So this section is for those who don’t have native NVRAM, Hardware to have incompatible native NVRAM with macOS are the Z390-300 series chipsets:

• B360
• B365
• H310
• H370
• Q370
• Z390

Outlay’s to making a NVRAM.plist file, Requires the following:

Change these settings within the config.plist:

• DisableVariableWrite: set to YES NVRAM Section
• LegacyEnable: set to YES
• LegacySchema: NVRAM variables set and injected into OpenCore and compares these variables present in nvram.plist Security Section
• ExposeSensitiveData: set to 0x3 (Which allows all data exposure)

• FwRuntimeServices.efi (Needed for sleep, wake and shutdown and other services to work correctly (Goes in the EFI/OC/Drivers Folder)
