I have successfully installed SierraAMD and it works fine.
But, trying to install HighSierraAMD-v3 I run into problems.
The installer loads the boot loader fine, but as soon as I choose HighSierra from the menu, I get a bunch of ++++++ and then some lines of commands (disappearing very fast to be able to see what they represent) and then a continuous stream of lines with the message "invalid kernel opcode (64 bit) and some hex numbers".
Then, I have to shutdown the machine to end it.
Any idea of what is going on?
