[HELP] black screen on HP 470 G7 – Sequoia

[JUser50]

Thank you for your previous help!
However, I’m now facing another issue: I don’t get any display when graphics acceleration is enabled. If I disable graphics acceleration, the display works, but I won’t be able to fully use macOS under these conditions…

From what I’ve researched, even though the exact model of my integrated graphics card isn’t displayed, it seems to be an Intel UHD 620, which is theoretically compatible with macOS. Despite this, I can’t get a proper display when graphics acceleration is enabled.

Do you have any idea what I could do to fix this issue?

(I have not installed macOS because I have no display from the installation screen with graphics acceleration enabled)

Try using AAPL,ig-platform-id 08009B3E or 06009B3E

hi! sadly neither works :(

I tried others but nothing works, so maybe my iGPU is not compatible?

Apply these patches.

framebuffer-con0-enable (DATA) 01000000
framebuffer-con0-flags (DATA) C7010000

It still doesn't work :(
Maybe there is something in the config that is not compatible with my machine?
config.plist.txt

[lzhoang2801]

Try it config.plist.txt

It seems to be stuck here :v

Update : black screen now
It doesn't seem to be crashed because some keys on the keyboard react like the shift key. It's just that I have no display.

Still nothing conclusive :(
