A MAC address is an identification code. It is used to define physical devices in a network so that the network knows exactly which devices it is in communication with. There are many practical reasons to have MAC addresses. It helps prevent criminals from imitating devices that they do not actually have, and are useful for creating a number of network filters for protection or organization.
Usually, a MAC address remains unchanged forever, defining a specific network card as long as it lasts (that's the kind of point). But this ID code can be changed and we will discuss how – and why – to do so.
Let's talk about counterfeiting
Changing your MAC address, especially when you do what is often called counterfeiting. The word "forgery" has a negative connotation ̵1; it makes it sound like you're trying to fool someone. However, there are many valuable reasons to change your MAC address. Many do it for privacy. Changing MAC addresses regularly makes it very difficult for networks to track your device and how to use it. If you use time-out Wi-Fi that only gives you, for example, one hour of free Wi-Fi access (some companies, such as airports, do this), you can continue to get free Wi-Fi by changing the address from time to time.
But there are also some disadvantages to counterfeiting. The great thing is that companies often have security filters in place that only allow certain employees' devices to access their networks. If you forge an address, the network will no longer recognize you. That's why it's important to record your original MAC address before changing it! This is also why counterfeiting a workstation is often a bad idea – save this trick for your personal computers without BYOD if possible.

This shows all connected devices you currently have on this network. Select the one you want to change, right-click it and select Properties . In the window that opens, go to the Advanced tab and click on the Property option that says Network Address or MAC Address or something similar. This will take up the address in the small box Value .

Changing MAC Address on MacOS
Checking Your MAC Address
There are some address changes designed for MacOS ( MacSpoofer is one of the most notable), but the process of resetting your address is so simple that you probably don't need one if you just want to change once. First you want to check and record your MAC number please. Do you see the Wi-Fi sign in the upper right corner of your MacOS? Hold down the Option and click the Wi-Fi button. The second line that appears in the drop-down menu should be your address – and it will say Address in gray letters so there is no confusion.
Open a terminal [19659019 To find the app Terminal go to Applications select Utilities and select Terminal . It's time to print a few commands!
Choose how to change your address
If you want to enter a new set of numbers – you may want an address that is easy to remember – then use the terminal and enter “Sudo ifconfig en0 eter aa: bb: cc: dd: ee: ff ”but replace the alphabet with the code you want. If that doesn't work, try using "en1" instead of "en0" in the command. Clicking on your WiFi as we did earlier also shows the right options for your machine in the first row with the title Interface Name .
If you want to set a completely random number instead, enter (or maybe just paste), “Openssl rand -hex 6 | sed's / ( ..) / 1: / g ; s / . $ // & # 39; | xargs sudo ifconfig en0 ether "and hit enter. Again, if this does not work, try replacing en0 with your specific interface name. It's usually better for privacy to use a random MAC address.
A couple notes
This is not always a pure process. Driver compatibility, synchronization problems, network settings and other problems can cause roadblocks. Sometimes you have to be patient or change to another device.
You should also restart your network after changing your MAC address to fully realize the effects. If you are unable to restart Wi-Fi yourself, then turn off Wi-Fi on your device and restart it for a similar type of reboot.
