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.

To be honest mate, you'd be better off building a cheap b450/b550 AMD hackintosh and using the RX 6600 in there.

I myself, have a 2nd system with a 4070 in, and keep that just for gaming under the tv with a controller... I use RX 6800 system in my sig as a hackintosh at the desk and dual boot Windows 11 for when I want to play multiplayer games with a keyboard and mouse with the RX 6800...

Considering how cheap b450/b550 is now, especially second hand, you really should consider this, especially if you make a quiet/small MITX system as I've chosen to do, which will fit anywhere with limited space...

I'm pretty sure that if you have 2 graphics cards, your 4070 and everything else will be running in PCI-E 3.0 mode due to the lanes being used on the 2nd slot... Not a 'huge' issue, but still worth mentioning, depending on how much other stuff is plugged in and using the lanes...
