Enabling TB1/2 Support on 10.13.4?

I know it's probably too early to assess anything, but I figured it would be better than not talk about it.

So before High Sierra, eGPU was completely doable on TB1 and 2 using the scripts. Native support also worked just fine till 10.13.4. That being said, unless Apple is trying to make a bold point –as in, they want to claim TB1/2 should not work with eGPU– and try to actively prevent it, I see a possibility on re-enabling eGPU supports on TB1/2 computers.

I guess the question really boils down to, aside from Apple's official support, would it be possible to have eGPUs working again on older TB1/2 devices?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

I think a few people have looked into it, but haven't reported their findings yet (possibly they're still looking at what's changed in the final). I'll have a look into it too, but as I have an Nvidia card some drivers will be needed first. Not sure how far I'll get, I write graphics software, not kernel/driver type stuff. 

Another question I'd like to know the answer to: has anyone filed a bug report with sysdiagnose from a TB1/2 Mac? If so was there any response (other than "duplicate" at least)?

I don't believe there is any reliable method for making TB / TB2 Macs work on 10.13.4. The ability to do that was intentionally removed by Apple in this system version. So I'd say start with 10.13.3 and work your way down based on the techniques on this site which appear to be most stable based on comments.

Trying to force it on 10.13.4 is going to end in frustration IMO.

There wasn't a way to make it work on 10.3 either until somebody did some work and figured it out 😉 And we don't want to be stuck on 10.3 forever.

@psonice I have filed such bug reports and Apple has stated that only "TB3 macs are supported". It seems that the "unsupported configuration" mentioned initially is now truly - unsupported. I am looking into TB2 acceleration on the final build, just that I have less time on my hands, and no easy fix seems to be in sight as far as I've looked.

As a tech-hungry code-aphobe, getting by on the genius and generosity of others, I must share my operating procedure with you all: have faith! If you can code, code; if you can't code, solicit; if you can't solicit, search; and if searching and soliciting hasn't yielded results, wait. Then search again!

We will get past 10.13.4. Some of us hanging by others coat tails...
I say thank you, in advance!

You've been warned.

In the netkas forum, someone claims that he found the solution for enabling TB1/2 support on 10.13.4 but doesn't share any more information on what he did or where to look at. Just that some hacks have to be made or found and that all hysterical antics about Apple abandoning TB1/2 support continued...

I'm not that deep into macOS programming, but surely could lend a helping hand and try some things out if told where to start or what to look at...

If it turns out to be a reliable thing they're probably not telling anyone in order to figure out how to monetize the fix. If people will pay $50 for a TB3-TB2 adapter, they'll pay $50 for that fix as well probably. Especially trashcan owners. Of course, if Apple breaks the fix every new release, that "business model" won't work too well.

Rominator's solution is modded EFI firmware for the card. He has this solution for 6 months at least but says nothing about it except bragging on the forum.

Deja Vu - those guys did the same thing for NVIDIA support on High Sierra, but never shared details (unless that has changed now).
