macOS High Sierra Supplemental Update!!!

I've received my 1080 Ti two days ago, installed into a Mantiz Venus, connected via TB3 to 2016 15" MBP with R460, connected the card to an external monitor, followed the guide provided by itsage (Boot Camp eGPU Setup Guide for Thunderbolt 3 MacBook Pro) fully on macos H.S. & win 10, iGPU is working as expected, disabled both PCIe 16x 1901 and PCIe 8x 1905, and using the right side TB3.
still the 1080 Ti shows error 12 in device manager whatever I do, I restarted win many times, and in every time I'm activating the apple_set_os.efi and boot windows from rEFInd, then disable / enable both PCIe again, but with no luck!!!

Next day and after being frustrated last night, I updated macos on the same exact setup with the new supplemental update (not sure if this is relative - testing by experts is required), and now with pessimistic trial, I decided to boot into windows (boot camp), I discovered that rEFInd is gone (may be due to a new firmware update in the supplemental update) so I decided to boot the usual way by holding the "option" key, without activating any apple_set.efi and without rEFInd at all.

And BOOOOOOOM... windows detected my EVGA GTX 1080 Ti without code 12 (attached screenshot)

And even without disabling any of the PCIe controllers (attached screenshot)

Then I performed some benchmarks (attached screenshots) including CUDA-Z with the expected performance.

I restarted widows again to make sure everything will run smoothly as per the first boot, and yes... everything works just fine without any error.

Moreover, I'm connecting many peripherals to the Mantiz Venus, and to the left side TB3 using Belkin TB3 Express Dock Station, even windows 10 (bootcamp) is on an external TB3 raid SSD by Glyph

However, on macOS H.S. the 1080 Ti is not detected at all till this moment...

This is just amazing...

I do appreciate all support and help I found in this magnificent forum, and would like to thank all eGPU gurus for their priceless help to average users like me through this forum.

Great news, congrats! I didn't need to do a thing to get my 1060 working either, looks like Apple is edging towards getting things working in Bootcamp...

Please note that I'm using 2016 MacBook Pro 15 Inch not the 2017 one, a huge difference is there...

Can anybody else verify that it has become easier to use egpus in High Sierra? Can 1070/1080s be attached without disabling controllers now?

If that is so, all we need is an boot with iGPU only option in bootcamp firmware.

I can't make it work, still have error 12 with MBP 2016 15inch RX455 and Mantiz venus + Aorus RX 580

I am reinstalling Mac and botcamp, I will test with Aorus RX 580 and Asus Strix 970 on botcamp.

For your information, I followed itsage guide completely but it did not work, then I re-enabled both 16x & 8x PCIe controllers and run the dedicated.bat from the graphics-switch, this is to reboot in macOS as advised by the guide, I did not uninstall intel HD Graphics drivers, and did not reinstall Radeon Pro 460 drivers, and I did not remove rEFInd or the apple_set file, they've just disappeared after the supplemental update.

I don't know, maybe if you followed the whole workflow it'll work for you.

That happened exactly the same for me. I had refind and I was booting on Bootcamp thru it and no problems to use the 1080ti. I used it on the Sierra as well. After I upgraded, I lost refind somehow, but now booting straight from apples boot selector also work on Windows. Not bad at all.

Hmm... this is interesting.

My situation is the opposite, last night I had it working with clover+modified DSDT. And now it suddenly stopped working as I mention in this thread here. Maybe I got the same update going without me noticing.

Thanks for this!

Before people start speculating,  I'm fairly sure that this update did nothing to improve eGPU compatibility either in bootcamp or in MacOS.

First check the change notes... a change such as this would of been mentioned.

Secondly check the other display adapter.  It's not an intel one, it's a Microsoft adapter (which happens to be the adapter used when a driver isn't installed).  The OP said he never removed the intel drivers, nor did he reinstall the AMD drivers. So the device that is active is the dGPU albeit without a driver.

The fact you can run without error 12 is consistent with nVidia hardware.

I had the same update, using the MacBook Pro 2016 RP460.  Checked and whilst I could login to windows.  My Vega 56 still had error 12.

I'm 90% sure that your success has nothing to do with Apple, perhaps nVidia tweaked some things on a driver level to get the internal display to work with dGPU's.

Additionally it's unlikely that refind is gone, rather the update sets the target startup disk to MacOS (which would appear to make it removed).  I suggest you check your boot partition to verify this.

Just bought a 1070... first boot I experienced error 12 (as I did with my 1050 and 1060) but was prompted to restart to finish setting up new hardware, after that it's all good... not getting much of a performance increase over my 160 though so may swap back (1060 6GB the sweet spot for U class CPU's?).
