Apple previewed a slick new software design and powerful software updates, including new features coming to its next-generation operating systems across devices that will receive a unified version 26. The new design features a new material called Liquid Glass, which creates a translucent effect similar to water that sits atop the display, refracting content below it and allowing colors to flow through. The company says this will bring greater focus to content, deliver a new level of quality to controls and keep users more attuned to what’s happening on screen. The new design extends across Apple’s entire device ecosystem, including iOS 26, iPadOS 26, macOS Ventura 26, watchOS 26 and tvOS 26. The company said the idea was to “harmonize” the user experience across all devices so they could expect every device to look and feel the same. It will affect buttons, switches, sliders, text and media in the user interface and shift dynamically according to user needs. Controls, toolbars and navigation within apps have been redesigned with rounded corners and they “float above” content so that they stay out of the way and avoid interrupting content. They also shift into thoughtful groupings, allowing users to find the controls they need. The Preview app, which originally comes from macOS, is coming to iPadOS 26. Preview is a dedicated app for creating a quick sketch, as well as viewing, editing and marking up PDFs and images with Apple Pencil or by touch.
