Apple is quietly overhauling the Mail app in the latest macOS 27 Golden Gate beta, shifting the focus entirely toward Apple Intelligence. A hidden feature flag in Beta 4 reveals a redesigned compose window where traditional formatting tools are pushed aside to make room for a prominent "Write with Siri" interface. The update signals a major shift in how Apple expects users to draft emails on the Mac.
As discovered by MacRumors forum member "mactracker" - who recently uncovered a hidden Siri voice pad interface - the new formatting bar collapses classic text controls to the right edge of the composer. Once a user selects the Siri prompt and begins typing, these traditional controls vanish completely. The redesign also introduces the ability to preview contextual Smart Reply suggestions by hovering over them before insertion, a significant usability upgrade over the previous in-line design.
When a suggested composition is selected, the formatting bar dynamically updates to display "Edit with Siri," "Proofread," and "Rewrite" options. It also includes a "How does this sound?" prompt, keeping the traditional formatting controls minimized to prioritize AI-driven text generation.
Beta Implementation and Release Timeline
The new formatting bar is not enabled by default and remains hidden behind an internal feature flag, meaning most beta testers will not see it. The implementation is currently buggy and clearly a work in progress. In Beta 4, the redesign only triggers when replying to an existing message; composing a fresh email still brings up the legacy formatting bar.
macOS 27 Golden Gate is expected to launch officially in September. The operating system update will arrive alongside the highly anticipated iPhone 18 Pro models and Apple's first foldable iPhone, further expanding the reach of the company's contextually aware AI features.
Other Notable Siri AI Developments
- EU Regulatory Talks: Apple CEO Tim Cook recently held constructive discussions with EU tech chief Henna Virkkunen regarding the launch of Siri AI within the bloc, aiming to ensure compliance with regional digital regulations.
- watchOS 27 Beta 3: Siri AI and the dedicated Siri app are now live for Apple Watch users. The app is prominently featured in the center of the Dynamic App Grid when pressing the Digital Crown.
- Class Action Lawsuit: A California court recently held a preliminary approval hearing for a $250 million settlement regarding Siri AI's delayed launch. Eligible iPhone owners could receive payouts of up to $95, though a final ruling is still months away.
The Aggressive Push for AI Ubiquity
Apple is clearly prioritizing AI generation over manual interaction across its entire ecosystem. By hiding traditional text formatting in macOS 27 behind a collapsing menu and putting Siri AI front and center, Apple is conditioning users to let the system handle the heavy lifting of communication. This UI paradigm shift proves that Apple Intelligence is not just an optional tool, but the new default standard for user input.
Combined with the rapid expansion into watchOS 27 and Tim Cook's direct negotiations with EU regulators, it is evident that Siri AI is the foundational interface for Apple's next generation of hardware, including the upcoming foldable iPhone. Furthermore, the $250 million settlement highlights the immense financial and legal pressure Apple faces to deliver these promised AI capabilities without any further delays.
