Apple's 2026 operating systems will be unified and see a major visual upgrade called the Liquid Glass design language.

New touch-responsive Liquid Glass interface design "dynamically reacts" when you touch it, according to Apple.

At WWDC 2025, Apple changed how we interact with our devices with the introduction of a new user interface it calls Liquid Glass. Apple CEO Tim Cook described it this way: “Expressive. Delightful. But still instantly familiar.”
