How to Fix GPU Buyers guide - HD 5870 for High Sierra
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:
Hello, should I get a Sapphire HD 5870? Would patching program get it to work natively in macOS like the official Mac Pro HD 5870s?
I have a Mac 5770, could I use that to flash?
Specs: GA Z77-UD3H
CPU: 3570K 4.2-4.4gHz
16GB HyperX
EVGA GTX 570
WD SN550 with PCI riser card(wboot drive for Mavericks)
Intel SSD for mavericks
My main hang is a GTX 570, that works well in Mavericks, but has a black screen right before the login menu in High Sierra. I boot with iGPU and nv_disable=1.
I could disable the GTX570, however the HD4000 has similar graphical glitches, with iGPU, than nv_disable=1, and HD4000 seems slow in windows.
The other option would be a Sapphire RX 470, which I'm sure will work with High sierra, however won't work with mavericks unless I keep the GTX 470 in as well. I have 750watt PSU.
Thanks.
EDIT: Apparently the GTX 570 is part of the problem
