## Prevent your Mac from leaking MACs

This is an intuitive macOS status menu application written in Swift to help you spoof the MAC addresses of your Wi-Fi and Ethernet interfaces. It is free open-source.

[➡️ How do I install this?](#installation)

If you star this project (by clicking on ✭ in the top-right corner), you help me to prioritize among my open-source projects.

![Screenshot](https://cdn.rawgit.com/halo/LinkLiar/master/docs/screenshot_3.0.1b.svg)

## Requirements

* macOS Sierra (10.12) or later (see [releases](https://github.com/halo/LinkLiar/releases) for older versions).

* Administrator privileges (you will be asked for your root password *once*).

## Installation

If you have [Homebrew](https://brew.sh), just run `brew install --cask linkliar`.

To install it manually, follow [these instructions](http://halo.github.io/LinkLiar/installation.html) in the documentation.

## Documentation

What you're looking at right now is the technical documentation.

The end-user documentation is located at [halo.github.io/LinkLiar](http://halo.github.io/LinkLiar).

There is also a source-code documentation in progress, see `bin/docs` for inspiration.

## Limitations/Caveats

* When your Wi-Fi (aka Airport) is turned off, you cannot change its MAC address. You need to turn it on first.

* If you change a MAC address while the interface is connected, you will briefly loose connection.

* If you rapidly close and open your MacBook, the MAC address may change while the Wi-Fi connection remains and you loose the connection (that is, if you have configured LinkLiar to re-randomize the MAC address).

* Whenever you successfully changed your MAC address, your `System Preferences` will still show you the original hardware MAC address.

  This is normal behavior and your actual network traffic uses the *new*, *changed* MAC address.

* 2018 MacBooks cannot change their MAC address, [because of a bug in macOS](https://github.com/feross/SpoofMAC/issues/87#issuecomment-485280175).

* As of macOS 12.3 (Monterey), the MAC address of an interface cannot be modified while connected to a network. That's why LinkLiar will disassociate from any connected network before modifying the MAC address.

## Troubleshooting

You can create this logfile and whenever it exists, all  LinkLiar components will write to it:

```bash

touch "/Library/Application Support/LinkLiar/linkliar.log"

```

Delete the log file again to silence logging.

Once LinkLiar is started and the menu is visible, you can hold the Option ⌥ key for advanced options. This is only intended for developers.

If you want a more colorful output, clone this git repository and run `bin/logs`.

That's what I use when I'm debugging.

This utility is also bundled in LinkLiar so you can run it with

```bash

# Run this in a Terminal for live debugging logs.

/Applications/LinkLiar.app/Contents/Resources/logs

```

## Development

![](./docs/modules_20211004c.svg)

#### HelpBook

To update the HelpBook (end-user documentation), change the *source files* in [LinkLiarHelp/en.lproj](https://github.com/halo/LinkLiar/tree/master/LinkLiarHelp/en.lproj) and *then* generate the output with `bin/docs`.

## Future work

* Add badge with test coverage to README
