Im having similar issue with my HS setup, dell latitute 3480, i5-7200U
Once the hdmi plugged in, the laptop display went blank, only could see the external tv
But, when i put my laptop to sleep & wake up again, both screen got display (hdmi still connected)
Even the hdmi could be plugged off & in (after sleep), the laptop display is fine
What could be the culprit?
Dell’s MacBook Pro IORegistry.zip
I'm rather new to Hackintosh and trying my first build with OpenCore on AMD, but I run into issues causing OpenCore to crash before even loading the macOS installer. As I'm not sure which one is causing the crash, I'm trying to resolve all of them and one of the error messages has to do with WhateverGreen, which I was able to see in this slow-mo loading video. Basically I'm getting an error that I'm running an unsupported processor, even though I think I was following this guide by the step.
What could be causing this and what do I need to do to resolve it?
-Perfect HackBook, HDMI Audio/Video, Bluetooth, AirPlay, Sleep, Lid Sleep, Auto Sleep, Audio, etc!
-Wifi card has been replaced with Dell DW1560!
-I'm using a S145-15IWL Model with Intel Core i5 8265u / Intel UHD Graphics 620
-Update bios/uefi to last version
Just paste EFI folder inside EFI partition
