1. Siri AI: Rebuilt with Google Gemini Support

The headliner of the show was the formal rebranding and complete rewrite of Apple's assistant, now officially named Siri AI.

Following development iterations over the last two years, Apple consolidated its effort by partnering with Google to underpin its core reasoning systems. Siri AI’s reasoning, vocabulary, and generation models are now co-developed using Google Gemini models as a primary backend.

Architecture of Siri AI

• Siri AI Layer: Handles conversational, context-aware, and onscreen awareness processing.
• Apple Foundation Models: Handles speech, image, and text processing locally.
• Google Gemini Models: Serves as the co-developed server-side and local reasoning backbone.

Core Siri AI Capabilities

• Personal Context and Actions: Siri AI can search privately across your emails, text messages, calendars, and photographs. For example, you can request, "Add the photo of Bryce and Madison to our shared family album," and the system will locate and execute the task.
• Onscreen Awareness: By utilizing local screen-parsing architectures, Siri AI understands whatever is displayed on your screen. It can identify landmarks in your photos, extract dynamic details, or offer instant step-by-step navigation directions to a location featured on your display.
• The Dedicated Siri App: Apple is launching a standalone Siri AI app that maintains an end-to-end conversation history. Conversations are securely synchronized via iCloud across your iPhone, iPad, Apple Watch, and Mac.
• Spotlight Integration: In macOS 27 Golden Gate, users can type prompts directly into Spotlight. If the system detects a complex task, it routes the query to a compact Siri AI chatbot window on the desktop. Users can also right-click single or multiple files in Finder and ask Siri AI questions based on the selected files' content.

2. Apple Intelligence Expands Across Core Apps

Beyond Siri AI, Apple's broader intelligence framework has been woven directly into standard system applications.

Photos: Spatial Reframing, Clean Up, and Extend

The Photos app received three major AI-powered updates in iOS 27:

• Spatial Reframing: Leveraging spatial depth models designed for Apple Vision Pro, this tool allows users to re-render the framing of a photo after it has been taken. The model calculates shifts in perspective and generates missing visual data to present a newly framed photo.
• Clean Up: Allows users to easily erase distracting background elements from a capture.
• Extend: Uses generative models to expand the canvas around a photo's subject, generating contextually appropriate surroundings.

Safari: Text-to-Extension Generation

Apple introduced a tool called Describe an Extension in Safari. Users can type a natural language prompt—such as "Create an extension that highlights and rates recipe ingredients on this page"—and Safari is designed to generate a custom, functional extension directly inside the browser toolbar.

Safari also gains background tab monitoring, allowing the browser to silently monitor open web pages and send notifications when a status or update changes on the site.

The Passwords App & Smart Home Alerts

The default Passwords app can now automatically update compromised or weak credentials on eligible online accounts to strong, unique passwords. Meanwhile, the Home app has redesigned its alert system: instead of flooding your lock screen with consecutive push notifications, it batches smart home alerts continuously.

3. macOS 27 Golden Gate: The End of the Intel Era

Craig Federighi, Senior Vice President of Software Engineering, introduced the latest version of macOS: macOS 27 Golden Gate.

The visual presentation featured Craig driving a Volkswagen bus through Apple Park, poking fun at the company's long history of California-themed operating systems.

Dropping Intel Mac Support

As pre-announced at WWDC 2025, macOS 27 Golden Gate officially drops support for all Intel-based Macs. macOS 27 will install exclusively on Macs powered by Apple Silicon. The final Intel Macs left behind include:

• Mac Pro (2019)
• MacBook Pro (16-inch, 2019)
• MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)
• iMac (27-inch, 2020)

While Intel Macs will continue to receive security updates for the next three years, no new feature updates will be supplied.

Interface Refinements

macOS 27 focuses on cleanup and visual polish:

• Window corner radii have been slightly tightened to make the desktop feel more compact.
• Sidebars in native apps now extend to the very edge of the window frame and retain their distinct system-theme color, making it easier to identify the active window.
• A more uniform app toolbar has been added at the top of windows, making labels and headers easier to read.

