LinkLiar

LinkLiar is a status‑menu utility for macOS written in Swift that lets users change the MAC (link‑layer) addresses of their Wi‑Fi and Ethernet interfaces through a graphical interface. By presenting the current address and allowing a new one to be entered, it replaces the manual command‑line approach (e.g., ifconfig en0 ether …) with a point‑and‑click workflow, helping users protect privacy by preventing nearby networks from tracking the device via its hardware identifier.

The application is open source and distributed for free, giving users full visibility into its implementation and the option to compile it themselves if they prefer not to grant administrator privileges. It is maintained intermittently by an independent developer, with updates driven by community interest and contributions on GitHub.

LinkLiar targets macOS users who need a simple, graphical method to spoof MAC addresses without resorting to terminal commands, positioning itself among other tools such as Airpass, WiFiSpoof, and command‑line utilities like SpoofMAC.
