Fixing Red and Blue Color Inversion Issue on Big Sur Hackintosh

Introduction

If you're experiencing a strange issue where red and blue colors are inverted on your Hackintosh running Big Sur, along with some UI elements being slow, this guide will help you diagnose and resolve the problem.

Step-by-Step Guide

1. Confirm SMBIOS Configuration:

   • Ensure that your SMBIOS configuration is set correctly. Since you mentioned using an iMac18,2 profile, it's generally a compatible choice. However, double-check that it matches your hardware as closely as possible.

2. Graphics Configuration:

   • If you are using the integrated GPU (IGPU) on your i5-7400, make sure you have the correct framebuffer settings. Some IGPU-related issues can cause color problems. Research the recommended framebuffer settings for your specific Intel IGPU model and try adjusting them in your bootloader configuration.

3. Kexts and Drivers:

   • Check that you have the appropriate graphics-related kexts and drivers installed. Ensure that they are up to date and compatible with Big Sur.

4. Graphics Injection:

   • Depending on your bootloader (Clover, OpenCore, etc.), ensure that you have proper graphics injection configured. This may involve setting the right device properties, framebuffer, and connectors for your IGPU.

5. Framebuffer Patching:

   • If necessary, apply framebuffer patches for your IGPU in your bootloader configuration. These patches can correct various graphical issues.

6. GPU Hardware Acceleration:

   • Confirm that hardware acceleration is enabled for your IGPU. You can check this in the "About This Mac" section. If it's not enabled, it may lead to UI slowness and graphical glitches.

7. Red and Blue Color Inversion:

   • To address the color inversion issue specifically, consider creating a custom color profile for your monitor. Go to "System Preferences" > "Displays" > "Color" and create a custom profile that corrects the red and blue inversion. This may help alleviate the color problem.

8. Check for macOS Updates:

   • Ensure that your macOS installation is up to date. Apple often releases updates that include bug fixes and compatibility improvements.

9. Reset NVRAM:

   • Sometimes, resetting the Non-Volatile Random-Access Memory (NVRAM) can resolve graphical issues. Reboot your Hackintosh and press the necessary key combination (usually Command + Option + P + R) to reset NVRAM during boot.

10. Community Support:

    • If the problem persists, reach out to the Hackintosh community for assistance. Forums and Reddit groups dedicated to Hackintoshing can provide valuable insights and solutions based on your specific hardware and software configuration.

Conclusion

Fixing the red and blue color inversion issue on your Big Sur Hackintosh, along with addressing UI slowness, involves configuring your graphics settings, ensuring correct kexts and drivers, and potentially creating a custom color profile. Make sure your hardware is fully compatible, and stay updated with macOS releases and community support for the latest solutions to any issues you encounter. With the right adjustments, you can enjoy a stable and visually correct Hackintosh experience.
