Introduction
Platform information consists of several identification fields generated or filled manually to be compatible with macOS services. The base part of the configuration may be obtained from AppleModels, which itself generates a set of interfaces based on a database in YAML format. These fields are written to three destinations:
Most of the fields specify the overrides in SMBIOS, and their field names conform to EDK2 SmBios.h header file. However, several important fields reside in Data Hub and NVRAM. Some of the values can be found in more than one field and/or destination, so there are two ways to control their update process: manual, where all the values are specified (the default), and semi-automatic, where (Automatic) only certain values are specified, and later used for system configuration.
The dmidecode utility can be used to inspect SMBIOS contents and a version with macOS specific enhancements can be downloaded from Acidanthera/dmidecode.
