This change aims to create higher consistency across the company's software platforms, affecting many factors such as icon style, menu, application, windows and system buttons.
Bloomberg said that the new design can be inspired by VisionOS (Vision Pro's mixed reality operating system) with the highlight being transparency, floating interfaces and rounded application iconography.
Apple has not made a major overhaul to its software interface since iOS 7 and macOS Big Sur.
When launched in 2013, iOS 7 marked the first major change under the leadership of former Design Director Jony Ive, while macOS Big Sur in 2020 paved the way for Apple to run the iPad app and support custom chips.
Although there are no major similar changes to iOS 19, iPadOS 19, or macOS 16, Apple is continuing to develop Apple Intelligence - a set of artificial intelligence (AI) features that have not been synchronously integrated across all applications.
Apple Intelligence is introduced with iOS 18 with a series of AI tools that support sound, image and text processing, along with a new Siri version that can operate in the application on behalf of users.
However, many features will only be rolled out after launch, especially the new Siri is not yet ready. Apple recently confirmed that this virtual assistant will officially appear "next year".
