How to Fix Will Tiger Lake theoretically work with an external discrete GPU via M.2?

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
  2. Ensure Metal acceleration is fully supported for your macOS version.
  3. Update Lilu and WhateverGreen to the latest versions.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

As in title. Have been on OpenCore until I got upgraded to a Tiger Lake laptop.

I am planning on buying a Big Navi GPU and connecting it to the M.2 slot on my laptop via ADT-Link R43SG 4.0 (one of the few PCIe x16 to M.2 adapters). I am quite confident the CPU itself will be supported by spoofing as Ice Lake, but I am skeptical whether OpenCore would recognize the M.2-connected GPU.

From research, it seems an "internal" external GPU via M.2 would be better in compatibility than a TB3.
