Overview

• The global rollout is underway for compatible Macs, delivering a system‑wide Liquid Glass redesign with translucent UI elements and expanded personalization.
• Spotlight gains quick actions, deeper Shortcuts integration, and a time‑limited clipboard history that turns the search bar into a workflow hub.
• Mac–iPhone continuity deepens with a dedicated Phone app on Mac and Live Activities in the menu bar that can hand off to iPhone Mirroring.
• New first‑party apps such as Journal and Games expand macOS tools, while customizable Control Center, menu bar, and desktop widgets improve day‑to‑day control.
• Reviewers report a generally stable experience with some day‑one bugs and third‑party app gaps; Apple advises backing up before upgrading, and some features require recent Apple Silicon models or have regional limits.
