Mac Year Missing in About this Mac

Hey guys. I am noticing a slight bug in About this Mac. The Mac's year model is missing. I have run Mac OS X Lion to OS X El Capitan (since Mac OS Snow Leopard never showed the year anyway) and it never shows the Mac's year. Now, I have seen the year number before on Lion, but then I had to replace the logic board and reinstall OS X. Strange though, I reinstalled OS X El Capitan, and About this Mac showed "MacBook" and that was it. When I ran macOS Sierra using dosdude1, it then showed MacBook (13 inch, Late 2008, Aluminum). It makes me think that pre-macOS Sierra systems can no longer connect to Apple's database to find the serial number; which would give the Mac's year.

I have had the same issue with my MacBook Air Early 2008. Of course, I went about a month with About this Mac simply saying MacBook Air. And then one day it simply showed MacBook Air Original. I ran OpenCore on the Mac to get to OS X El Capitan just to see how it ran, and About this Mac showed MacBook Air Original. Turns out OS X El Captain does not do good on the Mac, so I went back to Mac OS X Lion. Even since, the Mac has never shown the year number.

Is this an Internet issue? Apple's issue? The Mac's issue? Or even the OS's issue?

I think it's so weird that it worked fine and then randomly stopped. Any ideas?

@insympathy - Great news many, many months later. I have found the solution as to why this is not working. I have made a guide: How to Fix Year and Model in About this Mac

Serial number is generated for a specific set of hardware. Since you say you’ve replaced a motherboard- I believe system can’t manage to find that serial number value stored anywhere.

@insympathy - But the serial number does show up in About this Mac. When I punch in the serial number into Apple's website, it shows 13-inch, Late 2008, Aluminum. Plus, when I run macOS Sierra, About this Mac shows the year. And my MacBook Air which still has the original logic board still won't show the year number, even though it used to about a month ago.

But hey, it could be a serial number issue. In which case... do you have any idea how to fix something like that?

Not sure, but I have something you might try: https://support.apple.com/en-us/102550

It's an article on performing a hardware diagnostics on your Mac. On the screenshots in this manual you can clearly see a serial number is being displayed, so try running it and if you will see a serial number of your machines there - nothing to worry. Might be just a some kind of a small macOS bug. Hope that helps
