Ryzen Mac Pro - OpenCore EFI for Asus Strix X570-I

This repository provides the basic EFI folder to run macOS Catalina on an Asus ROG Strix X570-I Gaming motherboard. The default provided currently using a Ryzen 9 3950X 16 Core CPU and a Radeon VII with MacPro7,1 SMBIOS. For a short guide to using different CPU, GPU and SMBIOS see below. This is intended as a reference and to share improvements for similar build, not as an out of the box EFI to download. It is highly recommended to start with a vanilla OpenCore and following OpenCore Vanilla Guide first.

Ryzen Mac Pro build

Prozessor: AMD Ryzen 9 3950X
Cooler: Custom Water Cooling
Motherboard: Asus ROG Strix X570-I Gaming
WIFI/BT: Broadcom BCM94360NG
Memory: Kingston HyperX Predator (2x 32GB) DDR4-3600
Storage: Corsair MP600 (1000GB) M.2 NVMe PCIe 4.0
Video Card: XFX Radeon VII 16GB
Power Supply: Corsair SF600 Platinum
Case: Phanteks Enthoo Evolv Shift (Mini-ITX)

Notes

I've heavily modded the case to fit the Radeon VII with 3 120mm radiators in it. Also I've replaced the integrated Intel AX200 module with a BCM94360NG that is natively supported by macOS.

Versions

BIOS: 3406
OpenCore: 0.6.7
macOS: 11.3 Beta

ACPI

• SSDT-HPET.aml together with the first rename patch fixing IRQ conflicts
• SSDT-PLUG.aml sets plugin type
• SSDT-SBRG.aml fixing EC, RTC and IRQ conflicts
• SSDT-USBX.aml fixing USB Power
• SSDT-SBUS-MCHC.aml fixing SMBUS support (disabled by default as it breaks sleep)

The second patch is renaming the second XHC0 to XHC2. This is completely optional as the USBPorts.kext does match on the path instead of the name, but it makes easier to differentiate ports. Note: XHC0 is not renamed to XHCI since the MacPro7,1 SMBIOS does not require this, if iMacPro1,1 is to be used this would have to be fixed with an SSDT-XHC as usual.

Kexts

Besides the default kexts the following are noteworthy:

For enabling the integrated Intel Bluetooth/Wifi you can use the kexts from OpenIntelWireless. Though Bluetooth is working mostly perfect, some things like audio input (Bluetooth Mic from AirPods for example) do not work.

The AMD Power Gadget can be downloaded from https://github.com/trulyspinach/SMCAMDProcessor/releases. Other monitoring tools can also access and display this information.

The VoodooTSCSyncAMD kext is used to sync the cores and required the correct number of threads (cores * 2). Either update the Info.plist of the kext or create a new one with the VoodooTSCSync configurator.

The AGPMInjector kext is used to inject proper power management and can be created with Pavo-IM's generator and is specific to MacPro7,1 SMBIOS and the Radeon VII. It is recommended to create a custom kext.

The USBPorts kext is depending on the SMBIOS and the current controller layout in the DSDT.

Setup

BIOS settings

Everything is tested with Asus' latest BIOS 3402 Beta:

• CSM: disabled
• Above 4G decoding: enabled
• RezisableBAR: disabled
• Fast boot: disabled

Known issues

The integrated Intel Wifi is supported by itlwmx though missing support for AirDrop etc.

Microphone is not yet working through integrated audio codec.

Notes

Use at your own risk.

See branch asrock-x570-itx with the EFI for the old build.
