Request for EFI: Install macOS 26 with Integrated GPU Support
Hi everyone, I'm seeking help to find a compatible EFI for installing macOS 26 on my Lenovo desktop. My main goal is to get the integrated GPU fully functional, and I’ve listed all hardware details below for reference:
Hardware Configuration
- Motherboard: Lenovo 3148 (BIOS version: M2CKT53A, released 03/20/2024)
- CPU: AMD Ryzen 5 PRO 2400G (Quad-Core, 3600 MHz)
- Integrated GPU: AMD Radeon(TM) Vega 11 Graphics (2 GB VRAM)
- Memory: 6066 MB DDR4-2400 (Single Channel)
- Storage: Fanxiang S500Q 512GB NVMe SSD
- Network Adapter: Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter
- Audio: Realtek ALC662, AMD K17.1 Audio Processor
- BIOS Settings: Secure Boot disabled, UEFI boot mode enabled
Key Requirements
- Successfully install macOS 26 (stable system boot without kernel panics).
- Full support for the AMD Vega 11 integrated GPU (proper display output, GPU acceleration for daily tasks, no graphical glitches).
- Compatibility with basic hardware: Ethernet, audio, USB ports, and NVMe SSD.
Current Situation
I’ve tried configuring EFI with OpenCore but encountered issues with GPU recognition—macOS either fails to detect the Vega 11 GPU or runs with limited resolution and no acceleration. I’ve confirmed the hardware is fully functional on Windows 10 LTSC.
Request
If anyone has a working EFI for a similar setup (AMD Ryzen 5 PRO 2400G + Lenovo motherboard + macOS 26) or can guide me on modifying the EFI to enable the integrated GPU, please share your files or tips. Any help with kext selection (e.g., Lilu.kext, WhateverGreen.kext) or DeviceProperties tweaks for Vega 11 would be greatly appreciated!
Thank you in advance for your support!
