How to Change Your MAC Address on Any Device?

Changing your MAC address is a powerful technique used by network administrators, developers, and privacy-conscious users alike. Whether you're aiming to enhance privacy, bypass network restrictions, or test software, understanding how to change MAC address correctly across platforms like Windows, Linux, macOS, and Android is essential.

In this comprehensive guide from MonoVM, you’ll learn why you might want to spoof your MAC address, detailed step-by-step instructions on how to change MAC address Windows 10/11, Linux (Ubuntu/macchanger), macOS, and Android, plus troubleshooting tips, tools, and important legal considerations.

 

What is a MAC Address?

A MAC (Media Access Control) address is a unique identifier assigned to your network interface card (NIC). It is used at the data link layer of the OSI model to uniquely identify devices on a local network. MAC addresses are typically fixed by the manufacturer and look like this: 00:1A:2B:3C:4D:5E.

Why You Might Want to Change Your MAC Address

Changing your MAC address is sometimes called MAC address spoofing. Here are some common reasons:

Privacy & Tracking

Your MAC address can be used to track your device on networks, especially public Wi-Fi. Spoofing your MAC address helps protect your privacy by making your device appear as a different one, reducing tracking risks.

Bypassing MAC Filters

Some networks use MAC filtering to restrict access to authorized devices only. Changing your MAC address to one that’s allowed on the network can help you bypass such restrictions — useful in testing or legitimate troubleshooting.

Software Testing & Development

Developers and network admins often spoof MAC addresses to test network configurations, simulate different devices, or troubleshoot connectivity issues without needing additional hardware.

 

MAC Address Spoofing: Legal & Ethical Notes

Before proceeding, it’s critical to understand the legal and ethical considerations:

• In most countries, changing your MAC address for privacy or testing is legal.
• However, spoofing MAC addresses to gain unauthorized access or conduct malicious activities is illegal and unethical.
• Always use MAC spoofing responsibly and with permission on networks.
  
  

How to Change MAC Address on Windows

Windows users have two main options: using Device Manager (GUI) or using Command Prompt / PowerShell.

Using Device Manager (GUI)

1. Press Win + X and open Device Manager.
2. Expand Network adapters and right-click your active network device.
3. Select Properties, then go to the Advanced tab.
4. Select Network Address or Locally Administered Address from the list.
5. Choose Value, enter your new MAC address (12 hexadecimal digits without dashes), and click OK.
6. Restart the network adapter or reboot your PC for changes to take effect.

Note: For detailed instructions, refer to MonoVM’s Change MAC address through the registry tutorial.

 

Using Command Prompt / PowerShell

You can also change MAC address Windows 10/11 using the command line:

Check your current MAC using:

getmac /v /fo list

Disable the network interface:

Disable-NetAdapter -Name "Ethernet"

Change the MAC address using registry tweaks or third-party tools like TMAC.

Enable the network interface:

Enable-NetAdapter -Name "Ethernet"

This method is more advanced and often requires administrative privileges.

 

How to Change MAC Address Linux (Ubuntu/macchanger)

Linux provides flexible ways to change your MAC address, from temporary changes via command line to permanent changes using network manager configurations.

Using ifconfig / ip (Temporary Spoofing)

Bring down your network interface:

sudo ifconfig eth0 down

Change the MAC address:

sudo ifconfig eth0 hw ether 00:11:22:33:44:55

 Or using ip command:

sudo ip link set dev eth0 address 00:11:22:33:44:55

Bring the interface up:

sudo ifconfig eth0 up

This change lasts until reboot — it’s a temporary MAC address change.

 

Using macchanger (Recommended Tool)

macchanger is a popular utility to simplify MAC spoofing on Linux.

Install macchanger:

sudo apt install macchanger

Check current MAC:

macchanger -s eth0

Change MAC to a random value:

sudo macchanger -r eth0

Set a specific MAC address:

sudo macchanger -m 00:11:22:33:44:55 eth0

 

Making MAC Address Changes Permanent on Linux

To make your MAC address spoofing permanent, configure systemd or network manager:

For NetworkManager, add the following in your connection config:

[connection]

clone-mac-address=00:11:22:33:44:55

Alternatively, use /etc/network/interfaces or systemd-networkd files depending on your distro.

