Need assistance adapting EFI for macOS Tahoe (Ryzen 9 7950X3D + RX 6900 XT)

[hinkin]

Hi everyone,

I’ve been trying for several days to get my EFI configuration working for macOS Tahoe on my system, but I haven’t had any success so far.

Hardware Configuration​

• CPU: AMD Ryzen 9 7950X3D
• Motherboard: Gigabyte X870 AORUS ELITE WIFI7
• RAM: 64GB DDR5 5000MHz
• GPU: AMD Radeon RX 6900 XT 16GB
• Network: Realtek RTL8125B
• Wi-Fi/Bluetooth: Fenvi T919 PCIe WLAN Card

I currently have a fully working EFI for macOS Sequoia, but I need assistance in adapting or fixing it so that it can properly install and run macOS Tahoe on this setup.
I’m sharing my current EFI folder for anyone interested in helping improve or create a Tahoe-compatible version.

Any help or suggestions would be greatly appreciated.

Thank you in advance!

Have you updated your USB configuration to include the new entries required for Tahoe?

Are you using the latest version of the AMD Kernel patches?

Have you temporarily disabled WhateverGreen.kext, so it doesn’t cause a kernel panic while running the Tahoe installer? It can be enabled after the Tahoe installation has completed.

Are you aware that the OCLP root patches for Broadcom WiFi don’t work in Tahoe, as it needs to be updated and this hasn’t happened yet.

Are you aware that AppleALC.kext requires AppleHDA to be installed for the builtin audio codec to work? This isn’t relevant for those with a USB audio device.

Most people who have successfully updated to Tahoe used a minimal EFI when running the update, I.e only the really essential kexts present and enabled.

Hi Edhawk,

Thank you again for your help!
I’ve prepared a minimal EFI (Tahoe Install) based on your suggestions - WhateverGreen disabled, USBInjectAll + XhciPortLimit enabled, and AMD patches extended to Darwin 25.x.

I’m attaching the installation version here.
If you have time, could you please take a look and let me know if anything needs to be fixed or improved before I proceed?
I’ll wait for OCLP to update their Broadcom patches to get Wi-Fi working again.

Thanks in advance!
