How to Change Your MAC Address on Any Device

Your MAC (Media Access Control) address is a unique identifier for your device on a network. While modern systems randomize MAC addresses for privacy, changing them manually can still be useful. Here’s how to do it on Windows, macOS, Android, iOS, and Chrome OS.

Windows

Windows 11 (Built-in Method)

1. Open Settings (Windows key → Search “Settings”).
2. Go to Network & Internet and select Wi-Fi or Ethernet.
3. Click your network and find Random hardware addresses.
4. Set it to On or Change Daily.

Manual Method (Older Windows Versions & Windows 11)

1. Open Control Panel (Windows key → Search “Control Panel”).
2. Search for Network Connections and select View network connections.
3. Double-click your active network adapter > Properties > Configure > Advanced.
4. Select Network Address, enter a 12-character MAC address (e.g., A1B2C3D4E5F6), then click OK.
5. Reboot your computer and verify using Command Prompt: Type ipconfig /all to check.

macOS

Using Terminal

1. Go to System Settings > Network and select Wi-Fi or Ethernet.
2. Find and note down your MAC address.
3. Open Terminal (Search “Terminal” in Launchpad).
4. Run: sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx (replace en0 with your adapter name).
5. Reconnect to Wi-Fi and check if the MAC address changed.

Using Homebrew (Easier Method)

1. Install Homebrew (if not already installed).
2. Open Terminal and run: brew install spoof-mac.
3. Randomize MAC address: sudo spoof-mac randomize en0.
4. Verify with ifconfig.

Android

MAC Address Randomization (Android 10+)

1. Open Settings > Wi-Fi.
2. Tap the connected network > Privacy.
3. Set Use randomized MAC to On.

For Android 9 or Older (Root Required)

You need root access to manually change the MAC address, which is risky and not recommended.

iOS

Private MAC Address (Default)

1. Open Settings > Wi-Fi.
2. Tap the “i” icon next to the network.
3. Enable Private Wi-Fi Address (this randomizes your MAC).

Chrome OS

Changing MAC Address (Requires Developer Mode)

Warning: Enabling Developer Mode will factory reset your Chromebook.

1. Enter Developer Mode (this will reset your device).
2. Press Ctrl + Alt + T to open Crosh (Chrome Shell).
3. Run the following commands:
   • Disconnect from the Internet: sudo ifconfig eth0 down
   • Change MAC: sudo ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
   • Reconnect: sudo ifconfig eth0 up
4. Reboot your Chromebook to revert changes.
