For this guide, I will be using my Asus X99-E WS board. Settings will be very similar for other Asus boards.
Hackintosh will really test your trial and error abilities. Stay patient and keep trying. Here is the framework I use whenever I change/add hardware to my Hackintosh.
1. Upgrade your BIOS
In general you should upgrade your BIOS to the latest stable version. But certain versions may cause issues with macOS and prevent it from booting. As was the case with BIOS v3402 for my board. I needed to downgrade to v3302.
Download the latest stable BIOS direct from your motherboard manufacturer only. For Asus boards, it's called "EZ Flash."
2. Change BIOS settings
Intel Speedstep Technology =
Disabled (Causes CPU multiplier to stick to the CPU default and you loose performance)
xHCI Mode =
EHCI support =
Legacy USB =
Fast Boot =
Setup Mode =
Serial Port =
Asmedia USB 3.0 Controller =
Off (USB 3.0 still works on my machine, but this seemed to cause issues)
CSM (Compatibility Support Module)
Clear Secure Boot Keys (if any)
Avoid any overclocking during this stage, it will be difficult to
Exit > Save Settings and Reset
Conservative Overclock Settings
After this, you're ready to create your Clover USB installer and move ahead!
