About:
Silnite is a utility designed to check for updates to EFI firmware and security data files on Apple silicon Macs. It helps users verify that their system's low-level firmware and security components are current, which is crucial for maintaining system integrity and security. This tool provides a simple way to monitor these critical, often overlooked, system components.
Key Features:
  • Checks for EFI firmware updates
  • Verifies security data file versions
  • Provides clear version comparison
  • Focuses on Apple silicon Mac security
Use Cases:
  • Verifying firmware is up-to-date after a macOS update
  • Monitoring security data file integrity
  • Pre-flight check before a system migration
Alternatives:
  • SilentKnight – Broader security tool that also checks LocalPolicy and other security files, while Silnite is more focused on EFI and security data updates.
  • System Information – Built-in macOS utility that shows firmware versions but does not actively check for available updates.
