What is a MAC Address?
Media access control (MAC) is the physical number that comes with every Network Interface Card. Be it a computer, phone or WiFi router, every device that can connect to the internet comes with built-in address called as MAC. The MAC address consists of 12 alphanumeric values with six pairs of 2 values separated by the dash.
E.g. – 1A-2B-3C-4D-5E-6F.
MAC is used to identify the device connected and can be traced out with provided number. However, you can change the Mac address of your computer /mobile by changing some settings.
As MAC address is hard-coded with the device, we cannot directly replace it. Instead, we can spoof the MAC address so that it can hide the original id and shows the spoofed MAC address.
Why change the MAC address?
Well, you might get this question. There are many reasons to change the MAC address of a device.
1. One of the reasons is to access the restricted network. For example, if some wifi network is allowing the only specific number of the device by filtering MAC ids. You can spoof the MAC id with one of the allowed MAC address to access the network.
2. Another reason to change mac address is that if your wifi provider allows only a certain number of devices, and you need to access the internet on the additional device. In this case, you can change the MAC address of that device with one of the already allowed devices.
3. One more reason to change the MAC Address is Privacy. YOur Ethernet connection can easily know your MAC address and track you. By spoofing Mac id you can hide from the network.
4. Hackers can use your MAC address if your MAC id is public. To protect your data and protect yourself, you can change the MAC address in your device.

Stop after you get “interface does not exist” error.
Now, we should compare these MAC with the address from settings. Go to System Preferences –> Network –> Select active network –> Click on Advanced button.
On the Hardware tab, you can see the Mac address. Now compare this Mac address with terminal addresses and check what “en“ value is to use. in my case it is en1
