PCI
Device configurations are provided to macOS through dedicated buffers for setting PCI device properties, such as Intel buffer frame patches, sound card Layout ID, etc. Of course, the ID of the sound card can also be added directly in the form of alcid = xx through the boot entry.
Finding Device Addresses¶
Hardware addresses of different devices are different. You can use Hackintool to view specific address information:
Or you can also use OCC directly to identify and add device address information:
The effect after adding is as follows:
Of course, there are still some missing device properties, which require us to manually supplement them.

AMD Desktop Platform¶
Since AMD CPUs do not have integrated graphics, these platforms do not require special settings. You only need to add and improve sound card information. Of course, you can also directly add it through the boot entry. During the early debugging process, I suggest that you add it in the form of alcid = xx through the boot entry:
- PciRoot(0x0)/Pci(0x1b,0x0)
- This device path is subject to the actual situation and may have errors. Hackintool can be used to obtain the specific device path.
- layout - id
- AppleALC audio injection. For the complete ALC ID, refer to: AppleALC Supported Device List.
