Spoofing MAC address in MacOS Ventura on M1 chip
In macOS Ventura you can randomize MAC address involving the command line utility called spoof-mac. Here, we'll go through the HomeBrew-dependent mac-spoof technique.
MAC addresses are used by some services to filter who or what is allowed onto a particular network. Your computer's MAC address is unique and identifies it to connected networks. A MAC address is also used by some services to track computers and other devices. By the way, this article will discuss altering the MAC address on a Mac; however, MAC in this case refers for Media Access Control, not to be confused with Mac - which is short for Macintosh.
Note: There are other ways to spoof MAC address however this is the only one that worked for me in MacOS Ventura on M1 chip.
Using “spoof-mac” to randomize your MAC address in MacOS Ventura
Step 1: Install Command line tools in terminal
xcode-select --install
Step 2: install homebrew in terminal
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step 3: Disable analytics:
brew analytics off
You might already have Homebrew and Command line tools installed on your system. In this case just skip these 3 steps.
Now you can install packages through homebrew. You can read documentation with this command:
brew help
Installing packages is simple and you can run following syntax:
brew install [package name]
Step 4: Install spoof-mac with homebrew
brew install spoof-mac
Step 5: Interface name
Option-click on wifi icon in menu bar and get interface name (normally it is en0 or en1)
Step 6: Disconnect wi-fi
Disconnect wifi by toggling the wifi button so you’re no longer connected to wi-fi
Step 7: Run spoof-mac
in terminal run following command to generate random MAC address at your interface en0 (change en0 to en1 or other if applicable)
sudo spoof-mac randomize en0
Step 8: Turn on wi-fi
Toggle the button again and turn your wi-fi on. The MAC address will be changed untill you switch it back or reboot.
Restart spoof-mac
To restart spoof-mac after an upgrade or anytime you need you can run this command:
sudo brew services restart spoof-mac
Check your MAC address
If you want to check what is your MAC address you can run following commands:
spoof-mac list
You will see what is your spoofed mac address on the line where is en0 (or en1 if applicable)
Another option is to run following command:
ifconfig en0 | grep ether
It will show you MAC address on en0 (you can change en0 to en1 or other if applicable for you)
Double checking your MAC address:
Log into your wi-fi router and check connected devices and look for MAC address of your device. The MAC address should have same value like when running “ifconfig” command or "spoof-mac list" command.
Checking hardware MAC address and spoofed Mac address
Run following command where you can see hardware MAC address on port en0.
networksetup -listallhardwareports
You should be able to see difference in hardware mac address retrieved from the command above and spoofed mac address that you get from command “ifconfig” above.
