"Your computer has detected a potential problem"

I got this alert this morning when I woke up my iMac (late 2015 model). I am running Catalina 10.15 (19A602)

The only readable part of the .dump file shows this

BIOS ID: IM171.88Z.F000.B00.1906171551

Model: IM171

EFI Version: 170.0.0.0.0

Built by: _atsserver@xapp157

Date: Mon Jun 17 15:51:50 2019

Revision: 170 (B&I)

ROM Version: F000_B00

Build Type: Official Build, RELEASE

Compiler: Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)

I ran "eficheck --integrity-check" manually and got this

EFI Version: IM171.88Z.F000.B00.1906171551 (Boot ROM Version: 170.0.0.0.0)

Matching allowlist not found in EFIAllowListShipping. Searching in EFIAllowListAll.

Fetching allowlist data update.

Waiting for allowlist data download to complete.

Allowlist data update failed with error = 108.

Primary allowlist version match not found for version IM171.88Z.F000.B00.1906171551 (Boot ROM Version: 170.0.0.0.0).

Any ideas?

Thanks

I'm on an 2015 27" iMac, and when I updated to Catalina, I started having this exact same issue. Once a week I get the "Your computer has detected a potential problem" message, and I'm shown a "eficheck.dump" file.

It seems my efi version was never updated. I reinstalled Catalina fresh again from recovery, and still get this message.

Help!

More Info:

I just check the content of /usr/libexec/firmwarecheckers/eficheck/EFIAllowListShipping.bundle and there is no IM171.88Z.F000.B00.1906171551 listed there. The only IM171.xxx listed is IM171.88Z.F000.B00.1909131902.0.ealf.

Searching on the web, "IM171.88Z.F000.B00.1906171551" is referenced by other users so it must have be a "correct" version at one point. The change date for "IM171.88Z.F000.B00.1909131902.0.ealf" is September 25th 2019 so this might be the latest version.

So was my firmware not updated correctly?

Thanks

More Info:

So it looks like my firmware version is good for Mojave and earlier but not for Catalina. So question: how do I fix this?
