Boot camp Error code 12 on base model 2019 13" MBP (2 TB3 ports)
I downgraded my Windows 10 build to 1803 since many people encountered the dreaded error code 12 after updating to 1903.
Tried to boot from apple_set_os.efi. The EFI boot itself works but upon logging in into Windows, error code 12 still appears on device manager.
Disabling FaceTime camera and several other PCIE devices to give enough free resources for the egpu to work.
Installed bootcamp drivers from bootcampdrivers.com (2020 Adrenalin Blue Edition)
Tried all these methods but none worked. I am still new to setting up eGPUs. Any help would be greatly appreciated.
This thread seems to be tracking the most recent attempts:
Some have had success with swapping the pci.sys file and others say the latest Windows Insider builds fix the problem.
