I'm looking at buying a used Mac Pro. However, I want to know what I'm really buying as the serial number he provided does match the processor configuration in the About This Mac:
EveryMac says this is what the machine is according to its serial number:
The 2.4 GHz 6-Core configuration wasn't released until 2012 according to EveryMac:
So my question is, am I buying a 2009 Mac Pro, originally shipped with an "Eight Core" main board, but has been upgraded to a 2012 2x 6-Core main board?
If so, will I need to upgrade the firmware to match the new board?
