Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

Release overview

The existing local macOS 12.0 record represents the public launch of macOS Monterey on October 25, 2021. Apple shipped and documented that public release as macOS 12.0.1, with FaceTime audio and video improvements, AirPlay to Mac, Live Text and Visual Look Up, Focus, richer Notes and Safari organization, and Shortcuts.[1][2]

Evidence boundary

This bundle preserves the audited local 12.0 route instead of creating or renaming a version record. Apple's launch article marked SharePlay and Universal Control as later arrivals, so neither is attributed to this public event. Enterprise and security details are taken from Apple's 12.0.1-labeled records.[3][4][5]
