Guides used:

Dortania’s OpenCore Install Guide.

What's working:

• iGPU with full acceleration.

• Sound.

• Ethernet

• Wifi and bluetooth. Wifi requires Heliport application to be used.

• iMessages, Facetime

• All USB ports; USB3, USB-C, USB2 (You'll need Hackintool to assign USB ports properly)

What isn’t working:

• AirPort, AirPlay, AirDrop
• DRM in Apple TV application. (Only trailers works fine)
• Sleep - To avoid problems with this issue, disable all switches in Energy Saver section of Settings - In Lock Screen, set 'Turn display off when inactive' to 'Never'

Notes:

SMBIOS info:

I set SMBIOS to iMacPro1,1.

Intel HD Graphics 630

In OpenCore config.plist, in DeviceProperties section, I added this:

PciRoot(0x0)/Pci(0x2,0x0)
layout-id                 Data         <00001259>

Fixing the ethernet connection

Both ethernet ports work fine, the main port needs the kext IntelMausi.kext the other one uses SmallTree-Intel-211-AT-PCIe-GBE.kext.

Fixing sound:

By following the guide of fixing sound, I got sound. I use the green aux output, and I choose Internal Speaker as my output device in Sound Preferences.

In OpenCore config.plist, in DeviceProperties section, I added this:

PciRoot(0x0)/Pci(0x1F,0x3)
layout-id                 Number         <21>

Wifi and Bluetooth:

I only needed to add three kexts files in the Kexts folder.

Itlwm.kext, IntelBluetoothFirmware.kext and BlueToolFixup.kext

USB Mapping

I used Hackintool to map my USB ports. Then added SSDT-EC-USBX.aml and SSDT-UIAC.aml in ACPI folder. Also USBPorts.kext (which is created by Hackintool).

SMBIOS info:

You'll need to use GenSMBIOS to get your SMBIOS information.

Getting the required files

ACPI files: Check SSDTs section in Dortania guide.

Kexts: Mark a note of the Kexts mentioned in the Kernel - Add section of config.plist file. I've added RestrictedEvents.kext to have access to the new os updates, but keep in mind you'll need to set SecureBootModel to Disabled to install them.

Picker Variant: Check the guide 'OpenCore beauty treatment' in Dortania page.

Tools and Drivers: These are taken from OpenCorePKG package.

Installing Sequoia 15.2

Note

There is a fix to get the updates listed, this is how:

You'll need the latest RestrictedEvents.kext in Kexts folder.

Also in boot-args you'll need to add revpatch=sbvmm

You'll need to set SecureBootModel to Disabled during the installtion process. You can change it back to Default, after the installtion process is complete. You have to make sure that you are using AirportItlwm.kext that is made for Sequoia 15 or later.
