Hello, it's the same laptop
Lenovo ideapad 520 15ikb
Intel 8250U with UHD 620 Kaby lake R + nvidia mx 150

It's the same efi as last attached in thread well still cannot install except that i added patch as in image.

Upon bbooting, I get a black screen after macos logo. There is backlight, but no output
I hhave tried all flags like -igfxblr -igfxonln=0 igfxdvmr (something like that) and what all i could find in whatever green guide. Nothing works. Backlight is there but black screen. Need help.


IGNORE that ! on top it's just I opencore not updated in ocat nothing else. Just cuz I redownloaded itit to click a pic. Otherwise I'm using updated ocat only to edit all the files.

Here.
Note I have tried igfxblr, igfxonln=0, igfxmetal=1 ONLY as of now. No luck. Black screen after boot.
Without the patch (in DP), i get Display without acceleration (7mb). Processor is Kaby-Lake-R with UHD 620.
I have seen a very similar thread in ur website where the person couldnt resolve the issue and u recommended EDID (something like that) 😭. I really need grafix dude pls help.
FOr other person, he just bought a macbook (WTH 😭). Its the same Processor with same igpu 8350U+UHD620. Do u think it will ever work? 😭

There are no connectors defined so black screen after boot is expected.

See connector patching:

In addition, remove -igfxblr and add -igfxblt. You'll also need to remove

Also, why is the SIP modified and you have added amfi_get_out_of_my_way=0x1? Don't say you used OCLP.

Lastly, what macOS version you have installed?

Hahaha, I spoofed my Intel Wifi card as brcm that applied OCLP. Then disabled the fake entry and loaded Airportitlwm for Ventura. This worked like a charm and Intel wifi is working at full speed natively :)
(Saw this workaround at github)
