A design overhaul is only as good as its usability, and Apple’s Liquid Glass interface has been polarising since its debut in iOS 26. Now, with iOS 26.1, macOS 26.1, and iPadOS 26.1, Apple is giving users a critical choice: keep the original crystal-clear translucency or switch to a more readable, higher-contrast Tinted mode. Accessible via Settings > Display & Brightness > Liquid Glass, the Clear option preserves the glassy, layered aesthetic, while Tinted increases opacity to reduce visual noise and improve legibility in elements like Notification Centre and navigation bars. This adjustment doesn’t disable the design language; it refines it, addressing feedback from users who found the original implementation aesthetically pleasing but functionally challenging.
Liquid Glass represents Apple’s most significant UI shift since the flat design introduced in 2013, and the new control reflects a broader trend in Apple’s interface evolution: balancing visual sophistication with accessibility. The company has also extended customisation to the Home Screen, allowing Clear or Tinted icon styles, and provided alternative adjustments through Accessibility > Display & Text Size > Reduce Transparency. These refinements show Apple’s responsiveness to user experience concerns while maintaining the underlying design philosophy.
On iPadOS 26.1, productivity gains take centre stage with the reintroduction of Slide Over, a multitasking staple first introduced in iOS 9. Integrated into the new windowing system, Slide Over lets users summon a single app over existing windows, move it off-screen, and bring it back instantly. The updated version adds vertical resizing previously limited to horizontal, while sacrificing the ability to stack multiple apps. For developers and power users, this means faster context switching without sacrificing workspace, a capability especially valuable for workflows involving communication apps like Slack or reference tools alongside primary workspaces. The feature’s activation via the green window control button or keyboard shortcut (Globe + ) makes it more fluid in daily use, aligning with Apple’s ongoing push toward desktop-like multitasking on iPad.
Audio technology also sees a notable upgrade. FaceTime now delivers improved sound quality under low-bandwidth conditions, a change likely driven by enhancements in adaptive audio compression algorithms. By dynamically adjusting bitrates and leveraging modern codecs optimised for speech intelligibility, Apple can preserve clarity even when network throughput drops. This is particularly relevant for mobile users in areas with unstable connectivity, ensuring conversations remain intelligible without excessive latency.
The update also touches Apple Intelligence, Apple’s on-device AI framework, with expanded language support including Danish, Dutch, Norwegian, Portuguese (Portugal), Swedish, Turkish, Chinese (Traditional), and Vietnamese. While the much-anticipated “more personal Siri” remains slated for next year, these language additions broaden the accessibility of machine learning-driven features such as contextual suggestions and natural language understanding. For developers, this signals Apple’s continued investment in multilingual model training and inference optimisation, likely leveraging neural network architectures tuned for low-power, on-device processing.
Other refinements enhance control and reduce friction in everyday interactions. iOS 26.1 introduces a toggle to disable the Lock Screen swipe-to-camera gesture, preventing accidental activations, and modifies alarm dismissal with a Slide to Stop bar to reduce unintended silencing. Apple Music gains a swipe gesture for track changes and extends AutoMix transitions to AirPlay 2-compatible speakers, bringing DJ-style crossfades to more playback scenarios.
From a systems engineering perspective, these changes reflect Apple’s iterative approach: deploy a bold design shift, gather telemetry and user feedback, then fine-tune with targeted adjustments that preserve the vision while improving ergonomics and performance. Liquid Glass translucency control, Slide Over’s return, and adaptive audio improvements all fit this pattern, demonstrating how interface design, multitasking architecture, and signal processing can converge to refine the user experience without sacrificing innovation.
