Changing the Mac address on your device can be a useful skill to have, whether for privacy reasons or to troubleshoot network connectivity issues. In this tutorial, we will guide you through the steps of changing the Mac address on your Mac computer.

What is a Mac Address?

Before we dive into the process of changing the Mac address, let’s first understand what it actually is. The Media Access Control (MAC) address is a unique identifier assigned to network interfaces for communications over a network.

It consists of six pairs of alphanumeric characters (0-9 and A-F) separated by colons or hyphens. The Mac address is typically hardcoded into the hardware of your device and is used to identify it on a network.

Why Change Your Mac Address?

There are several reasons why you might want to change your Mac address. One common reason is to enhance privacy and security. By changing your Mac address, you can prevent websites or networks from tracking your device or collecting information about it.

Another reason to change your Mac address is to troubleshoot network connectivity issues. Some networks may restrict access based on the Mac addresses they recognize, so by changing your Mac address, you can bypass such restrictions.

Changing Your Mac Address

Now that we understand what a Mac address is and why you might want to change it, let’s get started with the actual process. Follow these steps:

Step 1: Open System Preferences

Firstly, open the “System Preferences” application on your Mac computer. You can find this in the Apple menu located at the top-left corner of your screen.

Step 2: Select Network

In the System Preferences window, click on “Network” under the Internet & Wireless section.

Step 3: Choose the Network Interface

In the Network window, select the network interface for which you want to change the Mac address. This could be Wi-Fi, Ethernet, or any other network interface listed on the left-hand side.

Step 4: Click on Advanced

Once you have selected the desired network interface, click on the “Advanced” button located at the bottom-right corner of the window.

Step 5: Navigate to Ethernet or Wi-Fi tab

In the Advanced window, navigate to either the Ethernet or Wi-Fi tab, depending on which network interface you selected earlier.

Step 6: Change Mac Address

Here comes the exciting part! In this tab, you should see a field labeled “Mac Address” or “Hardware Address.”

By default, it is set to “Automatically.” To change your Mac address, select “Manually” from the dropdown menu and enter your desired Mac address in the provided field. Make sure to follow the format of six pairs of alphanumeric characters separated by colons or hyphens.

Step 7: Apply Changes

After entering your desired Mac address, click on “OK” to apply the changes. You may need to enter your administrator password to confirm this action.

Verifying Your New Mac Address

To ensure that your Mac address has been successfully changed, you can follow these steps:

  • Step 1: Open Terminal.
  • Step 2: Type ifconfig and press Enter.
  • Step 3: Look for your network interface (e.g., en0 for Ethernet or en1 for Wi-Fi) and check the “ether” field. This field displays your current Mac address.

If the “ether” field shows your new Mac address, congratulations! You have successfully changed your Mac address.


Changing your Mac address can be a handy skill to have, whether for privacy or troubleshooting purposes. By following the steps outlined in this tutorial, you can easily change your Mac address on a Mac computer. Remember to use this knowledge responsibly and in compliance with applicable laws and regulations.

Now that you know how to change your Mac address, you have more control over your network connectivity and privacy. Happy browsing!
