try transferring your EFI from your USB to your Hard drive EFI partitionEverytime I try to use multibeast it fails to install anything, saying see log file. Why does it always fail? I don't seem to be able to find any log file either.
When I try the efi on the install usb to the hdd I get a no entry sign on bootIt won't boot when I do that. I found I had to add lily kext and whatever green into other folder to get it to boot. Is that correct though? As even though it boots I can't install any updates either. They end up hanging halfway through.
Yep already done that. When I try to install High seirra update, it gets a bit further but ends with a screen saying MacOs could not be installed on your computer.In Terminal :
Code:sudo spctl --master-disable
Often the result of an expired security certificate.An error occurred while loading the installer resources
