Macshift

Overview

A command-line tool for managing MAC addresses of network adapters on Windows.

What is Macshift

Macshift helps you change the MAC addresses of your network adapters. It's especially useful when:

• Your device is having trouble connecting to networks (e.g., MAC address stuck on a switch/router)
• You want to enhance your privacy on public networks
• You need to bypass MAC address filtering
• You're testing network security configurations

Prerequisites

• Windows operating system
• Go 1.23 or higher
• Administrator privileges
• Network adapter that supports MAC address changes

Installation

Run the following command:

go install github.com/ezrantn/macshift@latest

Important: Always run macshift as Administrator. To do this:

1. Press Windows + X
2. Select "Terminal (Admin)"
3. Click "Yes" when prompted

Commands

List Network Adapters

Shows all available network adapters with their names and MAC addresses.

macshift list

Example Output

Available network adapters:

Name: Wi-Fi
Description: Killer(R) Wi-Fi 6 AX1650i Wireless Network Adapter
MAC: XX-XX-XX-XX-XX-XX

Name: Local Area Connection
Description: TAP-Windows Adapter V9
MAC: XX-XX-XX-XX-XX-XX

Change MAC Address

Generates and applies a random MAC address for the specified adapter.

macshift change -i "Wi-Fi"

Example Output

Generated random MAC address: 26:a5:a3:5d:b3:39
MAC address changed successfully to 26:a5:a3:5d:b3:39 on interface Wi-Fi

Restore Original MAC Address

Returns the adapter to its original MAC address.

macshift restore -i "Wi-Fi"

Example Output

Original MAC address restored successfully on interface Wi-Fi

Important Notes

1. Network Changes

   • Your network will disconnect briefly when changing MAC addresses
   • This is normal - just wait a moment
   • You may need to reconnect to Wi-Fi

2. Some network adapters don't support MAC address changes

Credits

This tool was inspired by a video by Dr. Jonas Birch where he demonstrates how to change and restore a network adapter's MAC address using the C programming language. The concept and the core approach were implemented in Go for simplicity and portability.
