Decode MacBook assembly date from system report file? My task is to create a simple database containing information about the MacBooks my company owns. In order not to do it manually, I decided to ask everyone using a Mac to send me a system report file in the .spx format, then I've built a simple parser to extract basic info from these files. I've been able to extract CPU model and freqency, RAM size, etc.

One thing I've been unable to find the assembly date of the particular unit.I've tried 'assembly','manufacturer', 'date' and several others, but to no avail. Is this contained in the system report file?
Sign up to be a Self Servicing Account with Apple and you can look up machine PO date by serial number using their global service exchange API.

That is far more reliable than trying to reverse engineer batches of serial numbers or internal components. You can also look into build details and get technical manuals / diagnostics - so this effort to get registered will pay dividends far more than a quick script.

If you really only need a quick script or don't meet the requirements for a GSX account, I would start here:

The date isn't in the files you collected, but the serial number is which is likely the closest proxy to a build date you have at hand.
