Find Your Mac Address
First, you'll need to find the Mac address that's associated with your network card installed in your Mac computer. Here's how you can do that:
- First, you'll want to disconnect your Mac from the Wi-Fi connection you're currently using. Then, do the next step.
- Hold down the 'Option' key on your Mac's keyboard. Then, while doing that, click your trackpad or mouse on the Wi-Fi or Internet connection icon in the upper right of your screen.
- Now the interface name and Mac address are displayed on your screen.
Seeing as most Mac addresses are permanent, you can trick or 'spoof' a Mac address that gets reported from an operating system. This could be helpful when connecting to a public Wi-Fi hotspot for privacy reasons.

To change your Mac address, you'll need to open the Terminal application from your dock (if that's where it lives) or by going through Mac's Finder. To open Terminal from Finder, click Go > Scroll down to Utilities, click it > then, open the Terminal application from the Utilities window.
Once you've opened the Terminal app, type this in terminal:

The x's represent a Mac address that you'll input, if you've already got one in mind for use.
If you'd prefer to use a random Mac address, then type the following in terminal:
