Announced at WWDC26, iOS 27 will support switching between two iPhone devices with the same phone number.

The feature will be called iPhone Handoff. Here's a demo of the setup.

Apple tested the Himalayan Peaks aerial as a Setup Assistant backdrop in tvOS 27 beta 3.

The aerial file appeared in a new SetupBackground app that only shipped in beta 3, and was later removed in beta 4.

This landscape aerial is already available in current tvOS versions.

iOS 27 Beta 7 updates the splash intro video for Siri AI.

Here's your first look at the new Siri app on tvOS 27.

In macOS 27, you can swap Siri's model with a third-party Inference Provider extension. Here's Siri AI running on GPT-5.6.

In macOS 27, when using "Hey Siri," Siri can add your request to the previous conversation thread, even after you dismiss the Siri window.

By default, you get 7 seconds to invoke Siri and continue the chat, but you can change the timeout:

defaults write com.apple.campo sessionResumptionTimeout 7

You can make the window narrower than the default too, or adjust the sidebar to get even more space. Some more dynamically built pages already take advantage of the extra space.

A new feature in Safari 27 will let you search for text in video captions. Safari will then seek the video to the moment the matching caption appears.

To try it, enable 'Show features for web developers' under Safari Settings > Advanced. Then, enable the Find in Video flag in the Feature Flags tab.

macOS 27 Beta 5 adds a new feature that lets keyboard focus move from the active app's menus to controls on the right side of the Menu Bar using the Left/Right arrow or Tab keys. It's currently disabled by default.

Apple left a full "Pocket Tuning" panel for scroll edge effects in Beta 5

macOS 27 Beta 5 includes a new "Pocket Tuning Window" that can change the scroll edge effect in real time on supported apps. You can tune both light and dark mode effects, and can really make the scroll edge effect disappear.

New iOS and macOS betas incoming 👀

Last night, Apple published Expressive Voice assets for all 7 American voices and 4 British Siri voices.

It also published a new version of its base AI model, required for the new voices.

But the server isn't serving any of it to current builds.

Under the hood, my Claude extension implements Apple’s internal AgentIntent and receives an IntentPrompt containing the user’s request and context.

Because extensions are sandboxed, it forwards requests over localhost to a companion LaunchAgent. (6/9)

Siri Extensions can’t directly access data or invoke App Intents.

When system interaction is required, such as setting a reminder, Claude can hand the request back to Siri to complete it. (5/9)

In some cases, third-party extensions can be more powerful than Siri AI.

For example, Siri can’t create files, but Claude can easily return a CSV file when asked. (4/9)
