Guide: Change Mac Address in macOS: Tips and Tutorial
You may have heard the term “Mac address” mentioned in passing. But what is a Mac address? It is a media access control address, which means it uniquely identifies network interfaces dealing with a network segment. Mac addresses are assigned to the network interface controller by a manufacturer and are stored in the hardware. Yes, we know this sounds like a bunch of tech mumbo-jumbo if you’re not really tech-savvy, but that’s the best way to stay tech and try to get the point across. A Mac address is associated with the network adapter hardware on your computer. Okay, that’s easier to understand, right? Cool. Okay, so if you’re reading this here and you want to change your Mac address in MacOS, we have to assume you’re a bit of a tech-savvy person. So, we will keep telling you how to change your Mac address from MacOS.
Find your Mac address
First, you need to find the Mac address associated with your network card installed on your Mac computer. Here’s How to do that:
First of all, you want to disconnect your Mac from the Wi-Fi connection you are currently using. Then perform the next step. Hold down the “Option” key on your Mac’s keyboard. While doing that, click with your trackpad or mouse on the Wi-Fi or Internet connection icon at the top right of your screen. Now the interface name and Mac address will be displayed on your screen.
Since most Mac addresses are permanent, you can trick or “spoof” a Mac address reported by an operating system. This can be useful for privacy reasons when connecting to a public Wi-Fi hotspot.
Change your Mac address
To change your Mac address, you need to open the Terminal application from your dock (if that’s where it is located) or by going through Mac’s Finder. To open Terminal from Finder, click Go> Scroll down to Utilities, click on it> and then open the Terminal application from the Utilities window. After opening the Terminal app, type this in terminal: sudo ifconfig en0 xx: xx: xx: xx: xx: xx The x’s represent a Mac address you enter, if you already have one in mind. If you’d rather use any Mac address, type the following in terminal: openssl edge –hex6 | sed ‘s /(..)/ 1: / g; s /.$// ‘| xargs sudo ifconfig en0 ether When you restart your Mac computer, the Mac address will revert to the default address. So whenever you need or want to change your Mac address in MacOS, just type one of the above commands in the Terminal application and you’re good to go. You will also likely want to restart your Wi-Fi connection after changing your Mac address to avoid network problems. So now you know how to find out what your Mac address is, and how to change it from macOS – be it personal privacy issues, or just because you now have the information and the personal steps you need to do to do it.
