ASUS X299 Hackintosh

Introduction

The ASUS X299 Hackintosh repo contains OpenCore EFI distributions and related files that can be used as a reference when starting or migrating your X299 Hackintosh to OpenCore. While the EFIs can be used as a starting point and should be compatible with all ASUS X299 boards, it is still highly recommended to review the OpenCore Vanilla Desktop Guide and Skylake-X section for a proper guide.

Comments

The ASUS WS X299 Sage series (WS X299 Sage, WS X299 Sage/10G, Pro WS X299 Sage II) are great motherboards with 7 PCIe slots running at 16x/8x/8x/8x/8x/8x/8x and multiple M.2/U.2 connections. The Sage/10G even includes dual 10Gb Intel X550-AT2 LAN ports that are compatible with macOS. Unfortunately the motherboards only have a few USB ports and only a single 19 Pin USB 3.0 header for internal ports. In order to connect internal USB devices such as Bluetooth or RGB Controllers there are a few options. Note that the specific cables/card listed below are examples. Just make sure the PCIe card is compatible with macOS.

• 1. USB 3.0 20 Pin Female to USB 2.0 Pin Male Adapter
  • This adapter converts the internal USB 3.0 19 pin header to a USB 2.0 9 pin.
  • Currently using this in my build with a USB 2.0 9 Pin Header 1 to 4 Extension Hub Splitter to connect Bluetooth.
• 2. USB 2.0 IDC 5 Male to USB A Male adapter
  • Uses one of the USB ports on the back of the motherboard to connect internal devices in the case. You can get two of these and remove 1 of the pins to make a "9 pin internal adapter". If the cable is too short from the back to inside the case, you can get some regular USB A extension cables.
• 3. PCIe USB 3.0 Card with Internal USB Connector
  • Inateck USB 3.0 Card
  • StarTech USB 3.1 PCIe Card
  • Can use the internal header on the card for the case USB ports or to connect internal devices.
  • NOTE: Wake from Bluetooth devices does not work with this so it's best to connect Bluetooth to one of the motherboard ports.