4. The Liquid Glass Transparency Slider

Last year, Apple introduced Liquid Glass—a translucent design language that integrated refractive glass materials and fluid physics into UI buttons, bars, and overlays. The design drew polarized feedback, with some users criticizing its impact on readability and contrast.

At WWDC 2026, Apple addressed these concerns directly by adding a customization slider for Liquid Glass across iOS, iPadOS, and macOS.

Located in the display and accessibility settings, this slider allows users to precisely adjust transparency levels, finding their own balance between opaque, tinted backgrounds and clear, translucent glass effects.

5. Performance Gains and Quality-of-Life Upgrades

Apple claimed several substantial speed and infrastructure optimizations across iOS 27 and macOS 27:

• App Launching: Standard applications are optimized to open up to 30% faster.
• Camera Roll Indexing: Newly captured photos will index and appear in your camera roll up to 70% faster.
• AirDrop Transfers: Data transfers using AirDrop are up to 80% faster.
• File Browsing: Searching and indexing local files is up to 5x faster, utilizing a completely rebuilt CoreSearch foundation that populates Spotlight, Mail, and Photos almost immediately.
• AirPods Custom EQ: For the first time, AirPods users can customize and save a system-wide custom EQ profile directly within the iOS 27 settings.

6. Trust, Safety, and Parental Controls

A massive pillar of the WWDC keynote centered on child safety and parental controls.

Apple introduced Communication Safety tools across all operating systems. This on-device technology detects and blocks sensitive media—such as nudity, violence, or gore—from being viewed by kids and teens in Messages, Mail, AirDrop, and third-party communication tools.

Additionally, parents can configure safe app-time limits and app-access rules from their own devices, syncing to child accounts across iPhone, iPad, Apple Watch, and Mac.

7. Device Eligibility: An Inconsistent Story

While Apple extended the lifespan of older iPhones this generation, it took an aggressive approach to the Apple Watch lineup.

iOS 27 Compatibility (Highly Inclusive)

In a major surprise that defied pre-event rumors, iOS 27 will support every single device that was capable of running iOS 26. This means devices back to the iPhone 11 series (released in 2019) and the iPhone SE (second generation, 2020) will receive the update.

Note: Siri AI and other advanced Apple Intelligence processing remain restricted to the iPhone 15 Pro, iPhone 15 Pro Max, and the iPhone 16/17 series or newer.

watchOS 27 Compatibility (The Bloodbath)

In contrast, watchOS 27 drops support for six prominent watch lines. Devices running on older chipsets are cut off, making watchOS 27 compatible only with models released in 2024 and 2025.

Supported watchOS 27 Models:

• Apple Watch Series 10
• Apple Watch Series 11
• Apple Watch SE (3rd Gen)
• Apple Watch Ultra 2
• Apple Watch Ultra 3

Discontinued watchOS 27 Models (Stuck on v26):

• Apple Watch Series 6, 7, 8, and 9
• Apple Watch Ultra (1st Gen)
• Apple Watch SE (2nd Gen)

8. Regional and Bandwidth Constraints

Apple was transparent during the keynote regarding the server costs and regulatory challenges of deploying consumer AI at scale.

Daily Usage Limits & iCloud+

Because complex image generation and spatial reframing rely on high-performance cloud server farms, Apple is introducing daily bandwidth and usage limits on certain generative AI tools. Users can unlock increased access and higher daily caps by upgrading to an iCloud+ subscription plan.

EU and China Regulatory Blocks

Due to regulatory compliance challenges, Apple announced major regional limitations:

• The European Union: Siri AI will not be available at launch on iOS 27 and iPadOS 27 within the EU. However, Mac, Vision Pro, and Apple Watch users inside the EU will be able to access Siri AI when their system is set to English or another supported language.
• China: Siri AI and other Apple Intelligence features are temporarily blocked in China while Apple works through local compliance and regulatory data residency requirements.
