Lenovo-ThinkPad-T450s-Hackintosh-Big-Sur-OpenCore VS AppleALC

I am trying to install macOS Ventura on my thinkpad T450 using the latest OpenCore release. It seems that people have successfully installed it on the same hardware (https://github.com/CLAY-BIOS/Lenovo-ThinkPad-T450s-Hackintosh-OpenCore/issues/124).

I have used this guide https://github.com/CLAY-BIOS/Lenovo-ThinkPad-T450s-Hackintosh-OpenCore/blob/master/README-English.md and many others for each of the same problem. I have fully serviced hardwere. i think it might be a bios problem

There are two ALCPlugFixes that I found (racka98 and CLAY-BIOS and MultimediaLucario) . Both allowed me to follow the steps exactly as they were described in the readme, including the one where you drag the ALC3232.plist file and everything. I was able te execute well and never returned me any errors, neither of them.

The VGA, fingerprint and bluetooth (sometimes) dont work with this config but its been stable for the last month https://github.com/CLAY-BIOS/Lenovo-ThinkPad-T450s-Hackintosh-OpenCore

What files/config I am using: https://github.com/CLAY-BIOS/Lenovo-ThinkPad-T450s-Hackintosh-OpenCore - everything pretty much works if not counting bluetooth

Actually going to answer this myself: https://github.com/CLAY-BIOS/Lenovo-ThinkPad-T450s-Hackintosh-Big-Sur-OpenCore/tree/master/EFI/OC/ACPI

Conexant CX20724 ISST Audio - AppleALC, , layout ID 13

https://github.com/acidanthera/AppleALC/wiki/Supported-codecs set alcid accordingly

I don't. Have you looked at the AppleALC wiki to see which IDs that might need? https://github.com/acidanthera/AppleALC/wiki/Supported-codecs

I have a Comet Lake laptop (i7-10510U & UHD 620) with the ALC294 Audio Card. I've tried all of the layout ID's listed on https://github.com/acidanthera/AppleALC/wiki/Supported-codecs. But all of them sound the same. I'm also using macOS Monterey... Any fix?

Do not enter the digits of your audio codec as your alcid. For example: "alcid=298" (ALC298). Use appropriate alcids from the AppleALC wiki: https://github.com/acidanthera/AppleALC/wiki/Supported-codecs

CPU: Intel Core i5-10500H (Comet Lake) [CPU slightly undervolted within BIOS] GPU: Intel UHD 630 (+ NVIDIA GeForce 1650 with Max-Q Design that's disabled via ACPI and boot-args) RAM: 12 GB Motherboard/Laptop Make and Model: MSI GF63 Thin 10SXCR Audio Codec: ALC223 Ethernet Card: RTL8111HS-CG Wifi/BT Card: Intel 802.11ax Wi-Fi 6 + Bluetooth v5.1 Touchpad and touch display devices: HID-Compliant Touchpad (Used VoodooI2C for touchpad) BIOS revision: -

Use linux to find out your audio codec (ALC...) and use this to narrow down the layout ids you could use. Try all of them and see which one works. Good luck!

So..i have a Lenovo Legion 7i Laptop with Realtek ALC287 audio codec, i've used layout-id 11 and 21, (21 seems to be better, since an internal and external mic device seems to be appearing on the System Preferences) however, although slider, volume, works...i still got no audio (both input and output), been surfing around and got to this link : https://github.com/acidanthera/AppleALC/wiki/Dumping-processing-coefficients
