Chosen Solution
Late 2013 MacPro with CPU, RAM, and SSD upgrades. Not my main machine. Just realized that the serial number does not show up. Other than this, the machine runs perfectly. Apple Store offered to replace the logic board in order to be able to use their serialization tool. The logic board is the original and is otherwise fine. Any ideas on how to flash the board to reset the serial number? Or how to get the tool? Thanks.
I’d say take it into a Apple Authorized Service Provider and have them run AST on it. It should, if the serial number hasn’t been set, prompt them to serialize the unit. Otherwise, you’re likely looking at having to get your hands on the serializer tool. You’d want to locate Blank Board Serializer v 1.1.1 .
