Error 12 on 16" MacBook Pro [i9, 5500M] + Razer Core X + RX580
@itsage Thank you for the information on what causes those scenarios. I also received that Error 173 error initially trying to install the official drivers but if you reboot with the eGPU connected and try again it then installed correctly (but still Error 12)
I did try hot plugging the eGPU after booting with automate-efi and the BCD drivers leaving all the devices enabled and was still stuck with Error 12. Trying to disable devices was the last thing I did as a last ditch effort and the last thing I could think of left to do.
When I created the automate-efi boot disk I did use the install script and chose "NVIDIA" as the instructions said to due to out of date AMD patches.
Edit: And yes I am still on .295
death to self
@haoshiro I tried automate-eGPU EFI boot loader to see whether the Intel UHD Graphics 630 iGPU in the 2019 16-in MacBook Pro is usable. Unfortunately it's the same situation as 2018 & 2019 15-in MacBook Pro. While it's possible to enable the Intel iGPU and force attach it to the internal display, you'd get white dots and eventual black display. We have to wait for @mat_hd's December release of the BCD drivers to use both RP eGPU and Radeon eGPU at the same time.
@Haoshiro I'm also looking for a solution to this. I also experience the *exact* same issues like you. Error 12 no matter what. I think I tried all the things you tried. Anyway, my MacBook is slightly different. 2,4 GHz, 64 GB, 5500M 8 GB. And I am using the Razer Core X with a Radeon Vega64. So I assume it does not affect only RX graphic cards.
Will try a few different windows versions now. Starting with 1809 and then the newest 1909. Will let you know if I figure something out.
Tested both the 1809 and 1909... still no luck... - I'm really wondering what causes the issue. Especially as itsage doesn't have any issues getting this setup running at all.
Anyone else made any progress here?
The one thing I kept missing was the tiny check box at the bottom of the DDU settings that says keep Windows from reinstalling drivers after uninstall. This was key and the only thing I had forgotten before.
Interesting. I also has checked the checkbox and still experiencing error 12. I gave up on that. I sold my Vega64 and will get a 2080 soon. Don't need the eGPU under macOS anyway.
This is the post I followed verbatim (from itsage). Make sure to have the Win 10 xxxx.30 installer.
I have the same issue - I just can't get a 5700XT working without error 12.
Followed the process that everyone else has suggested to the letter.
Not installed any additional tools (automate egpu) yet, ideally I want to avoid that.
