[Help] HDMI not working on Hackintosh – macOS Sequoia (Latest Version) – Intel UHD 620 / Comet Lake Laptop

[rockie008]

Hi everyone,

I'm currently running the latest macOS Sequoia on my Acer TravelMate P214 (Intel 10th Gen / Comet Lake, Intel UHD Graphics 620). Everything works pretty well so far — internal display, sound, USB, etc.

However, HDMI output is not working at all. I’ve tried multiple framebuffer patches with WhateverGreen.kext and made sure that my AAPL,ig-platform-id is set to 0000923E, but still no luck.

I’ve attached my current config.plist to this post in case someone more experienced can help me spot the issue or suggest the correct framebuffer settings for external display support.

Thanks in advance for any help or hints!

Thanks for the info!

In my case, I'm pretty sure the system doesn't have an NVIDIA MX230/MX250 — under Windows, only the Intel UHD Graphics 620 is listed and used.
There's no sign of a dedicated NVIDIA GPU in Device Manager or BIOS, so I believe the HDMI should be connected to the iGPU.

Appreciate any further suggestions in case I'm missing something!

can you try to add "enable-hdmi20" key and value "01000000" in config plist
