac that is not mine?

Only if you have physical or administrative access to that Mac. You cannot remotely retrieve another computer’s MAC address without permission or access to network logs.

Will resetting my Mac change the WiFi MAC address?

No. Erasing your Mac or reinstalling macOS does not change the hardware-based MAC address. However, Private WiFi Address settings may generate different addresses per network after setup.

Conclusion

Finding your Mac’s WiFi MAC address is a straightforward task once you know where to look. Whether you prefer the graphical interface of System Settings and System Preferences, the speed of Terminal, the detail of System Information, or the convenience of your router’s admin panel, you now have multiple reliable ways to locate MAC address information.

Remember to distinguish between your WiFi MAC address and your Ethernet MAC address, and be aware that Private WiFi Address may cause your Mac to show different identifiers on different networks. Use this information responsibly, avoid sharing your MAC address unnecessarily, and keep it handy for network registration, troubleshooting, and router administration.
