new Apple tools: eficheck (and nvm)

Apple has apparently created a tool for examining Apple Mac EFI firmware, called eficheck. As I understand things, it was released, then pulled due to some issues (bugs?), and is apparently now avabilable in latest macOS updates. Also, it sounds like there might be another tool for NVMe diagnostics.

usage: eficheck: [–save -b] [ –cleanup -b] [–generate-hashes [-b] [-p]] [–integrity-check [-h [-b]]] [–show-hashes [-h] | [-b]]
