o patch do primeiro post já tem isso

ativa o csm no bios

A csm já esta habilitada. Tentei e não consegui de jeito nenhum.  :( Vou tentar via opencore para ver se funciona.

Tested commands for HD4400. System loads, but the screen stays black. I have sound, so I deduce which desktop is active.

Do you know what I'm doing wrong?

But I saw some tutorials. They fake their graphics device id (4400 to4600). And using it full acceleration 

try connectors

@MaLd0n tenho um Acer Aspire 3 A315-54 que possui um i5 10210u + UHD620. Com a EFI para um modelo semelhante (Aspire 5 A515-54) que um amigo postou em outro post, estou com aceleração, audio, brilho, etc. Só me falta o HDMI. Trackpad não funciona e o teclado as vezes sim as vezes não, mas não importa agora. O que posso fazer pra fazer o HDMI funcionar? Quando insiro o conector, a tela do note apaga e acende, como se estivesse ligando a saida hdmi, mas sem imagem. O que posso fazer pra fazer o HDMI funcionar?

Já pesquisei, mas sem sucesso. Parece que o fato do meu processador ser Comet Lake mas com hd620 é um problema. O notebook está maravilhoso. Só falta isso. Por onde devo começar?
