Yet another revelation discovered as of this morning...
I found (by accident) cold booting into Ubuntu then warm to MacOS enables thunderbolt as well!! No need for Windows (to test I removed my windows hd). What's cool about Ubuntu is it was super easy to install and more importantly, I didn't have to load any drivers...everything just magically showed up!!
This finding provides three new possibilities:
1. You can alternatively dual boot with Ubuntu/MacOS and eliminate windows as well as all the malware, driver incompatibilities, bootcamp/EFI nonsense, etc. that are associated!
2. For those still stuck on "43", maybe (just maybe) it'll enable PCIe tunneling into MacOS? (I still think you need "23" else I would have noticed beforehand)
3. Again, maybe (just maybe) it'll inspire the right person to develop a .kext so we can run natively!!???
If any 43'ers would like to try option 2 and report back findings that would be awesome.
Hope this helps...

for sure! the more People that are successful, the more we can squeeze the life out of our beloved cMP's (and save $6k for the time being!
Ubuntu is the winner at 19 sec!
From "Option" boot menu to login screen:
**Win10= 55 sec
Catalina= 24 sec
Ubuntu= 19 sec
**I could probably shave off 20 sec from win10 boot time with fresh install
There's probably a way to set next boot in Ubuntu.
Maybe grub-reboot
Or Grub Customizer

Do you hook onto the blue or the green chip? Blue, no?

And that works persistently ?
Really helpful would be ?
1. If you could let us know, how you boot back in to MacOs.
2. Which Ubuntu and which version you used.
3. if you had to install TB3 Drivers or not, and if yes which one(s).
That would be really, really, really, really, helpful ?
Im curious too, and found some info.
Thunderbolt Ubuntu 19.04
How To Install "thunderbolt-tools" Package on Ubuntu
Thunderbolt 3 Software Connection Manager Support Coming In Linux 5.5 For Apple Hardware
PDF guide and patches for making Linux v5.3 kernel to work with Thunderbolt 3 add-in card.
Github/linux/drivers/thunderbolt/
Only thing is, with Linux, if you have to install, it can get tricky if you don't know.
At least it used to be the way some years ago.
Would be cool, but I guess, as TSIAlex stated many times, its not that easy.
Possibly this Link from above Thunderbolt 3 Software Connection Manager Support Coming In Linux 5.5 For Apple Hardware could help to find out more.
Same here.
There is, Refind, Gurb, flag the boot disk in the Urbuntu terminal.
I have no idea which one works.
Interesting will be if it is possible to automate the restart to MacOS in Ubuntu,
don't even need to see anything
That's why so many people had a problem !
Most likely I have a "23".
There was only some problem getting bootcamp to work.
Even though I installed in Legacy mode my 5.1 EFIi died. I have found out about several reasons that can happen, Installing: in UEFI mode, by USB Stick in Legacy mode, worn EFI Chip, failed Firmware updates. And I suspect, but do not know at all, if Windows has internet access.
Definitely better to use Ubuntu.
I would, unfortunately I don't have the knowledge.3. Again, maybe (just maybe) it'll inspire the right person to develop a .kext so we can run natively!!???

Regarding booting back into macOS: you may be interested in recent developments made with OpenCore, which bring a boot picker to standard graphics cards.

as long as OC is a craft project I'll wait and see
There is no simple way to set the state even if you could get the state. If you don't know anything about the hardware, then you would have to be able to record the entire set of steps (sequence of changes) from boot and then replay those steps after next boot.
For example, if state Z has everything working, you can't just set state Z. You will have to go throw all the steps A, B, C, D, etc. to get to Z.
The best course of action is to study the Thunderbolt code in edk2, DSDT code in ACPI of Mac and PC, and Linux drivers.
It is as much as a “craft project” as thunderbolt is for the cMP.

WARNING!
Using OpenCore without extensive knowledge of the configuration options
may lead to a bricked Mac.
Why not, but that warning ...
and it won't be automatic like I had it.
Perhaps that warning is too harsh. We had one report, but its veracity has been questioned. The OpenCore guide also mentions how the configuration it proposes is safe. Nevertheless, the cMP has a fragile BootROM, and it is important to keep this in mind for everything.
I must admit that didn't expect this type of disquietude from a thread that is on the bleeding edge of cMP updates...
No drivers req'd for Ubuntu. TB just magically shows up!
Great !
And which Ubuntu Distro and which version of that distro ?
Wow
