Overview
- A Reddit user’s discovery, documented by MacRumors, AppleInsider and Macworld on Monday, July 20, 2026, revealed a tiny Siri icon that appears next to selected text and expands into a floating popover.
- The popover presents a short set of Writing Tools—Rewrite, Proofread, “How does this sound?” and Edit with Siri—plus options to create key points or summaries and to act on content like adding contacts, composing messages or creating calendar events.
- The interface is disabled by default in macOS 27 developer beta 3 and public beta 1 but can be unlocked by testers with a private feature-flag written via Terminal, a command macOS warns may be malware.
- Hands-on testing shows the prototype is unfinished and inconsistent: some actions do not respond, the icon can take as long as ten seconds to appear, and UI behavior varies, so Apple may revise or remove it before the fall release.
- Reporters note the popover’s design mirrors the Mac’s Visual Intelligence popups, which suggests Apple could fold the feature into the system if development continues and if it proves reliable for users.
