[SOLVED] Intel HD 530 Mobile - HDMI\VGA not working - 10.14.1


Recommended Posts

Dear mates, yesterday I installed Mojave 10.14 on my system. The thing is that HDMI\VGA is not recognised, just when I start the system with cable plugged in. Was fine on Sierra 10.12.6. I saw some port patch, but they are for desktop version, not mobile. Also tried to replace AppleIntelSKLGraphicsFramebuffer.kext with same kext from Sierra> fixed the problem, but a new problem came up: After sleep PVAP - Hardware encoding broke result in application freezing, video freezing (Safari, yt, pictures, Final Cut, FaceTime, etc.) I can disable Hardware encoding, but then some features not working (Final cut, can't open pictures, thumbnails always loading, etc.).

Using platform-id: 0x191b0000 


Use this fix to get VGA/HDMI working: https://www.insanelymac.com/forum/topic/316573-sierra-applegraphicsdevicepolicy-clover-patch/

Last: No audio on HDMI

Fixed HDMI Audio by installing "FakePCIID_Intel_HDMI_Audio.kext"


System: Acer Aspire V5-591G-55TU

CPU: i5-6300HQ 2.3 GHz

RAM: 8 GB DDR4 (4+4)

GPU: Intel HD Graphics 530 + GTX 950M (disabled)

OS: Mojave 10.14.1


Updated to 10.14.1 and my outputs are gone again. > To solve this use the "AppleIntelSKLGraphicsFramebuffer.kext" from 10.14



Attaching the clover folder, IOReg

There's been very little to no support for VGA since Ivy Bridge generation.


You can look up the various patching guides posted in the Graphics R&D section for guidance on how to patch your particular SKL framebuffer layout. The principles remain the same since 4th gen Haswell graphics.

Thanks for help!

I found your guide, and I looked up my SKLFrameBuffer table, but that was good. Then I patched AppleGraphicsDevicePolicy with Clover and that is worked for me! HDMI & VGA & Internal are working now.

The last thing is HDMI audio, there is no audio on HDMI