How to Change MAC Address on macOS?

Changing your MAC address on macOS can be done via Terminal commands, but keep in mind the System Integrity Protection (SIP) feature, which may restrict modifications to network interfaces on newer macOS versions.

Terminal Command to Change MAC Address on macOS

1.Open the Terminal app from Applications > Utilities.

Identify your network interface by running:

networksetup -listallhardwareports

2. Look for the interface name (usually en0 for Wi-Fi).

Temporarily change your MAC address with this command:

sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx

3. Replace xx:xx:xx:xx:xx:xx with your desired MAC address.

This change is temporary and will revert after a reboot.

 

SIP Considerations

If you want to make permanent MAC address changes, SIP must be disabled, which is generally not recommended due to security risks. Permanent spoofing on macOS is tricky and typically requires advanced configuration or third-party tools.

 

How to Change MAC Address on Android?

Changing MAC address on Android depends on whether your device is rooted or not.

Rooted Devices

With root access, you can spoof your MAC address using terminal commands or apps that require root:

Use terminal emulator apps and execute:

ip link set wlan0 address xx:xx:xx:xx:xx:xx

Apps like MAC Address Ghost or BusyBox offer GUI to spoof your MAC address.

Note: The interface may be different (wlan0 or eth0) depending on your device.

 

Non-root Alternatives

Without root, your options are limited due to Android’s security model:

• Some apps claim to spoof MAC but generally only work on certain devices or Android versions.
• Android 10+ introduced randomized MAC by default on Wi-Fi connections for privacy, but this doesn’t let you manually set a custom MAC.
• For more persistent spoofing, rooting is almost always required.

If you want to learn more about how to spoof MAC address Android properly, rooting your device is usually necessary.

 

Tools to Automate MAC Spoofing

Several tools exist to simplify the MAC address spoofing process across platforms, especially when you want GUI options or advanced functionality.

Tool Name	Platform	GUI/CLI	Features
Technitium MAC Address Changer	Windows	GUI	Easy GUI, supports permanent spoofing, popular
macchanger	Linux (Ubuntu)	CLI/GUI	CLI tool with GUI frontends, persistent changes
TMAC (Technitium MAC Address Changer)	Windows	GUI	GUI, multiple device support
BusyBox (MAC Spoofing)	Android (rooted)	CLI	Terminal command support on rooted devices

Why Use These Tools?

• They simplify the complex manual steps.
• Allow quick switching between MAC addresses.
• Provide options for temporary or permanent spoofing.
• Reduce risk of invalid MAC formats and errors.
  
  

Troubleshooting MAC Change Errors

Changing your MAC address may sometimes encounter issues. Here are common errors and fixes:

“Access Denied” or “Permission Denied” Errors

• On Windows, ensure you run Command Prompt or PowerShell as Administrator.
• On Linux/macOS, prefix commands with sudo to get root privileges.
• Android requires root access for permanent spoofing.
  
  

MAC Address Reverts After Reboot

• Many OSes reset MAC changes after reboot unless configured for persistence.
• On Linux, configure network manager or systemd to keep changes permanent.
• On Windows, use Device Manager or registry edits for persistent spoofing (Change MAC address through the registry).
• On macOS, SIP prevents permanent changes by default.
  
  

Invalid MAC Format Errors

• MAC addresses must be 12 hexadecimal digits, typically in pairs separated by colons or dashes.
• Avoid special characters or spaces.
• Example valid MAC: 00:11:22:33:44:55.

 

Final Thoughts

Understanding how to change MAC address is essential for network admins, developers, and privacy-conscious users who want to enhance their security or bypass network restrictions. Whether you want to change MAC address Windows 10/11 via Device Manager or PowerShell, spoof your MAC on Linux (Ubuntu/macchanger) using CLI tools, or figure out how to spoof MAC address Android on a rooted device, it’s crucial to follow platform-specific steps carefully.
