AsRock Z690 Pro RS - i7 12700K - 128GB RAM - AMD RX 6900XT - Thunderbolt HotPlug - OpenCore
AsRock Z690 Pro RS Build featuring the Latest Intel Core i7 12700K, Thunderbolt 3, and AMD RX 6900 XT using OpenCore. This Build is especially for Music Production offering multiple Thunderbolt ports supporting daisy chain, and Cinema Display for a robust workflow. This guide can be used as a reference for any 600 series Motherboard with very few changes.

As the new 600 series Motherboard is out, I decided to test it and check the performance on a Hack. The idea of this build is to utilize Thunderbolt and use it for production.
Due to the easy availability of Z690 and the number of NVMe slots that were needed, the ultimate choice was AsRock Z690 Pro RS. It's an ATX motherboard offering support for 12th Gen. CPUs. PCIe 4.0 supports a faster data transfer rate. Along with all these, the motherboard supports 3x PCIe 4.0 NVMe and built-in WiFi. This can be a good choice for users needing 2.5Gb/s LAN.
On this Motherboard, the Audio Codec is not so great, offering ALC897.
|Thunderbolt 3||YES, with full HotPlug|
|Thunderbolt Dock||YES, with full HotPlug|
|eGPU||YES, with full HotPlug|
|USB 2.0, 3.0, 3.1 and USB Type-C Ports||YES|
Everything works like a charm.
Bootable Media Creation
To create Bootable USB for macOS Big Sur, follow the steps below.
1. Download macOS Big Sur from App Store.
2. Plug USB to your system.
3. Open Disk Utility and erase the USB Flash Drive with following parameters
4. Close Disk Utility.
5. Open Terminal and type:
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/USB
7. Press (Y) to confirm and then press enter key and it will start to erase the disk and will create macOS Bootable USB.
Once the process completes, close the terminal. The USB Flash Drive will be renamed as Install macOS Big Sur
- At this point, the bootable USB can be only used to boot Mac only. In order to boot the computer using the USB, follow the steps below.
To prepare OpenCore boot loader, you need to download OpenCore.
Download the Release folder followed by the release version.
When extracting, you'll get 4 folders which has been listed below.
|Docs||Contains documentation, change log, a sample config.plist, and ACPI Samples for OpenCore.|
|IA32||Contains OpenCore EFI, 32-bit OpenCore Boot Loader.|
|Utilities||Contains several utilities.|
|X64||Contains OpenCore EFI, 64-bit OpenCore Boot Loader.|
1. Copy X64 to your working directory and follow the steps below
Adding Required SSDTs
SSDTs are mandatory which allows several important fixes and is required to boot the system.
2. From the Docs/Acpi Samples/Binaries directory, copy the above SSDTs to EFI/OC/ACPI.
Adding Required Drivers
Drivers are mandatory which allows several important function and is required to boot the system.
2. From the EFI/OC directory, just keep the above drivers and delete rest of the drivers.
- All the drivers can be found at: X64/EFI/OC/Drivers
Adding Required Kexts
In order to boot into the installation, you need to add the necessary kexts. Follow the steps below to place the necessary kexts.
1. Download the above kexts.
2. Extract the kexts from the RELEASE folder.
3. Copy the kexts to: /EFI/OC/Kexts
- Do not download the project files. The pre-built binaries/downloads are available in the README.md section. Make sure you read it carefully.
- Download the latest version for better support.
- Use the kext from RELEASE folder and RELEASE.zip file.
- Do not place unnecessary kexts here. It might prevent booting the installer.
- Only use basic kexts which is required to boot off the installer. You can install the rest required kexts at the time of post-installation.
- The VirtualSMC package includes Battery and Sensors plugins (SMCBatteryManager.kext, SMCDellSensors.kext, SMCLightSensor.kext, SMCProcessor.kext, and SMCSuperIO.kext). You do not need these kexts for booting the installer.

Turn on your system.
3. Boot to Boot Menu using F12
4. Select your USB Flash Drive with the UEFI prefix and press enter to boot.
5. When at OpenCore menu, select ResetNVRAM and boot from it.
6. Repeat step no. 5.
7. When at OpenCore menu, boot using Install macOS Big Sur. It will take couple of minutes to boot into installer screen. Once you reach the installer, select your preferred language and continue.
8. On top, click on Utilities and then select Disk Utility.
9. When at Disk Utility, click on View and select Show all Devices.
10. Select your target SSD. Do not select the partition
11. Click on Erase button and erase the drive with following parameters.

12. Close Disk Utility.
13. Select Install macOS and continue with the options.
14. Select Macintosh HD and click on Install.
This will take a couple of minutes and will restart at "Less than a minute is remaining". Upon completion, the system will automatically restart. The System will restart to complete the installation. Here ends the first phase of the installation.
After installation, boot it using USB, but this time select Macintosh HD.
The first boot may be slower as the caches are not built yet. Once the caches are built, it will boot normally.
When you're at the welcome screen, continue with the basics options such as Keyboard setup, Network, Computer Account, and Privacy settings.
Now the installation is complete, but the drive isn't bootable yet. You need to complete the Post Installation
Now, configuring the Post Installation. There is not much to do for the post-installation except configuring Thunderbolt 3 Hotplug and the boot from the system drive. Everything rest is fully functional.
Thunderbolt 3 Hotplug
As of now, the Thunderbolt already works with the exception of HotPlug. To implement the Hotplug, follow the steps below.
1. Open IOReg and find the Thunderbolt Node. For PCIe Slot #4, the address is PC00.RP21.PXSX
