WWDC 2026: The Siri Reset That Will Define Tim Cook's Legacy

The AI reset: what's driving the overhaul

Apple's 2024 push into AI was not the seamless debut the company hoped for. A strategic course correction began in early 2025, culminating in a multi-year, billion-dollar partnership with Google announced in January 2026 to license a custom Gemini model as the engine for Apple Foundation Models . The conference tagline, “Coming Bright Up,” is reported to tease the glowing Dynamic Island interface for the new Siri .

Siri 2.0: the real centerpiece

Extensive pre-event reporting from Bloomberg, 9to5Mac, and others points to a radical Siri rebuild that transforms a basic voice command parser into a full chatbot .

A dedicated Siri app with a chatbot interface

Siri is expected to exist as a standalone app featuring an iMessage-style dark interface with persistent conversation bubbles and chat history synced across devices via iCloud . Users will be able to toggle between voice and text, and a paperclip icon will allow for file and image attachments .

Multi-step commands and screen awareness

The new Siri is reportedly capable of chaining up to 10 sequential actions across and within apps from a single prompt and can maintain conversational memory for 50 turns . It is also expected to understand what is on a user’s screen, enabling actions like sending a photo without manually identifying a specific file .

A privacy-first architecture

Apple's approach divides the labor: simple requests run on the device's Neural Engine, while complex reasoning and natural language understanding are routed to Apple's Private Cloud Compute, which runs the custom Gemini model .

Third-party extensibility

Siri will be opened to third-party AI chatbots like ChatGPT, Claude, and Gemini through an "Extensions" system in Settings . Developers will receive APIs to expose their own apps’ capabilities directly to the new assistant .

iOS 27 and macOS 27: more stability than spectacle

Software updates will be previewed for all major platforms, but the focus is on refinement.

iOS 27: a "Snow Leopard"-type release

Described as a "deep clean" rather than a visual redesign, iOS 27 prioritizes performance and stability . It will drop support for the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, and iPhone SE (2nd generation) . Other expected refinements include revamped AirPods settings, Genmoji enhancements, and Google Cast support .

macOS 27 "Mammoth" and beyond

The new macOS is expected to bring the full Siri overhaul and Apple Intelligence 2.0 to the Mac, alongside a refined "Liquid Glass 2" design language . This update will also mark the end of official support for Intel-based Macs .

Health+: the announcement that won't happen

Contrary to earlier rumors of a marquee AI health subscription, the project code-named "Mulberry" was reportedly scaled back in February 2026 following a leadership shakeup in Apple's health organization . A full standalone Health+ premium service is not expected. Instead, Apple plans to roll out individual AI health features—such as enhanced nutrition tracking and personalized wellness insights—directly into the existing Health app over time .

The bottom line

This WWDC is Apple's AI redemption moment, with the company betting its post-Cook future on a Siri that can finally compete. The narrative is as much about leadership continuity as it is about technology: Cook must prove Apple is prepared for the AI era as he passes the baton to Ternus .
