This guide explains how to change the MAC address in macOS, whether you’re using a Mac desktop or a MacBook. The MAC address is a unique identifier assigned to a device’s network card by its manufacturer.
Don’t confuse the MAC address with an IP address. While a MAC address is fixed and identifies the network chip in your computer, an IP address can change. The IP identifies a device within a specific network—either a private IP for home use or a public IP when connected to the internet.
In simple terms, the MAC address acts as your device’s ID, while the IP address is its gateway to the internet. Although MAC addresses are typically fixed, you can change them using specific methods. Here’s how to do it easily on a Mac.
How to Change the MAC Address in macOS

To change your computer’s MAC address, first disconnect it from the internet. Then, open the Terminal app on your Mac or MacBook, type the following command, and press Enter:
sudo ifconfig en0 ether $(openssl rand -hex 6 | sed 's/(..)/\1:/g; s/.$//')
Enter your administrator password when prompted. Once entered, your MAC address will change to a random one.
If you prefer to set a custom MAC address, use the following command instead, replacing [new address] with your desired MAC address. Make sure the new MAC address follows the format a1:b1:c1:d1:e1:f1.
