Resolving Black Screen on First Boot with Radeon RX 480 in macOS Ventura

Based on the error description, it seems the system is booting but not outputting any video, leading to a black screen despite the system being active (as indicated by the sounds and response to mouse movements). This is typically due to issues with the GPU drivers or configuration.

Hackintosh Solution Guide:

Step 1: Verify GPU Compatibility

  • The Radeon RX 480 is generally supported in macOS as it is part of the AMD Polaris family, but ensure it is compatible with Ventura specifically.

Step 2: Confirm Proper Kexts

  • Ensure that you have WhateverGreen.kext installed, as it's required for AMD GPU support. Also, ensure Lilu.kext is in your EFI, as WhateverGreen requires it to function.

Step 3: Check config.plist Settings

  • In your OpenCore config.plist, confirm that the NVRAM -> boot-args section includes agdpmod=pikera. This boot argument is necessary for certain AMD GPUs to prevent black screen issues.

Step 4: Validate Framebuffer Patching

  • If you have applied any framebuffer patches for your GPU in the DeviceProperties section of your config.plist, double-check them for accuracy.

Step 5: Ensure Correct SMBIOS

  • Ensure you're using an SMBIOS that is appropriate for your hardware. For the i7 2700K and RX 480, an iMacPro1,1 or a similar SMBIOS might be suitable.

Step 6: Rebuild Kext Cache

  • Boot into macOS using the USB stick, open Terminal, and run the following command to rebuild the kext cache: sudo kextcache -i /

Step 7: Update OpenCore and Kexts

  • Verify you're using the latest version of OpenCore and all kexts are updated, as older versions may have compatibility issues with new macOS releases.

Step 8: Check Display Connections

  • Verify that your monitor is connected to the RX 480 and not the motherboard's HDMI/DP, as the integrated graphics of the Sandy Bridge CPU may not be supported in Ventura.

Step 9: Remove Unnecessary Kexts

  • Remove any kexts that are not necessary for your system. For instance, if you don't have an Apple T2 chip, you might not need AppleMCEReporterDisabler.kext.

Step 10: Disable Integrated GPU

  • If your system BIOS allows, disable the integrated GPU to ensure that macOS uses the RX 480 for video output.

Step 11: Seek Community Help

  • If the issue persists, seek assistance from the Hackintosh community on forums like tonymacx86, Reddit's /r/hackintosh, or InsanelyMac. Be prepared to provide your EFI folder for review and details about the steps you've already tried.

Step 12: Consider macOS Compatibility

  • If your hardware is particularly old or uncommon, it may have limited support in the latest version of macOS. Consider whether a downgrade to an older macOS version may offer better compatibility.

Conclusion: By following these steps, you should be able to resolve the black screen issue after the first boot of macOS Ventura on your Hackintosh. Remember, trial and error is a large part of the Hackintosh process, and patience is key.

OC : Mac OS Ventura sucessfully installed, but boot into Black screen during first boot

Hello, I sucessfully created a bootable USB, it boot into opencore and into macOS Recovery Environment without any problem, i can even download the installer via the online install method from it, after a few routine restart, the system boot into new user setup mode, the thing is it boot into black screen , the monitor receive the signal output from the gpu but it's all black, after a while the sound assisted setup assistant started to activate by playing setup assist sound on my USB speaker, and after a few moment of idle the screen goes to sleep, but i was able to bring it back on just by moving the mouse, the screen lit up but remains black. all of this sign pointing that the OS succesfully installed but the output is black screen,

Sandy Bridge CPU require significantly more effort and configuration in order for it to work in Mac OS ventura especially in my specific configuration which is an Intel Core i7 2700K paired with Gigabyte Z77X-UD5H with Radeon RX480 Graphics. all of this hardware Pairing require the following kext in order to make it work.

Kext Used:

AMFIPass.kext : Allows booting macOS 12+ without disabling AMFI

AppleALC.kext : enabling native macOS HD audio

AppleIntelCPUPowerManagement.kext : for re-enabling SMC CPU Power Management in macOS Ventura and newer

AppleIntelCPUPowerManagementClient.kext : Subcomponent of AppleIntelCPUPowerManagement.kext

AppleMCEReporterDisabler.kext : Required for MacPro7,1 SMBIOS to boot.

ASPP-Override.kext : Prioritizes plugin-type 0 over plugin-type 1 so SMC CPU Power Management works

CryptexFixup.kext : Required for installing and booting macOS Ventura on systems without AVX 2.0 support, Very important in order to get Radeon Polaris GPU to work

FeatureUnlock.kext : Unlocks aditional feature such as NightShift and AirPlay to Mac

Lilu.kext : Generic kext patcher works in tandem with WhateverGreen.kext

RealtekRTL8111.kext : Drivers for Atheros Gigabit LAN

RestrictEvents.kext : Forces VMM SB model, allowing OTA updates for unsupported models on macOS 11.3 or newer

USBToolBox.kext : UTBMap.kext sub component, must use in tandem with it.

UTBMap.kext : USB mapping created using USB tool box in windows, it varies for every build, no ready made UTBMap.kext available, so we need to made our own, without it USB port won't work.

VirtualSMC.kext : Advanced Apple SMC emulator Require Lilu.kext in order for it to work, compulsory Kernel extension for Hackintosh to boot.

WhateverGreen.kext : require Lilu.kext in order to work, providing Various patches necessary to select GPU.

​

Additonal kernel patches had to be added to the Opencore Config file in order for it to boot

​

Additional Kernel Patch Added

Force FileVault on Broken Seal : for file vault

"SurPlus v1 - PART 1 of 2" : first part of SurPlus patches, required for Sandy Bridge and older.

"SurPlus v1 - PART 2 of 2" : second part of SurPlus patches.

Fix PCI bus enumeration (Ventura) : Fix PCI bus enumeration patches fix internal PCIe devices showing up as express cards in the menu bar

A link to the EFI file Wouild be provided Below

Had anyone successfully overcame this issue, any helpful responses are very much appreciated.

​

thank you.
