SilentKnight
SilentKnight is a macOS utility that checks Apple security systems and available updates so you can monitor key protections on your Mac.
What is SilentKnight?
SilentKnight is a native macOS utility for checking the status of Apple security systems and available security-related updates on a Mac. It helps users review items such as firmware and security components that are relevant to keeping macOS up to date. The app is aimed at Mac users who want a clearer view of update-related security information than they may get at a glance from standard system tools alone. Common uses include checking whether important security components are current, reviewing firmware status, and confirming that core protections have been updated. SilentKnight is published by Howard Oakley and is offered as a free Mac utility through The Eclectic Light Company.

Safety overview
Status: Mostly safe
SilentKnight is distributed by The Eclectic Light Company as a notarized macOS utility, which is consistent with its purpose as a system-checking app. Because it reads update and security status, you should expect it to inspect system information related to macOS security components. Download it only from the publisher’s site, and if you want extra assurance, confirm that the app is signed for Howard Oakley and that the bundle ID is co.eclecticlight.SilentKnight before opening it.
Recommendation: Keep SilentKnight if you use it to check macOS security systems or update status. If you no longer use it, removing the app should mainly affect your ability to run these checks from its interface, and macOS Software Update will remain the standard way to install updates.
