I prepared an installer USB for High Sierra according the corp newt vanilla guide.

When installing, I first wiped the SSD (Which previously had El Capitan on it) and began the install process.

The installer begins and gives a progress bar, but always reboots at 2 minutes remaining. I first hoped this was to do with the natural multiple reboots that occur on real macs during such an install, and selected the usb install media from Clover on reboot. However this has not worked as, on rebooting to the USB, it is obviously starting again from scratch and once again reboots at 2 minutes remaining. I have to manually elect the installer utility so I'm pretty sure it's not picking up where it left off.

In desperation I hoped perhaps it really was completing and I just didn't get to see what happened after 2 minutes remaining before the reboot just starts. So I tried booting from the SSD. It booted successfully and began an installation process, however this process always stalls eventually with the message “MACOS COULD NOT BE INSTALLED ON YOUR COMPUTER”.

I looked up that message and found this (post)[https://hackintosher.com/guides/high-sierra-fix-macos-not-installed-computer/] which listed 5 possible fixes. Which I've worked through, to no success. This suggests to me that I was right to be worried the first time, it seems that the install process that occurs from the off the USB copies install media on to the SSD and as that process was incomplete, it can not complete this process from the SSD. Having tried all 5 of those steps, unfortunately, there are some introduced variables in that changes were made to the USB in line with the suggested solutions. I hope that those don't matter.

Anyway it looks like the problem is whatever is happening at that initial install off the usb progress bar that never makes it past 2 minutes. Anyone know what to do?
