Note: You're nothing but an a-hole if you sell EFI folder (config) that's readily available for free.

Budget X79 Xeon Build

EFI Folder (Clover) and config required for an X79 8-Core Xeon macOS High Catalina Hackintosh.

System Specs

README

• Proceed with caution.
• Tested on macOS Catalina 10.15.2.
• EFI folder is N/A for Opencore bootloader. Go ahead though, if you know what you're doing.
• Applicable for direct upgrade from High Sierra or Mojave.
• The EFI folder is applicable to SSD hot-swap also. ie, if you're planning to swap SSD from a MacBook Pro to ThinkPad 530.

Before You Proceed

You should modify the EFI (a lot) if your system specs are different. I use the settings for my motherboard. Huanan X79 is another motherboard similar to mine. The CPU type 0x0a01 I set in Clover is only applicable to 8-core CPU models. You should edit that out if your CPU config is different. Also, note that I’ve manually set my system memory info (4x 8GB) within the SMBIOS in Clover. You should edit that as well.

Starter EFI

If things go south, use the clover settings attached in the starter-EFI folder. You can use it as a starter. But then you've to tweak settings a bit more.

About Kexts

• Catalina update broke my LAN. I use a WiFi adapter for the time being. I added Realtek WLAN kexts (RtWlanU & RtWlanU1827) to use with the Comfast USB Wi-Fi adapter. You should edit the config. according to your preferences.
• I’ve got a lot of other Kexts in place for sensors, just ignore or remove those.

BIOS Settings

You may proceed with the default settings for Ant Country X79 Basic. It may vary if you're using another motherboard.

What Doesn’t Work?

• Ethernent (for the time being). I use a WiFi adapter, so no plans to fix that soon.
• iMessage & Facetime.(it'll work after SMBIOS edits)

How to create a bootable macOS Catalina USB install drive? (on Windows)

1. Install Transmac on a Windows machine. It has a 15-day trial period and works flawlessly flashing DMG files to USB.

9. Locate the USB drive in DiskGenius. Delete the EFI folder and replace it with the new EFI folder.

10. Plug the USB drive into the PC and boot from USB.

11. Format the disk drive to APFS, install macOS Catalina, and restart the system.
