What problem does it solve?

Implementing robust, App Store-compliant security features for macOS apps requires navigating complex Apple security frameworks, avoiding common misconfigurations, and adhering to the latest platform requirements for macOS 26+. This Skill eliminates the guesswork by providing production-ready guidance for all core macOS security workflows.

Core Features & Use Cases

• Keychain & Secure Storage: Securely store credentials and sensitive data, with support for app group sharing between apps and privileged helper tools.
• Biometric & Authentication: Implement Touch ID, Apple Watch unlock, passkey, and Sign in with Apple flows with proper error handling and fallback logic.
• Cryptography & Secure Enclave: Use CryptoKit for symmetric/asymmetric encryption, post-quantum primitives, and SecureEnclave-backed key operations for hardware-level security.
• Compliance & Hardening: Configure Hardened Runtime entitlements and App Sandbox to meet Mac App Store notarization requirements.
• Use Case: For example, use this Skill to add Touch ID-gated keychain storage for user API tokens, or implement post-quantum encrypted data sync for a cross-platform productivity app.
