Mac Pro 5,1 missing motherboard serial. Lots of certificate not generated messages in console.

Probably needs a serial to generate a certificate.

this is an audio production machine that will never go online

I think i need to put a serial in there to calm down these messages. Or disable csrutil and just delete the offending
programs, (apds, powerd, opendirectoryd, rapportd, etc)

What is best?

Correct your BootROM, recent macOS need hardware ids for a lot of things. I’ll PM with instructions.
