GoKawiilApple's iOS 27.3 beta adds Vertical Tabs and Adaptive Dark Mode to Safari
Apple has released the first developer betas of iOS 27.3, iPadOS 27.3, and macOS 27.3, introducing a Vertical Tabs layout for Safari alongside an Adaptive Dark Mode feature that generates dark versions of sites lacking native support. The update also expands Siri's ability to directly manage tabs, including moving, sorting, and closing them.
GoKawiil's interpretation of the reporting above, not reported fact.
The move brings Safari in line with browser features like vertical tab bars that Arc popularized before The Browser Company discontinued it, suggesting Apple may be absorbing ideas from browsers exiting the market. The Siri tab-management addition points toward Apple's broader push to give its AI assistant more direct control over on-screen content, with the company noting further expansion of Siri's site-awareness is planned.
- Safari gains an optional Vertical Tabs layout across iOS, iPadOS, and macOS 27.3 betas.
- Adaptive Dark Mode auto-generates dark styling for websites that don't natively support it.
- Siri can now directly move, sort, organize, and close Safari tabs, with more on-screen awareness planned.
