Enabling DRM Support on Hackintosh with i9-9900KF and RX 5700

Guide:

If you're experiencing issues with DRM support on your Hackintosh setup with an i9-9900KF CPU and an RX 5700 GPU, follow these steps to troubleshoot and potentially resolve the problem:

1. Choose the Right SMBIOS:

   • Since you're aiming for stability and future-proofing, use the iMacPro1,1 SMBIOS.
   • This SMBIOS expects an iGPU, but since you're using a dedicated GPU (RX 5700), you'll need to apply certain patches and boot flags to ensure compatibility.

2. Injecting Properties for AMD GPU:

   • Open your config.plist file using a plist editor such as ProperTree.
   • Under the DeviceProperties section, inject the properties specific to your RX 5700 GPU. You can use tools like Hackintool to generate these properties automatically.
   • Ensure that you inject the correct framebuffer and connector patches for your GPU model.

3. Boot Flags and Kernel Extensions (Kexts):

   • Experiment with boot flags related to AMD GPUs to see if any specific flags help with DRM support. Common flags include -radpgu, -radvesa, and -radgva.
   • Install the necessary kernel extensions (kexts) for your AMD GPU, such as WhateverGreen.kext and Lilu.kext. These kexts help with GPU recognition and functionality.

4. Verify System Integrity Protection (SIP):

   • Ensure that SIP is disabled or properly configured. SIP can sometimes interfere with certain system modifications and DRM functionality.
   • You can check SIP status by booting into Recovery Mode (Cmd + R at startup) and opening Terminal, then running csrutil status.

5. Update and Patch Your macOS Installation:

   • Make sure you're using the latest version of macOS compatible with your hardware.
   • Apply any necessary patches or updates to your macOS installation, especially if there are specific fixes related to DRM support or GPU compatibility.

6. Monitor Logs and Debugging:

   • Check system logs for any errors or warnings related to DRM or GPU functionality. Console.app can be useful for this purpose.
   • Use verbose boot mode (-v flag) during startup to observe any errors or issues that occur during the boot process.

7. Community Support and Forums:

   • Seek assistance from online forums and communities dedicated to Hackintosh enthusiasts. Websites like InsanelyMac and Reddit's r/Hackintosh are valuable resources for troubleshooting and getting advice from experienced users.

8. Consult Hackintosh Experts:

   • If you're still encountering issues, consider reaching out to experienced Hackintosh users or consultants who may be able to provide personalized assistance and guidance.

By following these steps and experimenting with different configurations, boot flags, and kernel extensions, you can potentially resolve DRM support issues on your Hackintosh setup with an i9-9900KF CPU and RX 5700 GPU. Remember to backup your system before making significant changes and proceed with caution.
