The image you've shared indicates that your Hackintosh is experiencing a black screen issue after attempting to boot, which is typically related to GPU acceleration problems. However, the provided information in the image is not enough to give a precise solution. Here are general steps you can follow to address this issue:

1. Boot in Verbose Mode: Always boot in verbose mode (-v boot flag) when you're troubleshooting. This way, you can see what's happening during the boot process.

2. Check BIOS Settings: Ensure that the BIOS settings are configured correctly for Hackintosh. This includes setting the integrated graphics as the primary display output and configuring the DVMT pre-allocated memory to the recommended value (typically 64MB or higher).

3. Review Your EFI Folder: Make sure that your EFI folder is set up correctly. The EFI folder should contain the necessary drivers, kexts, and a properly configured config.plist file. Key kexts include WhateverGreen.kext and Lilu.kext, which are essential for GPU acceleration.

4. Update Kexts: Make sure all your kexts are up-to-date, particularly WhateverGreen, as it's crucial for Intel graphics support.

5. Frame Buffer Patching: For Intel HD graphics, proper frame buffer patching is often necessary. Check that your config.plist has the correct frame buffer patch for your specific Intel GPU.

6. Device Properties: Ensure that the DeviceProperties section of your config.plist has the correct platform-id and device-id for your UHD 620. The AAPL,ig-platform-id should be set for the UHD 620, and you may need to experiment with different values to find the one that works for your setup.

7. Clear NVRAM: Sometimes, old or incorrect values in NVRAM can cause issues. Clear the NVRAM to ensure there are no lingering settings that could be causing problems.

8. Consult the Hackintosh Community: If the above steps do not resolve the issue, share the verbose boot screen, your config.plist, and hardware details with Hackintosh forums like tonymacx86 or Reddit's /r/hackintosh for more targeted assistance.

9. Consider Dedicated Graphics: If you continue to have issues and have access to a compatible dedicated GPU, you might want to try adding it to your system for better support.

It's important to note that without specific error messages or a look at your config.plist, this advice is quite general. You will need to adapt these suggestions based on the exact output of the verbose boot and the specifics of your hardware.
