SUMMARY:

In short, x1c5-hackintosh is very stable and is currently my daily driver. I quad boot on this machine with Linux, FreeBSD, Windows, MacOS and all provide an enjoyable experience. Overall macOS works fine on this machine.

NEEDED:

A macOS machine is needed to: Create install drives. A usb key for Opencore and a usb key for macOS Installer.

INSTALL:

Create a bootable EFI drive (format a drive as fat32). Copy over the OpenCore(EFI) files.
Create a bootable macOS install. On a Mac. Download 14.3.1. Using gibMacOS. Install the InstallAssistant.pkg. Show files on macOS Install Sonoma.app. createinstallmedia on a 32GB flashdrive.
Install Sonoma 14.3.1. May take several reboots.
Done.

UPDATE:

If you edit your opencore config.plist and change SecureBootModel from Defaults to Disabled. You will need to Reset NVRam and Clearn NVRAM afterwards. Then you can rerun the macOS Install Sonoma.app after downloading the InstallAssistant.pkg for 14.4.1 using gibMacOS and it will update to Sonoma 14.4.1. It will reboot a few times during the update. Then the second option for macOS update will disapear. You will need to change it back and update Airportitlwm.kext though. As they do not Jive. Download the latest wifi and update the three bluetooth related kexts latest bluetooth
