Overview

• The free update is available now via System Settings > General > Software Update, with full installer and IPSW downloads on Apple’s CDN.
• Apple’s compatibility list covers all Apple‑silicon Macs and a short list of Intel holdouts, notably the 16‑inch MacBook Pro (2019) and the 13‑inch MacBook Pro (2020, four Thunderbolt 3 ports).
• Advanced Apple Intelligence capabilities require M1 or later hardware, leaving many Intel models without on‑device AI features.
• Key additions include the Liquid Glass interface, a revamped Spotlight with direct actions and clipboard history, Live Activities from iPhone on the menu bar, a new Phone app, and new Journal and Games apps.
• Apple and third‑party guides recommend backing up with Time Machine, ensuring roughly 20GB of free space, and keeping the Mac plugged in on a reliable internet connection before upgrading.
