macOS 27: new Siri takes on AI productivity apps

The macOS 27 update brings the new Siri AI to the desktop, offering system-wide contextual awareness and visual intelligence tools. Users can now query information based on screen content, specific window selections, and local file data.
Why it matters
It demonstrates how AI assistants are evolving from simple voice commands to complex productivity tools that can interact with and analyze a user's entire digital workspace.
The two most noticeable things about macOS 27 Golden Gate are the newly updated Siri AI and the design changes that make windows and icons more consistent. Siri AI offers the same features and capabilities as on iOS 27, but the Mac gives it access to different context — and new ways to be useful.

Apps like Highlight , Caddy , and Littlebird can also look at your current window, then use that information as context for your queries.
