macOS 27 will feature a redesigned interface addressing criticisms of macOS Tahoe's Liquid Glass design, focusing on improved readability by adjusting shadows and transparency. Bloomberg's Mark Gurman reported these changes aim to simplify navigation and visual clarity. Safari will gain an AI-powered tab grouping tool, allowing automatic organization of browser tabs across devices. Users can opt for manual control or let the system group tabs dynamically. This update reflects Apple's effort to refine its macOS experience following user feedback on Tahoe's interface.

The redesign and tab feature stem from broader user critiques about macOS Tahoe's overly complex Liquid Glass aesthetic. Gurman noted Apple's goal is to make the interface more intuitive while maintaining its visual identity. The AI-driven tab grouping leverages Apple's ongoing push into artificial intelligence, extending beyond macOS to iOS 27 and iPadOS 27. This tool could streamline multitasking for users managing numerous open tabs, though specifics about the AI's capabilities remain limited in the leaked details.

Apple plans to unveil macOS 27 during its June 8 WWDC 2026 keynote. The first developer beta will follow immediately after, with public testing in July and a full release expected by September. These updates position macOS 27 not just as a cosmetic refresh but as a response to real user pain points. By combining design tweaks with practical AI tools, Apple aims to enhance productivity without sacrificing the macOS ecosystem's core strengths.
