> The XNU kernel runs on a variety of platforms
This is fascinating, would love to know where it’s used! (Besides macOS)
It's used in iOS as well. iOS runs in some unexpected places, like for example Studio Display. Also, the Apple Lightning Digital AV Adapter runs Darwin (because RTKit didn't exist yet).
All of Apple's platforms.
I believe it means Apple's other hardware platforms (phones, tablets, smart TVs, VR headsets, smartwatches)
