I feel like I've seen that font before, on non-Apple electronic products, where it was used for similar serialisation and part numbering purposes. It actually looks like a monospace version of http://www.identifont.com/find?font=code&q=Go

I wonder if Apple actually designed this font, or just asked for permission and extracted it from the built-in font of some industrial printing machine.

That font is extremely different from the one Apple is using. Compare the Q and K for the biggest differences that wouldn't be effected by 'monspacifying' it.
