So I thought I had everything right until a message came up saying my card isn’t metal compatible and it wouldn’t let me continue. I had inserted the original ATI5870 in order to get the boot screen, but in doing so I get the non-metal compatible error. If I insert my rx580, I don’t get a boot screen. What options do I have??
Please help, mine always stuck on "the macos installation couldn't be completed" during black screen with Appls logo. Some people could get rid of it by select Mac HD for reboot, but mine didn't show up any bootable drive.
I only wish I could add more thumbs up than my one. Thanks for the video
