Dual screen artifacts unless 1 is plugged in after boot

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

Using lilu and whatevergreen.kexts. I can boot with 1 monitor (displayport) and can plug the other monitor (hdmi), and both work well. But if I try to boot with both monitors plugged in, I get unwatchable unusable artifacts on both screens. Everywhere I have searched all over the internet this is a common problem but there were no solutions. I would appreciate any help. Thanks Johnm

try using hdmi/dvi cables only

Thank you but I only have 2 outputs. 1 is a DisplayPort that I have plugged into a TV set, the other is hdmi. Are you saying I need to change the DP output to an hdmi, right? I don't have a dvi connector anywhere. I could buy a DisplayPort to hdmi adapter if that's what you mean. Thanks for the help. Johnm
