Also, if APFS started with High Sierra, I guess I can start with that and let it absorb my apps, etc. from Sierra when I update

High Sierra can READ an APFS volume, it cannot format or install on an APFS volume. You have to go all the way to Mojave or Catalina.


If we knew what it was we were doing, it wouldn't be called research, would it?
