Integrity for Mac isn[SQ]t a single, well-defined program or feature like, say, "Microsoft Word." Instead, it refers to several Apple security mechanisms working together to protect macOS from unauthorized modifications and malware. These mechanisms fall under the umbrella of system integrity, and they operate at different levels.

Key aspects of Mac system integrity include :

*

System Integrity Protection (SIP):

This is arguably the most important component. SIP is a kernel-level security feature that protects critical system files and folders from unauthorized modification, even by root (administrator) accounts. This prevents malware from tampering with core system components, making it significantly harder for malicious software to take control of the system. It[SQ]s enabled by default in most macOS versions.

*

Gatekeeper:

This feature examines downloaded applications and prevents the execution of those considered potentially harmful. It checks the application[SQ]s digital signature to ensure it comes from a trusted developer and hasn[SQ]t been tampered with.

*

XProtect:

Apple[SQ]s built-in antimalware system that scans for known malware signatures. It[SQ]s a constantly updated database that helps prevent execution of already identified threats.

*

App Sandbox:

A technology that restricts the access of applications to sensitive system resources. This limits the damage a compromised or malicious application can do, even if it manages to bypass other security measures.

*

Notarization:

Apple requires developers to submit their applications for notarization before distributing them. This process verifies the application[SQ]s code and helps ensure it[SQ]s free from malware.


In summary, "Integrity for Mac" isn[SQ]t a product you can download or install, but rather a combination of built-in security features that work together to maintain the integrity and security of your macOS system. These safeguards are fundamental to the overall security of the operating system.
