Apple Appoints John Ternus CEO Amid Apple Intelligence Expansion

Apple Intelligence

Apple announced a leadership change and a significant expansion of its artificial intelligence capabilities at the 2026 Worldwide Developers Conference. Tim Cook is transitioning to the role of Executive Chairman. John Ternus, previously the head of hardware engineering, is the new CEO. This change occurs as the company prepares to release iOS 27 and macOS 27, which integrate the updated Apple Intelligence framework.

The updated Apple Intelligence system introduces AI Extensions. This feature allows the operating system to access external generative models. Users can choose to connect services like Google Gemini or Anthropic Claude for tasks that require high computational power. The system processes standard requests on the device to maintain privacy. Complex queries use secure cloud-based systems. This architecture ends the previous restriction on third-party AI models within the iPhone and Mac software environments.

New Search or Ask Interface Replaces Siri

Apple is replacing the Siri brand with a system called Search or Ask. This interface uses a text-based panel instead of the traditional voice-only interaction. It is the central hub for system commands, file searches, and external AI queries. The design reflects a shift toward chat-based interactions common in modern large language models.

The AI Extensions API allows third-party developers to integrate their models directly into the OS. Apple requires these providers to follow specific data privacy protocols. A secure gateway manages the data flow to ensure external providers do not access personal information without user consent. This strategy suggests Apple is prioritizing ecosystem flexibility over proprietary model dominance.

John Ternus takes leadership as Apple moves toward an AI-centric business model. Ternus previously managed the transition to Apple Silicon hardware. His appointment concludes Tim Cook's fifteen-year tenure as CEO, which focused on supply chain efficiency and service revenue. The success of iOS 27 and the new Apple Intelligence features is the first major indicator of the company's performance under Ternus.

The AI Extensions API is available for developer testing now. Apple plans to release a public beta of the new operating systems in July 2026. The final versions of iOS 27 and macOS 27 will likely arrive in September 2026 alongside new hardware models.
