    Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

    Thank you very much @CaseySJ for the detailed instructions and EFI folder. I have created two previous Hackintoshes from older prebuilt business computers and decided I wanted something using current components. An observation: whilst I was waiting for the Graphics Card to arrive I used the...

    macOS 10.14.6 Supplemental Update 2

    Tried this fix but it did not work for me. So I dug a bit deeper and eventually got the Security Update to install. I deleted a folder from the drive called "macOS Install Data" and ran the updater again and it worked.
