In the United States, Apple is currently testing a new feature in the macOS 27 Golden Gate beta version. This feature is a hidden popover interface for Siri AI that activates when users select text. The interface, which was discovered by a Reddit user in the r/MacOSBeta community, appears as a floating icon at the top-left of the selected text. When users hover over this icon, it expands into a compact popover that provides various Writing Tools and contextual actions. The tools available include options for rewriting, proofreading, and editing with Siri, as well as creating key points and summarizing text. The contextual actions offered by the popover are tailored to the selected content. For instance, users can add contact details, compose messages or emails, create calendar events, view locations in Maps, and track flights or packages. However, it is important to note that this Siri popover feature is disabled by default in both the third developer beta and the first public beta of macOS 27. Beta testers have discovered that it can be enabled through a private feature flag, although the feature is still in development and not fully functional. To activate the popover, users can execute a specific Terminal command followed by a restart of their system. Conversely, if they wish to disable the interface, a different command can be used. Despite the excitement surrounding this new feature, users have reported inconsistent behavior from the UI, and some actions do not respond as expected. This suggests that Apple is still working on refining the underlying functionality of the Siri popover. As the release of macOS 27 Golden Gate approaches, it remains uncertain whether this feature will be included in the final version. The testing phase indicates that Apple is exploring innovative ways to enhance user interaction with Siri, particularly in the context of writing and text manipulation. The feedback from beta testers will likely play a crucial role in determining the feature's viability and performance in the upcoming release.
