Apple’s macOS 27 Golden Gate beta appears to include a hidden Siri AI interface that surfaces a lightweight pop-up menu when users highlight text.
The feature was spotted by a Reddit user in the r/MacOSBeta subreddit. According to the post, the interface bundles a set of writing and editing tools, including Rewrite, Proofread, How does this sound?, Edit with Siri, plus options to summarize selected text or turn it into bullet points.
The menu also changes based on context. Mashable says selecting a phone number can bring up Add to contacts, while highlighting an address offers Open in Maps. Other actions mentioned include creating calendar events, composing messages and emails, and tracking flights and packages.
As MacRumors noted, the feature in macOS 27 developer beta 3 and public beta 1 looks unfinished. Some options reportedly do not work properly, and others do not work at all, which likely explains why Apple has not exposed it publicly.

Mashable says Redditor pdfu shared a way to enable the interface through Terminal, but also warns users not to run terminal commands or modify OS files unless they understand the risks. Mashable says it did not test the instructions.
To turn it on, the Reddit post says beta users can enter:
''bash sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && sudo defaults write /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS -dict Enabled -bool true ''
After a restart, the interface should appear. To disable it again, users can run:
''bash sudo defaults write /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS -dict Enabled -bool false ''
It’s still unclear whether this Siri AI interface will ship in the final release of the new macOS, but the beta offers another sign that Apple is positioning Siri as a broader AI layer across its products.
