How to Fix Has anyone successfully gained full compatibility with a Sapphire AMD Radeon R9 390 Nitro on a Hackintosh (OC)?
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
- Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
- Ensure Metal acceleration is fully supported for your macOS version.
- Update Lilu and WhateverGreen to the latest versions.
Verification
- Reboot and verify if the functionality is restored and stable under typical usage.
Original Question:
I was wondering if anyone has had a successful run with the aforementioned graphics card? I‘m running Big Sur (initially installed Catalina, and then used Software Update to update to Big Sur); I installed it — Catalina — by following OpenCore‘s guide.
My specifications are (if needed):
– Intel Core i5-8400 (Coffee Lake);
– 16 GB DDR4 RAM; 2133MHz;
– Sapphire AMD Radeon R9 390 Nitro;
– B365M DS3H;
– KINGSTON SA400S37240G (256GB)
Running BigSur v11.2.2.
I also wish to know that if anyone, who‘s had a successful run with the graphics card, has had to patch anything manually? Connector ports, spoofing the GPU, ect.
Thank you for all the replies in advance!
