🔒 What is SIP

System Integrity Protection (SIP) is a security feature introduced by Apple in macOS El Capitan (2015). Its purpose is to prevent unauthorized access or modification of critical system files, even by apps or users with root (admin) privileges.

🔐 What Does SIP Protect?

SIP restricts access to key system folders and files, including:

/System
/usr (except /usr/local)
/bin, /sbin
System apps like Safari

⚠️ What Happens if You Disable SIP?
✅ Advantages of Disabling SIP:

Allows certain apps or tools that require deep system access, such as:
- System tweaking software
- Apps that modify Finder or the Dock
- Some advanced developer tools

❌ Disadvantages of Disabling SIP:

Increased risk of malware and attacks
System files can be accidentally deleted or altered
macOS updates may cause instability
Not recommended for general users or work devices in production environments

🔍 How to Check SIP Status

Open Terminal and type:

csrutil status

If it returns System Integrity Protection status: enabled, then SIP is currently active.
