OpenCore: 'board-id' is wrong, says Macbook10,1 should be iMac13,2. Where is it pulling this info from?

I setup OpenCore according to the Vanilla Guide but have been having issues, specifically can't get into recovery partition.

I ran ssdtPRGen to get a SSDT-PR, but encountered and error:

Error: board-id [Mac-EE2EBD4B90B839A8] not supported by Ivy Bridge – check SMBIOS data / use the -target option 

That board ID is for a MacBook10,1, and I've specified iMac13,2 in the OC config. Next I ran dmidecode and found this mess:

# dmidecode 3.2b Scanning I/O Registry for entry point. SMBIOS 3.2 present. 54 structures occupying 2353 bytes. Table at 0xD9134000.

In my OC config I have this setup in the PlatformInfo section:

Automatic:true UpdateDataHub:true UpdateNVRAM:true UpdateSMBIOS:true UpdateSMBIOSMode:create 

So where is this info being generated from? How can I correct it to see if it will stop MacOS from freaking out? Thanks
