Asrock Z690 Extreme + 12700K + Rx580

[guindillas]

Hardware:

• Motherboard: Asrock Z690 Extreme
• CPU: Intel 12700K
• GPU: AMD Radeon RX580 4Gb
• Optional: Fenvi BCM94360NG WiFi/BT NGFF M.2 Key A/E Module
• RAM: G.Skill Trident Z Neo DDR4 3600 16GB
• SSD: WD Black SN850 500GB SSD NVMe M.2
• Cooler: Noctua NH-D15 chromax.black
• Power Supply: EVGA SuperNOVA 850 G5, 80 Plus Gold 850W

First Steps:

• Update BIOS to 6.03 Version.
• Load UEFI defaults in BIOS, and change this values:
  • OC Tweaker > DRAM Configuration > Load XMP Setting > XMP 2.0 Profile 1
  • Advanced > USB Configuration > XHCI Hand-off > Enabled
  • Secure Boot > Disabled
• Create the USB install media (not the scope of this post)
• Add the Platform info for ImacPro1,1 through Opencore Configurator or PlistEditor.
• Press F11 at startup an select the USB (For an easy installation you can enter BIOS (Supr key) and select USB to load at first position on UEFI startup)
• Select install Macos Monterrey, follow the installation process.

USB Map:

HS14 is for the BCM3460NG M2 Key, for Wifi & Bluetooth, in case you use this you will have to unmount the MB cover to plug the antenas (not included with this bundle), also if you use M2_2 port you will lost one SATA port (SATA3_7 more info on the manual), but you'll still have 7 more.

HS02 & HS03 are only type 2 because are going to be used only for the mouse and keyboard. And 9 USB conectors are ready to work in total, trough the HS08/SS08 an ASM 107x device are two.

HS13 is for the LED control, in case you use activate it in USB map, the light is fixed in one colour. So is best for its work to be forgotten by MacOS.

In case you want to use a FENVI T919 PCI Card, you can add, changing HS11 for the right port you plug the Bluetooth cord:

<key>HS11</key>
                    <dict>
                        <key>UsbConnector</key>
                        <integer>255</integer>
                        <key>name</key>
                        <string>HS11</string>
                        <key>port</key>
                        <data>
                        CwAAAA==
                        </data>
                    </dict>

Benchmarks:

Not bad, mostly the same in Windows 11:

This is based on the help of many people from the forum, in special thanks to @CaseySJ @bootmacos @miliuco @Edhawk & @etorix

Tech advise:
Alcid=7 number 1 also works but there are issues with headphones
Last Opencore Version = 0.8.1

Hello, i've use your EFI folder..but it wont boot, its run on the start,shoe apple logo then black sreen..canyou help me?
I have same board but CPU is i5 12600k and graphic card 6800xt..Thnx

First of all, congrats for being brave to try.

In order to adapt the EFI for a different software, you should make a little changes. One is for RX 6800 XT, that has to use agdpmod=pikera in use, so remove only the symbol #.

You should go to System preferences / sound / output /
