Apple Intelligence, the suite of generative-AI features introduced across the first developer betas of iOS 26, iPadOS 26 and macOS Tahoe, has been unavailable for many users since 19 June. Developers report that the assistant is stuck in a perpetual update loop, reverting to the legacy Siri animation and disabling on-device tools such as Image Playground, Visual Intelligence and Writing Tools. The disruption also affects the Foundation Models framework that third-party developers use, as well as the ChatGPT integration in the Xcode 26 beta. Specialist sites MacRumors and AppleInsider attribute the outage to a recent backend change pushed by Apple, though the company has not confirmed the cause. Apple’s public system-status dashboard lists no problems and lacks a dedicated entry for Apple Intelligence. As the models are largely stored on devices but receive frequent over-the-air updates, developers speculate that a failed update is preventing the software from loading correctly. Apple has not responded to requests for comment. Because the issue appears limited to pre-release software, analysts expect a server-side fix rather than an operating-system patch once the underlying fault is identified.
