# Hidden Siri AI Interface Discovered in macOS 27 Beta Try Apple's AI-powered Siri before its official release. - **Source:** [Mashable](https://brifing.si/source/3cd6d1d0-9c29-4750-8bc9-f2afefb52505) - **Published:** 2026-07-20 - **Original article:** - **On Brifing:** https://brifing.si/s/1f59c0ed-5095-4b39-9f15-588b9de66a51 ## Hidden Siri AI Interface A hidden Siri AI interface has been discovered in the macOS 27 Golden Gate beta by a Reddit user. This interface offers various AI tools through a pop-up menu when text is highlighted. Features include rewriting, proofreading, and summarization. ## Contextual Tools Siri AI can provide specific tools based on the context of the selected text. For example, highlighting a phone number shows an 'Add to contacts' option, while an address offers 'Open in Maps.' Functions like creating calendar events and tracking flights are also available. ## Why Is It Hidden? The feature remains hidden because it's unfinished. The Siri AI interface in macOS 27 developer beta 3 and public beta 1 contains bugs and non-functional options. Apple is likely refining it before an official release. ## How to Enable It Reddit users found a way to enable the interface using Terminal commands. However, this process is risky and should only be attempted by tech-savvy users. After entering the commands, a computer restart is required. ## Terminal Commands To enable the interface, users must enter 'sudo mkdir' and 'sudo defaults write' commands in Terminal. After completion, the computer needs a restart. The interface can be disabled by running the same commands with a 'false' value. ## Apple's AI Strategy Apple's efforts to reposition Siri as an AI assistant are evident with this hidden interface. The company aims to deliver a consistent AI experience across its products. Whether this feature will make it to the official release remains to be seen. ## Sources covering this story - https://mashable.com/tech/macos-27-beta-secret-siri-ai-interface — --- _Summary written by Brifing from the original reporting.
