it doesn't work

take a look at this efi...

I think I patched the whatever green the right way, cause now laptop doesn't restarts, but still it doesn't recognize the second monitor

p.s. I tried angelts last efi folder and I have no wifi so lets try to fix my efi.

Hello again, I get rid of the rest audio kexts and I kept only the AppleALC, I copied the angelts audio settings too but it didn't worked.

As for the framebuffer patching I did what you told me and it still reboots.

Hello, I recently installed Big Sur on my hp probook 650 g1.

Everything works perfectly

But, unfortunately I have no sound

and when I connect the display port cable, laptop restarts.

I would appreciate it if someone could take a look on my efi file.

Thanks in advance.
