I had to reinstall macOS from internet recovery because I was missing the wallet app for Apple Pay, weird I know. Anyways, because of that I can confirm there is something more than just a firmware update going on here. Whatever Apple did to get this throttling and heat under control is definitely macOS related. The version that will download and reinstall is the original shipping version, if you run benchmarks with that it’s right back to throttle land. That’s super unfortunate. The computer should be able to cool itself, OS independent. This is getting a bit outrageous. I have a few more days before my return window is up and I’m seriously considering doing that return.
We have been having this conversation in another thread:
OS Level Throttle Fix Is Evidence Apple May Not Be Done Resolving The Issue
This thread is actually a great compliment and this post answers the question we were ending up with.
@johnalan you appear to be off the hook.
@CrashTestWalrus would also be good to know the exact reported version in System Information.
From what I am gathering, the T2 is now the replacement for all that the SMC used to cover (power management, fan control, etc) and is a security guard for the EFI firmware. What we're observing is the interplay between the OS and the T2 but the T2 itself doesn't appear to have received an update. Perhaps thats what we're waiting for.

Totally agree. This is my current trust test. I equally ignore people who believe it to be DOOM and people who believe it be excusable. It’s neither, but whatever allowed it to happen must be corrected. It’s not acceptable.
Yeah hard to straddle the line. I both agree its a big lapse and have faith they will rectify to an appropriate level (more than they are now).
Its definitely on somebody's performance review.

Many thanks for the honest answer.
I’m going to wait for the 2019 version now .....
A little dramatic I think. Just wait for a hardware level resolution and get your machine.

Also everything SMC used to deal with.
I found some more references to the T2 being the full replacement to the SMC. It seems to be universally reported in Snell's writing and Cabel Sasser, Panic cofounder:
So a friend asked me what I thought about the issue returning after the shipping build of Mac OS was reinstalled and if this was a bad sign. I don't think its bad. I hypothesize that its Apple leveraging the properties of this new Bridge OS and how flexible it is to apply a short term fix like this from the OS side. Isn't what they are officially saying is that there are keys missing on the Mac OS side from the way these two pieces interface? I would suggest, again, that this is not the permanent fix and that Apple would want to resolve this "in hardware" or as close to "in hardware" as we get these days ie sufficiently so that Bridge OS retains the fix when the supplemented Mac OS version isnt present.
Bridge OS is an entirely new kind of software to be managing those aspects of operation but its higher order than anything the SMC ever operated on. At this point, it would seem a safe bet that the functions previously held by the SMC were effectively "ported" to Bridge OS and this is a glitch in the port.
Pretty clear. Its more or less what he said in that article.
