mottvlk Posted July 3, 2021 Share Posted July 3, 2021 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. HP Probook 650 G1, Core i5-4210M @2.60GHz/HM87, 8GB DDR3-1600, [email protected] EFI.zip Quote Link to comment Share on other sites More sharing options...
mottvlk Posted July 3, 2021 Author Share Posted July 3, 2021 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. EFI.zip Quote Link to comment Share on other sites More sharing options...
mottvlk Posted July 3, 2021 Author Share Posted July 3, 2021 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. EFI.zip Quote Link to comment Share on other sites More sharing options...
