Understanding an EFI Check Result

[Droid13]

For a 15” MacBook Pro (Late 2013) running Big Sur 11.6, when I run

“/usr/libexec/firmwarecheckers/eficheck/eficheck --integrity-check”

I get

“Primary allowlist version match not found for version”

When I run

“sudo /usr/libexec/firmwarecheckers/eficheck/eficheck --integrity-check”

I get

“Primary allowlist version match found. No changes detected in primary hashes.”

Does this mean my EFI integrity is intact, but it’s not “allowed”?

I updated to 11.6.1 this morning; running EFI check now results in the following output:

"Primary allowlist version match found. No changes detected in primary hashes."

Seems whatever the cause was has now been fixed. I do wonder if it was a similar issue to that which has affected newer machines upgrading MacOS.
