On June 9, 2026, Apple commenced its Worldwide Developers Conference (WWDC 2026). After the keynote speech, Apple released the inaugural beta versions of iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27, and visionOS 27 to developers. This move empowers developers to conduct early functional tests and adapt their applications to the new systems. Registered developers can participate in the testing program by accessing the 'Settings' app on their respective devices to download the corresponding beta systems. Notably, iOS 27 discontinues support for four older models, encompassing the iPhone 11 Pro Max and the iPhone SE (2nd generation). In contrast, iPadOS 27 is compatible with devices like the iPad Pro (including the latest models boasting M-series chips) and select iPad Air models equipped with M2 chips or later. macOS 27 marks a significant milestone as the first version to solely support Mac devices powered by M1 or newer Apple Silicon chips. Additionally, it introduces a fully operational Siri chatbot, leveraging Google's Gemini model. watchOS 27 introduces novel features, such as a dedicated Siri app and a dynamic app grid, whereas tvOS 27 emphasizes enhancing the Podcasts app and debuts a smart download feature.
