> No Apple developers have anything but Intel in their machines
Given that Apple almost certainly has a research lab maintaining machines running macOS on top of Apple’s own ARM chips, to watch for the inflection point where it becomes tenable to ship laptops running those chips; and thus, given that Apple already has a staff for that lab whose job is to quickly redo macOS’s uarch optimization for each new A[N] core as Apple pumps them out; it doesn’t seem like much of a stretch that those same people would do a uarch optimization pass every once in a while to answer the “can we use AMD chips on desktop yet?” question, does it?
It's true that quite a few have had AMD GPUs, and they made the more difficult PowerPC to Intel switch back in 2006 with OS X 10.4. But it would be a significant effort to change a processor partnership more than a decade old. No Apple developers have anything but Intel in their machines; it's not just an item on a BOM.
