It is suggested that a different SMSBios is used instead. Please also ensure that you have setup your bootable drive

Follow these instructions to change SMSBios:

1. Download ProperTree and GenSMSBIOS
2. Open the config.plist with ProperTree and use GenSMSBIOS to generate a the SMSBIOS data

   • Pick option 1 for downloading MacSerial and option 3 and enter iMac19,1.

     You should get an output similar to the following:

     Type:         iMac19,1
     Serial:       CXXXXXXXXXXX
     Board Serial: CXXXXXXXXXXXXXXXX
     SmUUID:       XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

   • In the config.plist, map the above output to the following values

     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 to Generic → SystemUUID.
