Lenovo Ideacentre 520-24ICB OpenCore Installation Problem


Recommended Posts

Hello, I installed Catalina on my AiO device with Clover and iGPU Radeon 530 active, but I could not switch to OpenCore system properly. Help is required in this regard. Icon is activated with ALC 274 layout ID: 21. But I can't get any sound at all. I don't want poor quality sound with VoooDHA. Big Sur would be healthier with OpenCore. I am adding the system log.


This guide is really nice, but I made it according to this guide. But I can't get past the black screen
