IoT solution based on XNU? - bit outside of Apple's gamut but I could see it. iotOS

EDIT: Eh, maybe not the copyright is quite old - perhaps more likely some internal test? Run ARM64 XNU tests on Raspberry Pis maybe? They are pretty cheap hardware with lots of ports.

This file is from 2016, apparently, so Apple has likely been using this for quite some time. It's possible that Apple found it convenient to run certain things (guesses: some IoT thing or prototyping a small embedded processor like the one inside the Lightning Digital AV Adapter) on a Raspberry Pi rather than a full-blown A-series core or other chip that is inconvenient due to {price, availability, etc.}.

iOTOS would be pretty damn interesting!

About the 2016 tag that was added to the title. While the header does say 2016, I think it's that the file wasn't made open source by Apple till this weekend.

Aside - explicit reference to Raspberry Pi here:

It's a pity that Apple let Open Darwin die off, it definitely had a potential as a nice BSD platform.

I'm still not sure of the history there. I remember one of the selling points of the early OS X was that it was a "Certified UNIX" and I remember that no one I tried to sell one too cared.

Was it just the cost of maintaining the certification? The fact that no other OS went down that route?

MacOS still is certified UNIX: https://www.opengroup.org/openbrand/register.
