However... When I boot from the USB installer & then start the "boot macOS install <myDrive>" step, it almost runs to completion. As part of this step, the update to Preboot happens at the end of this upgrade. The Preboot upgrade fails consistently.
I was trying to find out if the Preboot upgrade failure was normal on AMD. Or... have I screwed up the installation.
I understand the basic AMD installation & what's happening. I'm just not sure about Preboot & Recovery.
