MacOS Security And Privacy Guide
This project is a security hardening guide and privacy configuration manual for macOS. It provides a comprehensive set of instructions for configuring system settings to improve privacy, reduce the attack surface, and implement a malware defense framework.
The guide covers technical methods for validating software notarization, verifying application sandboxing, and auditing system activity. It distinguishes itself by providing detailed workflows for restricting high-risk features and applying advanced security configurations to protect the operating system.
The documentation covers several key capability areas, including network privacy through encrypted DNS and packet filtering, data encryption for disks and backups, and identity protection via metadata removal and anonymized browsing. It also includes procedures for system auditing by monitoring process execution and network activity.
