Guide:

Introduction: If you are facing issues with the Nvidia Kepler GPU, particularly a black screen when running the iOS simulator in Xcode on MacOS Sonoma 14.2.1, follow this guide to troubleshoot and resolve the problem. Please note that Nvidia Kepler GPUs are not officially supported on recent macOS versions, and workarounds may be needed.

Requirements:

• MacOS Sonoma 14.2.1 installed on your Hackintosh
• OpenCore or appropriate bootloader
• Knowledge of Hackintosh configurations

Step 1: Update Lilu and WhateverGreen:

1. Ensure that you have the latest versions of Lilu and WhateverGreen kexts.
2. Download the latest releases from their respective repositories and replace the existing kexts in your EFI folder.

Step 2: Use OCLP for GPU Patching:

1. If you are using OpenCore Legacy Patcher (OCLP), ensure that you have applied the necessary patches for your Nvidia Kepler GPU.
2. Follow the instructions provided by the OCLP community for patching Kepler GPUs on Sonoma.

Step 3: Verify Graphics Settings:

1. Open your OpenCore configuration file (config.plist) using a plist editor.
2. Check if the Graphics section is configured correctly for your Nvidia GPU.

Step 4: Try Different Boot Flags:

1. Experiment with boot flags related to Nvidia GPUs. Common flags include nv_disable=1 or npci=0x2000.
2. Test different combinations to see if any resolve the black screen issue.

Step 5: Consider Alternative Bootloaders:

1. If the issue persists, consider trying alternative bootloaders like Clover or different versions of OpenCore to check for compatibility.
2. Some users have reported success with specific bootloader versions and configurations.

Step 6: Community Support:

1. Engage with the Hackintosh community for support and guidance.
2. Share your experiences and seek advice on forums or relevant platforms.

Step 7: Evaluate GPU Upgrade Options:

1. Due to limited official support for Nvidia Kepler GPUs on recent MacOS versions, consider exploring GPU upgrade options.
2. Check for supported AMD GPUs or Nvidia GPUs with native MacOS drivers.

Conclusion: Resolving the Nvidia Kepler issue on MacOS Sonoma 14.2.1 may require a combination of updating kexts, applying patches, and experimenting with boot flags. By following these steps and seeking community support, you can optimize the compatibility of your Hackintosh with Nvidia Kepler GPUs. Good luck with resolving the black screen issue in the iOS simulator on Xcode!
