Critical Code in Millions of Macs Isn't Getting Apple's Updates

"Overall, 4.2 percent of the Macs they tested had the wrong EFI version for their operating system version, suggesting they had installed a software update that somehow failed to update their EFI. For some specific models, the results were far worse: For one desktop iMac, the late 2015 21.5 inch screen model, the researchers found failed EFI updates in 43% of machines. And three versions of the 2016 Macbook Pro had the wrong EFI version for their operating system version in 25% to 35% of cases, suggesting they too had serious EFI update failure rates."

Do you think these were cloned rather than updated using the installer?

How do you know your firmware is up to date? It appears it depends not only what computer you have but also what OS you have installed.

This is an old Apple source [support.apple.com] but gives some information. I'm sure there is someone here who is Much more knowledgeable who can give more insight.

For example:
I have a Mid-2012 MBP with the following.
Model Identifier: MacBookPro9,2
Boot ROM Version: MBP91.00D3.B22
SMC Version (system): 2.2f44

Edit: OS 10.11.6 El Cap

I tried running the updater to see if I was up to date, what I got: "The installer requires OS 10.9 to run". I'm on 10.13.

Hmmm. Here is mine:
Model Identifier: MacBookPro9,2
Boot ROM Version: MBP91.00D3.B0E (different from Riley's above)
SMC Version (system): 2.2f44

Mine currently is running a cloned version of High Sierra (cloned from a 2010 Mac Pro install onto a blank hd) because I couldn't get a direct install. I kept getting a firmware error while using the Apple installer.

I cloned the fresh Mac Pro install and then used Migration Assistant form the previous MBP Sierra.

Just throwing it out there. Not sure what the official version should be.

It must not be very important if there isn't an up-to-date cross reference on Apple's site.

Yeah, one thing Im not seeing in these articles is the dire need if you dont have the correct one.

Even the wrong one is still really secure?

snippit form the article: the researchers's analysis of the failed updates didn't go so far as to quantify how many of those glitches left computers vulnerable to specific attacks.

I've got the same as Riley's except I'm running Sierra.

Edit: same machine: mid-2012 MacBook Pro9,2

I wonder if many of those machines were deployed is JAMF or some other cloning of the OS. That would explain the wrong OS to firmware match because they aren't running the OS installers. Apple is at fault here. The firmware updates should be independent of the OS installs.
