Briefings
Apple released Safari 27.3 for iOS, iPadOS, and macOS, introducing vertical tabs on the left side of the screen and a new Adaptive Dark Mode feature. Users can now toggle vertical tabs via the Safari menu, and the browser offers a built-in option to adapt dark mode for websites lacking native dark theme support. The update was tested by a user who described the vertical tabs as a welcome addition to their workflow.
Key points
- Safari 27.3 introduces a vertical tab layout positioned on the left side of the screen, replacing the standard horizontal tab bar.
- Adaptive Dark Mode allows users to request a dark theme for websites that do not have one built-in, with an option to opt out.
Context
This update is significant as it adds native dark mode support for websites without a dark theme, alongside a new vertical tab layout that complements the iPhone Duo's larger display. The feature was tested by a user who found the vertical tabs to be a welcome addition to their workflow.
Limitations
The evidence is limited to a single user's experience and a single snapshot of the update. No specific dates for the feature's release or adoption are provided, and the exact number of users affected is unknown.
