Help Needed with RTX 4070 in PCI Slot 1 Stopping Hackintosh Boot

[santosh mareddy]

Hi everyone,

I’m facing an issue with my Hackintosh setup, and I could really use some help. My RTX 4070 GPU in PCI Slot 1 is causing my Hackintosh to fail to boot. I’d like to disable the RTX 4070 for Hackintosh and use only the AMD Radeon RX 6600 in Slot 2 for macOS.

Here’s my PC configuration:

• CPU: Intel i9 13900K
• GPU Slot 1: RTX 4070
• GPU Slot 2: AMD Radeon RX 6600
• Motherboard: ASUS Prime Z790-A WiFi

I would appreciate any advice on how to disable the RTX 4070 specifically for macOS, while keeping it active for Windows, and how to ensure my RX 6600 is the default for Hackintosh. Any tips, kexts, or BIOS settings that could help would be great full

I tried this method but no use, when I place my rx6600 GPU in the second slot and remove other RTX 4070 GPU from slot 1 my Hackintosh is still stuck at booting

Forgetting about the SSDT for a minute if you remove the Nvidia card does the system boot with the AMD card in the second slot? Just an observation, being that you have an intel based system, you probably get more support from a site that isn't so focused on AMD systems.

You need to hide the Nvidia GPU in OC.

In my setup it worked. I also set in Bios the 2nd PCIE slot as the main Card.
