Release notes

Overview

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

macOS Tahoe 26 introduced Liquid Glass and broader personalization for folders, icons, widgets, Control Center, and the menu bar. Spotlight, Shortcuts, translated communication, the Phone app, and iPhone Live Activities concentrated the release on faster everyday workflows and Continuity.[1][2]

Intelligent automation and translation depend on supported hardware, languages, and regions; Apple’s live documentation remains the authority for current availability.[3][4]
