NIC is associated with a unique MAC (Media Access Control) address which includes Wi-Fi cards and Ethernet cards also. So, a MAC address is a 12-digit hex code having size 6 bytes and is used for uniquely identifying a host on the internet.
router which transmits it to the internet. At the hardware level, your network card keeps searching for the other MAC addresses for lining up on the same network. It knows where to drive the request in the MAC of your network interface. An example of how the MAC address looks like is 2F-6E-4D-3C-5A-1B.

4. You can also change the MAC address in the old traditional way. This involves running a command for changing the MAC address by turning the network interface down, and after the process is complete, again bringing the network interface back up.
The commands are
Note: Make sure you replace the term eth0 with your network interface name.
5. Once finished, make sure to restart your network interface and then you’re done.
Also, if you want the above MAC address to always take effect at the boot time then you will need to modify the configuration file under
/etc/network/interfaces.d/ or the
/etc/network/interfaces. If you don’t modify the files then your MAC address will be reset once you restart or turn off your system
#3 Change MAC Address in Mac OS X
You can view the MAC address of different network interfaces under System Preferences but you can’t change the MAC address using System preference and for that, you will need to use the Terminal.

Note: If it doesn’t match your Mac Address as you saw in System Preferences then proceed the same code while changing en0 to en1, en2, en3, and further until the Mac Address matches.
9. Also, you can generate a random MAC address, if you need one. For this, use the following code in Terminal:
10. Next, once you have generated the new Mac Address, change your Mac Address by using the below command:
