How to Easily Change MAC Address on Mac

A MAC address or Media Access Control address is a unique identifier assigned to a machine’s network interface. On your Mac, this is the unique hardware identifier of the WiFi or Ethernet card inside. Each device has a unique MAC address because if multiple devices on the same network have the same MAC address, the network cannot distinguish the two devices which causes quite a bit of trouble.

Since the MAC address is permanent and hardware dependent, it is mostly used to prevent a particular device from accessing the network. For example, on your home WiFi, you can easily set your router to only allow a specific list of MAC addresses to connect, so even if someone knows your WiFi password but isn’t added to the list of accepted addresses, that person won’t be able to connect to your network. This is one of those situations where you will want to change your Mac’s MAC address. So if you’re trying to circumvent a router that’s blocking your Mac’s MAC address, Here is how to change MAC address on Mac:
