Fixing Display Issues on Lenovo Y700-15ISK with OpenCore for macOS Ventura

Based on the description of your issue with the Lenovo Y700-15ISK and OpenCore while installing macOS Ventura, it seems like you're experiencing a problem with the internal display output during the boot process. Here’s a guide to help you troubleshoot and potentially resolve this issue:

Guide Step by Step:

1. Check EFI Folder Structure:

   • Ensure that your EFI folder is correctly set up for OpenCore. It should include the necessary drivers, kexts, and ACPI patches.

2. Graphics Configuration:

   • Since you have an Intel HD 5300 GPU, ensure you're using the correct ig-platform-id for this iGPU in your config.plist.
   • Verify that your GTX 960M is indeed disabled in BIOS, as macOS does not support most Nvidia GPUs and it can cause conflicts.

3. SMBIOS Configuration:

   • For an Intel Skylake processor like the i7-6700HQ, using a Skylake SMBIOS like MacBookPro13,1 might be more appropriate than spoofing to a Kaby Lake SMBIOS.
   • Incorrect SMBIOS can lead to compatibility issues, including display problems.

4. Display Output Settings:

   • In your config.plist, under DeviceProperties, ensure that the display output is set to route through the internal display.
   • You may need to experiment with different framebuffer patching settings to get the internal display working.

5. Audio Codec Verification:

   • Identify your specific ALC audio codec model. This can be crucial for getting audio working properly.
   • Use an appropriate kext, like AppleALC, with the correct layout-id for your audio codec.

6. Check ACPI Patches:

   • Ensure that your DSDT and SSDT patches (if you're using them) are correctly applied and are compatible with macOS Ventura.
   • Commonly needed patches include those for battery management, brightness control, and disabling discrete GPUs.

7. Update Kexts and OpenCore:

   • Make sure you are using the latest versions of OpenCore and all the kexts. Outdated software can cause compatibility issues.

8. Troubleshooting with Verbose Mode:

   • Boot in verbose mode (using the -v boot argument) to see where the boot process might be failing.
   • Kernel panic logs or error messages can provide valuable clues to the underlying issue.

9. HDMI Output as a Temporary Solution:

   • While troubleshooting, using an HDMI output as you're currently doing can be a temporary workaround.
   • However, the goal should be to get the internal display working correctly.

10. Seeking Community Help:

    • If you're still having trouble, consider seeking assistance from the Hackintosh community forums. Provide detailed information about your hardware, EFI setup, and the issues you’re experiencing.

11. Backup and Documentation:

    • Always keep backups of your working EFI and any changes you make.
    • Documenting your process can help in troubleshooting and might assist others with similar hardware.

Remember, creating a Hackintosh can be a complex process, especially with laptop hardware. It often requires a bit of trial and error to get everything working smoothly.
