The command "csrutil enable" refers to a command used in macOS (starting from OS X 10.11 El Capitan) to enable System Integrity Protection (SIP).
System Integrity Protection is a security feature implemented in macOS to protect critical system files and directories from being modified, even by the root user or administrative users. It restricts certain actions that could potentially compromise the system's security and stability.
By running the "csrutil enable" command in the Terminal application on a Mac, you enable System Integrity Protection and ensure that the protected system files and directories remain secure. This command is typically used when you want to re-enable SIP after temporarily disabling it for specific system modifications or troubleshooting purposes. Enabling SIP is recommended for most users to maintain the security and integrity of their macOS systems.
