Did you update OpenCore and kexts before installing Monterey? Also, Intel Wifi has specific kexts for every macOS version, you should replace them with the right one.

Hello, your work seems great, but I have a problem, when I want to boot the installer from the usb, I choose an option after a few seconds in black it returns to the boot list, I would greatly appreciate your help.

Seems related to wrong EFI configuration. Have you turned off secure boot? Also, you can try boot from a different USB port.

Hi Everyone! I continue to update and make modifications on this EFI folder. Today two things remain not working:

1. Microphone (I know this will never work, since it's patched through Intel Smart Sound Technology, that is unsupported on macOS).
2. 4K 60Hz HDMI through USBC port using DP-Alt mode (available in this computer).

About the second issue, I'm using an Ivanky USBC to HDMI 2.0 cable (it's actually an active USBC > DP > HDMI cable), and a Samsung U28E590D monitor (UHD, 28").

The SMBIOS I'm using is: MacBook Pro 16.2

The framebuffer settings are this:

BTW: 4K 60Hz works fine on this computer using Windows (same port, same cable, same monitor).

Hope you can help me.

TIA.

also try:
MacBookPro16,1, or MacBookPro16,3, or MacBookPro16,4

make sure to reset nvram on each try

next time zip and upload your EFI

Thank you for your time!

I've tried the SMBIOS you suggested, but the result is the same.

Also, I've noticed that I got no image at all from USBC connector (not just 4K, FHD and HD don't seems to work either).

When I plug the cable, the screen from the laptop blinks -like trying to connect to the external monitor-, but the external monitor just shows no image.

From the settings panel I see the monitor or TV connected, also I can move the cursor to the external monitor.

In this reply I attach the EFI folder.

this should be "Data"

<key>enable-hdmi20</key>
                <string>01000000</string>

Thank you!

Fixed the enable-hdmi20 to data.

Added the patches:

• framebuffer-patch-enable, 01000000, data
• framebuffer-unifiedmem, 00000080, data

since I read in the guide you suggested me that they are necessary to drive a 4K 60Hz screen.

Also, added the following boot arguments:

• -cdfon
• -igfxmpc
• igfxonln=1

Now I get a blinking orange/gray screen on the external monitor (4K), and the settings panel shows correct information about resolution.

When I connect my TV (HD), the laptop screen changes its resolution and the computer hangs until the TV is disconnected. Then the trackpad remains unresponsive.

not sure, you forgot to upload your config.plist
