AMD Ryzen 5 3500U + Vega 8 - macOS Tahoe 26.4 Setup freezes

Hey everyone,

Hardware:

\- Lenovo IdeaCentre 3 07ADA05

\- CPU: AMD Ryzen 5 3500U

\- GPU: AMD Radeon Vega 8 (integrated)

\- SSD: Samsung 512GB

\- Bootloader: OpenCore 1.0.4

Problem:

macOS Tahoe 26.4 installation works and boots to Setup screen, but freezes at country selection. Keyboard and mouse not responding.

Error in verbose mode:

\- Couldn't alloc class "IOVersatileHWA"

\- NootedRed Patcher: Failed to solve '\_\_ZZN37AMDRadeonX5000\_AMDGraphicsAccelerator19createAccelChannelsEbE12channel'

What I tried:

\- NootedRed Research Release (latest)

\- AMFIPass.kext

\- boot-args: -v npci=0x3000 -amd\_no\_dgpu\_accel nootedred=0

\- UTBMap rebuilt

\- NVRAM reset

Any help appreciated!
