Apple ships iOS 27 with Siri AI overhaul

Apple released iOS 27 and macOS Golden Gate 27, featuring a revamped, AI-powered Siri alongside refinements to the "Liquid Glass" visual design. This is also the final macOS version to support Rosetta for running Intel-only apps.

Why it matters: A genuinely improved Siri is Apple's most consequential AI move yet since it reaches hundreds of millions of devices by default, unlike chatbot apps people must choose to install. Early hands-on reports suggest people are using Siri again, which matters competitively given Apple has lagged OpenAI, Google, and Anthropic on generative AI features.
