If you want to change your MAC address in macOS Monterey or Big Sur, there are a number of traditional methods to spoof a MAC address, as well as an alternate method using the mac-spoof command-line tool. We’ll be covering mac-spoof now.

A MAC address, found on most computers, is used by networks to identify devices. Of course, not all networks will allow any MAC address onto their network. Additionally, some services use a MAC address to track a device. Keep this in mind if you plan on using the internet syncing feature with your various devices since manual syncing is limited to browsing history and bookmarks. And yes, MAC stands for Media Access Control (not Minneapolis Area Code) but is sometimes confused with Mac (which stands for Macintosh).

This is aimed at advanced users, as the majority of people don’t need to change their MAC address.

Using mac-spoof to Change a MAC Address in MacOS Monterey/Big Sur

Before you can get started with Homebrew, you need to install it on your Mac if you haven’t already. Here is the guide you can use (How to Install Homebrew on Mac – TechRechard) Assuming that’s done, just launch the Terminal app.

1. Installing mac-spoof on your Mac with HomeBrew.

brew install mac-spoof

2. Option-click on the wi-fi menu bar item in Mac OS to get the interface name (typically en0, sometimes en1).

3. Turning off or avoiding Wi-Fi can be a good way to help you focus for a while and get more done. To do this, go to the Wi-Fi network menu and temporarily turn it off.

4. To generate a new mac address, use the following command at the terminal:

sudo mac-spoof randomize en0

5. Return to the wi-fi menu and manually re-connect to Wi-Fi on the Mac. It should take effect immediately.

NOTE: When you change the MAC address it will remain that way until you revert back to the original one, or until you reboot your Mac.

Note that the process may vary from person to person. Some people report success by switching off wifi, changing the MAC address, and then rejoining it, while others see no change after they disable wi-fi first before making any adjustments on their laptop. In my testing, both of these mics ran on my laptop, and from what I can tell disabling Wi-Fi is more traditional.

Apple’s latest operating systems are changing the MAC addresses on iOS and iPadOS devices for iPhone and iPad. This means these devices now have a randomly generated private wi-fi address. Perhaps a similar privacy feature will arrive for the Mac eventually.

Whether or not this Mac spoofing approach is easier than using the bundled command-line tools on Mac OS is up to you and your particular use case.
