## What it is
LinkLiar is a free, open-source macOS status menu application written in Swift for spoofing the MAC addresses of Wi-Fi and Ethernet interfaces. It runs a small daemon with administrator privileges to randomize or set link-layer addresses, protecting users from MAC-based tracking.

## Use cases
- randomize my mac's wifi mac address for privacy
- prevent tracking via mac address in public networks
- spoof ethernet mac address on macos with a gui
- change mac address without using terminal commands
- automatically re-randomize mac address on network changes

## When to choose
- you want a simple GUI instead of manual ifconfig commands
- you need MAC spoofing specifically on macOS
- you prefer open-source tools you can audit
- you want automatic randomization of interface addresses

## When to avoid
- you need MAC spoofing on Linux or Windows
- you use a 2018 MacBook where macOS prevents MAC changes
- you need a cross-platform or command-line-only solution
- you cannot grant administrator privileges to the app
