@cavesdev For further support, please answer the following:
- What is the exact model of your PC (e.g. HP EliteDesk 800 G4 Mini)?
- What is your video port configuration (e.g. 3 x DP ports)?
- Are you using any video adapters (e.g. DP -> DVI)?
- Have you configured your BIOS according to the PDF instructions attached here?
- Have you tried creating a macOS installer using a different USB thumb drive?
- What type of device is the drive where you are trying to install macOS (SATA 2.5" SSD or M.2 NVMe SSD) and what is the exact model number of the drive?
EDIT:
@cavesdev Thanks for your feedback on the OC install instructions. I have modified Step 3
here. When I first started providing draft EFIs, the EFIs weren't complete (so users needed to install OC first and then copy the selected parts of my draft EFI). My current and future EFIs will be complete and can simply be copied to Volumes/EFI.
