I’m trying to install Catalina on a new drive, and although see the Catalina installer I have installed on a drive partition when BootRunner kicks in, it asks me to restart and I do, but then I get no signal on my LG TV to see the screen. Do I need to create a profile or something for that installer drive?
Basically, I have the Catalina installer on an external drive partition. I want to boot from that and install Catalina to a drive in my Mac Pro. When I restart from the installer I lose signal to see the screen. I’m using HDMI and have tried swapping ports, also tried a other monitor… No joy!
My Mac Pro is a 5.1 2014 and I’m doing this to install on an unsupported Mac - https://www.youtube.com/watch?v=wxFzZWqoCng
I’m desperately trying tot get Catalina up and running to work. Help is much appreciated.
