PanicLock: Instant Touch ID Disable and Screen Lock for macOS

PanicLock is a macOS utility designed to enhance security by allowing users to instantly disable Touch ID and lock their screens with a single click or by closing their laptop lid. This tool addresses a significant gap in macOS, where there is no built-in feature to quickly disable biometric authentication. In situations where privacy is crucial, such as encounters with law enforcement or border agents, PanicLock ensures that users can switch to password-only protection without disrupting their session.

## Key Features

- **One-click Panic Lock**: Users can instantly lock their screen and disable Touch ID by clicking the menu bar icon or using a customizable hotkey.

- **Lock on Close**: When enabled, closing the Mac's lid automatically locks the screen and disables Touch ID, requiring a password to unlock.

- **Auto-restore**: After unlocking with a password, the original Touch ID settings are restored.

- **Keyboard Shortcut**: A global hotkey can be configured for quick access.

- **Launch at Login**: PanicLock can be set to start automatically upon logging in.

## Security and Installation

PanicLock operates with minimal privileges, using a privileged helper to adjust Touch ID settings. It ensures security by running only three hardcoded commands and verifying the connecting app's credentials. The app is entirely offline, with no data collection, making it a secure choice for privacy-conscious users. Installation requires macOS 14.0 (Sonoma) or later and a Mac with Touch ID. The first launch involves a one-time setup requiring an admin password.

## Development and Contribution

PanicLock is open source, allowing users to audit the code and contribute to its development. The release process involves building, signing, notarizing, and packaging the app for distribution outside the App Store. Contributions are welcomed through issues or pull requests on the GitHub repository.
