First release version of what was EFIcienC, to check EFI firmware, security settings, and security updates automatically.
So you downloaded and installed a ‘silent’ security update. But how do you get it to work on your Mac? Isn’t that automatic too?
SwiftUI, notarization, malware detection, and Time Machine for APFS: all look worryingly incomplete in Catalina. Are they a bit premature?
With recent privacy protection, notarization requirements, and extended checking of executable code, it’s getting more common for an app not to launch. What can you do when that happens?

First full release version, which conforms to macOS clearance convention, and lets you know which flags it has changed.
How this occurs, why, and what to do to manage the problem when it affects you. Complete with a visual summary and references.
