Background for this topic.
macOS is the desktop operating system for Mac computers. Its security model combines signed-code checks and notarization through Gatekeeper, built-in malware detection, application sandboxing, System Integrity Protection, and privacy controls that restrict access to files, cameras, microphones, and other sensitive resources. FileVault can encrypt the startup volume, reducing exposure if a device is lost, although it does not protect data from an attacker using an unlocked account.
For security teams, macOS is an endpoint whose risk depends on timely operating-system and application updates, configuration, and user permissions. Vulnerabilities in macOS components, browsers, or widely deployed software can enable code execution or privilege escalation, while malicious or over-permissioned applications may bypass intended isolation through user-approved access. Organizations should track supported versions, enforce updates and disk encryption through device management, limit administrative access, and preserve relevant logs for investigation; security controls and available telemetry can vary by macOS release and Mac hardware.
