The macOS updates also include recovery image updates, system security updates, EFI updates, program updates, and a slew of other **** that Apple doesn’t disclose in the release notes. It’s not like 10.14.1 just updates the FaceTime app and adds emojis. They are always much more than the consumer level features.
[doublepost=1540928004][/doublepost]I'm signed up the Apple Security Announcements mailing list, and one just came across referencing iTunes 12.9.1, however I'm not seeing any update for iTunes on my end (Mojave 10.14.1). Also other outlets are saying HomePod 12.1 is out but it's not showing up either... Apple's CDN providers must be dragging ass today.
EDIT - it seems iTunes 12.9.1 is for Windows only. macOS version remains at 12.9.0.164.
