How to Fix macOS Installer screen is black until it wakes up from sleep
Graphics issues usually stem from an unsupported GPU, missing acceleration patches, or incorrect boot arguments.
Quick Fix Steps
- Verify GPU support: Check if your GPU model is natively supported in your target macOS version via WhateverGreen documentation.
- Update kexts: Ensure Lilu and WhateverGreen are current and loaded before other GPU-related kexts.
- Check boot arguments: Add
-v keepsyms=1 debug=0x100for debugging, oragdpmod=pikerafor modern AMD cards. - Test Metal support: Open About This Mac > System Report > Graphics and confirm Metal is listed.
Verification
- Graphics acceleration is smooth (not CPU-bound).
- Metal is reported in System Information.
- No GPU-related kernel panics on boot.

Original Question: "macOS Installer screen is black until it wakes up from sleep"
Hello guys,
I've decided to give my PC a bit of hackintoshing. I've actually done it on older computers a few times without too many issues. However, this time it's getting a bit troublesome. Since this is my first time using Opencore, this could be my fault, though when I also tried with Clover bootloader, where in both cases the screen is completely black in installer until the computer goes to sleep and then wake it up again. In Clover's case I also had another issue with not being able to install it but I decided to talk about it only after solving this issue and if it happens again.
The specifications for my PC are:
ASUS motherboard H87M-PRO
Intel Core i7 4770s
AMD Radeon RX 470
INTEL SSDSC2BB240G4
Here's the log of Opencore: https://pastebin.com/sRsS3W2r
Here's also config.plist, just in case: https://pastebin.com/THEFYySW
Thanks in advance!
