About:
Lockdown is a command-line utility that audits macOS security settings against established best practices. It identifies misconfigurations and provides one-click remediation to harden the system. This tool is essential for users and administrators aiming to quickly verify and improve their Mac's security posture.
Key Features:
  • Comprehensive security auditing of system configurations
  • One-click remediation for identified vulnerabilities
  • Clear, color-coded output for easy interpretation of results
  • Lightweight and does not require installation or background processes
Use Cases:
  • Performing a quick security health check on a new or existing Mac
  • Hardening a system for development or production environments
  • Verifying compliance with security best practices after system updates
Alternatives:
  • osx-collector – Focuses on forensic evidence collection rather than configuration auditing and remediation.
  • manual configuration – Significantly faster and less error-prone than manually checking dozens of system preferences via command line or GUI.
