How do I enable Nvidia GPU support?

To enable Nvidia GPU support on a Hackintosh, you need to consider the following:

1. GPU Compatibility: MacOS has limited support for Nvidia GPUs, especially in the newer versions. If you have an Nvidia GPU from the GTX 600 or 700 series (Kepler architecture), these are natively supported up to macOS Big Sur because they support Metal. For GTX 900 and 1000 series (Maxwell and Pascal architectures), they are supported only up to macOS High Sierra (10.13) because Apple dropped support for these architectures in later versions.

2. OpenCore Legacy Patcher (OCLP): This is a tool used to add support for older hardware in newer versions of macOS. It can enable support for older Nvidia GPUs that were supported in past macOS versions. However, as noted in the information you provided, while OCLP can make GTX 600-700 series work with the newest macOS, the GTX 900-1000 series will have limited functionality because they lack Metal support. For GTX 16 series and newer, they are not supported and cannot be made to work with macOS.

Here’s what you can do based on your scenario:

• If you have a Kepler-based Nvidia GPU, you should not need any special patches for macOS versions that support Metal (up to Big Sur).
• If you have a Maxwell or Pascal Nvidia GPU and want to run macOS High Sierra (10.13), you can use it without special patches, but you will not be able to upgrade to a newer macOS version without losing GPU support.
• For newer macOS versions, you can use OCLP to add support for Kepler GPUs. However, keep in mind that performance and compatibility might not be perfect.
• For GTX 900-1000 series on newer macOS versions, even with OCLP, the experience may not be satisfactory due to the lack of Metal support.
• GTX 16 series and newer are not supported on any macOS version.

To use OpenCore Legacy Patcher:

1. Download OpenCore Legacy Patcher from its official website or GitHub repository.
2. Follow the instructions provided by OCLP to create a patched EFI folder that includes support for your Nvidia GPU.
3. Replace your existing EFI folder with the patched EFI, and attempt to boot.

Remember, running a Hackintosh setup with unsupported hardware can be challenging and may not result in a stable system. Always back up your data before making changes to your system, and consider that there may be limitations to what you can achieve with unsupported GPUs in macOS.
