[EFI Loader] Error 12 Fix in Boot Camp for Apple T2 Security Chip Macs (apple_set_os loader v0.5)
@laurence_vines Remove the Samsung T5 USB-C external drive from the equation until you can get the eGPU going in Boot Camp. You can partition the internal drive with 50GB to test Windows 10 1903 V1 ISO on it. Use the boot loader in OP if you encounter error 12.
@e-v-min Stay on Win10 1903 .30 to .295.
Just wanted to chime in real quick and say that I just purchased the Razer Core X Chroma and it works for me without the port swap dance and without modified EFI. Just have to hot plug and it works.
Previously I had the Sonnet eGFX Breakaway Box which required port swapping, apple_set_os loader, and some sacrificial blood. YMMV
Which Windows 10 build are you on?
Mine was working fine hot plugging on Win 10 1903 v1, but as soon as Windows did the security updates today, I couldn’t hot plug it again until I reverted back to a restore point that preceded the updates. Based on itsage’s comment, the updates must have taken me out of the Win 10 1903 v1 .30-.295 range.
Confirmed for my system, reverting back to Win10 1903 .30, worked fine for my system. I returned the Razer Core X and switched to the Razer Core X Chroma and it now it also works for me without the port swap. I also deleted the modified EFI with no issues. Just boot into windows, plug the Chroma in, and it works great.
