Generate your own SMbios

Platforminfo

For setting up the SMBIOS info, we'll use CorpNewt's GenSMBIOS and ProperTree application. https://github.com/corpnewt/GenSMBIOS https://github.com/corpnewt/ProperTree

Because of the KabyLake R, we'll choose the MacBookPro14,2 SMBIOS:

Run GenSMBIOS, pick option 1 for downloading MacSerial and Option 3 for selecting out SMBIOS. This will give us an output similar to the following:

Type: MacBookPro14,2

Serial: C02WXAY2HV2N

Board Serial: C02826303CDHRPC8C

SmUUID: 88AA1336-8DF9-477A-A39F-03D016ED0809

The order is Product | Serial | Board Serial (MLB)

The Type part gets copied to Generic -> SystemProductName.

The Serial part gets copied to Generic -> SystemSerialNumber.

The Board Serial part gets copied to Generic -> MLB.

The SmUUID part gets copied toto Generic -> SystemUUID.

We set Generic -> ROM to either an Apple ROM (dumped from a real Mac), your NIC MAC address, or any random MAC address (could be just 6 random bytes, for this guide we'll use 11223300 0000. After install follow the Fixing iServices page on how to find your real MAC Address)

Reminder that you want either an invalid serial or valid serial numbers but those not in use, you want to get a message back like: "Invalid Serial" or "Purchase Date not Validated"
