Apple clarifies security update policy: only the latest OSes are fully patched

Earlier this week, Apple released a document clarifying its terminology and policies around software upgrades and updates. Most of the information in the document isn't new, but the company did provide one clarification about its update policy that it hadn't made explicit before: Despite providing security updates for multiple versions of macOS and iOS at any given time, Apple says that only devices running the most recent major operating system versions should expect to be fully protected.

I mean, this seems like typical for Apple, but the vagueness of it seems problematic. If I'm managing a large fleet of devices, I would definitely prefer the more detailed, structured, documented, and defined update and patching policies of professional Linux vendors or Microsoft.
