ALC892 Laptop HD4000

Hi Badaxe. It was a mistake. The option is "disable dGPU"

I started a new thread as you wished.

Framebuffer problem; the HD4000 0x03006601 framebuffer does not have a HDMI connector.
Two choices:
1. Easiest, unlikely to work: edit dsdt/AAPL,ig-platform-id:
find: 0x03, 0x00, 0x66, 0x01
replace: 0x01, 0x00, 0x66, 0x01
2. Will work, use 0x03, 0x00, 0x66, 0x01, HexEdit or other hex editor:
AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri binary
Find: 03 00 66 01
Find: 04 06 00 00 00 04 00 00 81 00 00 00
Replace: 04 06 00 00 00 08 00 00 06 00 00 00

Similar edit (different framebuffer, different connector), see [Easy Guide] ML: HDMI Audio/HD4000/7 Series MB - Page 3

Still no hdmi output after -

2. Will work, use 0x03, 0x00, 0x66, 0x01, HexEdit or other hex editor:
AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri binary
Find: 03 00 66 01
Find: 04 06 00 00 00 04 00 00 81 00 00 00
Replace: 04 06 00 00 00 08 00 00 06 00 00 00

Can you verify it applied correctly - AppleIntelFramebufferCapri.kext

Rebuild Kernel Cache? IOReg?

IOReg shows one display connected, LVDS. Framebuffer edit is correct. Plug in the HDMI device and restart. Reply with new IOReg.

Edit: dsdt/HDEF/hda-gfx injection missing.

All working fine now, forgot to update dsdt..

Thankyou Toleda
