System firmware utility — reads and writes NVRAM variables and hardware settings

Manages system-level non-volatile RAM (NVRAM) variables that control firmware behavior and hardware configuration. Communicates directly with hardware and firmware interfaces to read and write persistent settings across reboots. Accesses 19 bundle identifiers and 24 file paths to coordinate with other system components. Implements 7 entitlements for privileged hardware and storage access, indicating operation at the firmware management level rather than user-space.AI
