Tahoe not working on Ryzen 5 3500u

[rakismac32]

So currently i have a successful install of macOS Ventura 13.7.8 on my ThinkPad T495s with these specifications:

CPU: AMD Ryzen 5 PRO 3500U w/ Radeon Vega Mobile Gfx
RAM: 16GB DDR4 2400MHz
SSD: 256GB NVMe
Wifi card: Intel Wireless AC 9260
iGPU: AMD Radeon Vega 8 Graphics

My current working efi build is mostly 'inspired' by this repo: https://github.com/PersistentCloud/Thinkpad-T495-Hackintosh

but when i try to upgrade to tahoe i simply get a kernel panic after reboot and trying to get into the installer assistant phase

Things i've tried:
Updating nootedred to a nightly build 0.9.0
Regenerating smbios to macbookpro 15,2

Any ideas to what i should change further to get tahoe working?

Forgot to include, here's my current EFI build

Your config is a bit of a mess if I'm honest, for a start you put the patches in the wrong place!. I've never owned a Laptop hackintosh so I wouldn't be the best person to ask, but if you already have a successful installation of Ventura I suggest looking at the structure of that config to get a better idea of what you did wrong.

Thanks for the response! it's my first time ever getting a reply in a forum site, fun fact.

Anyway, if the misplaced patches you're referring to is patches.plist file in EFI/OC, i remember it's a leftover from AMD_Vanilla patch which the contents i have copied to the config.plist in Kernel -> Patch, so i don't think it's being used by the bootloader.

However, i feel like my config is missing patches specifically required in Tahoe or Sequoia, since this same config can still boot Ventura, unlike other efi build i tried which won't even boot Ventura.

Have you adapted your USB map for Tahoe?

What makes you think you need specific patches for Tahoe or Sequoia? You have not mentioned Sequoia otherwise…

Have a look at the attached revised EFI, it should work with Sequoia, once you have added the SMBIOS data for a MacBookPro16,3 system to the config.plist.

For this to work in Tahoe, the USBMap.kext needs to be updated, i.e. New USB port and name entries added to the kext. This can be done by booting in to an existing macOS (Ventura) and using Hackintool version 4.1.5 Export a new USBPorts.kext, based on the current USB configuration.

For the record, USBToolBox.kext and UTBMap.kext don't work in Tahoe, as they lack this new naming configuration imposed by Apple when Tahoe was released.

I have cleaned up your original EFI - Tahoe folder, removing any unnecessary or duplicate entries. It should hopefully boot quicker than your previous setup, once you have added the MBP 16,3 SMBIOS data to the revised config.plist. Let us know how you get on with this EFI.

The EFI attached above would probably work with Tahoe as well as Sequoia, but there would be a few components that either won't work or won't work correctly. Those being the Intel AC9620 WiFi card, the USB ports, including the internal Bluetooth and built in Webcam and the Realtek Audio codec.

All of these components/devices except the USB ports and Webcam require specific fixes using OCLP-Plus or a similar post install application, plus specific kexts and config.plist entries to enable or block specific kexts.

As previously stated the USBPorts.kext needs to be updated to work with Tahoe, this will probably fix the USB connected Bluetooth and Webcam devices.

However, some systems don't boot Tahoe when the OCLP kexts are enabled or blocked in the config.plist. My 2 x B550 systems being prime examples. I have tried numerous OCLP versions and forks but can't for the life of me get the Broadcom WiFi working in Tahoe on these two systems. My X570 and B650E systems work perfectly with Tahoe, using the same native Apple Broadcom WiFi/BT cards.
