Mac App Locker

Mac App Locker is a native macOS application built with SwiftUI that provides application-level security by allowing users to lock specific apps with authentication. It features biometric authentication via Touch ID/Face ID, ensuring quick yet secure access to protected applications.

The app includes a comprehensive dashboard for managing locked applications, real-time app monitoring, and seamless integration with macOS window management. It operates as a menu bar utility with smart dock icon visibility that adapts based on window state and user preferences.

Developed with modern Swift architecture, Mac App Locker utilizes dependency injection for modularity, Combine framework for reactive state management, and native macOS APIs for app monitoring. The application enforces single-instance behavior at the system level and features robust window lifecycle management to ensure reliability and optimal UX.
