Apple is entering a new era as John Ternus takes over as chief executive, succeeding Tim Cook after Cook’s 15-year tenure at the helm of the world’s most valuable technology companies.
Ternus officially becomes CEO on September 1, 2026, following a succession plan unanimously approved by Apple’s board. Cook will remain closely involved with the company as executive chairman, while Ternus joins the board.
The leadership change comes at a crucial moment for Apple. While Cook leaves behind a company that has grown enormously in value, revenue and services, Apple faces increasing pressure to demonstrate that it can compete with rivals in artificial intelligence.
Who is John Ternus?
Ternus is a veteran Apple engineer who has spent almost his entire career at the company. He joined Apple in 2001 after studying mechanical engineering at the University of Pennsylvania and later rose through the hardware organisation.
He became Apple’s senior vice president of Hardware Engineering in 2021. During his career, he has been involved with major Apple products, including the iPhone, iPad, Mac, Apple Watch and AirPods.
His appointment represents a significant choice for Apple: rather than bringing in an outsider to shake up the company, Apple has handed the world’s most important corporate job to an engineer who understands its products and culture from the inside.
Cook described Ternus as having “the mind of an engineer” and “the soul of an innovator”, saying he is the right person to lead Apple into the future.
AI will be one of Ternus’s biggest tests
Ternus takes over at a time when Apple is under pressure to catch up with competitors in AI.
Companies including Google, Microsoft, Meta and OpenAI have invested heavily in generative AI and AI-powered products. Apple, meanwhile, has faced criticism over the pace of its AI development, particularly surrounding Siri and its broader Apple Intelligence strategy.
That makes AI one of the most important challenges facing the new CEO.
Ternus will have to determine how Apple can turn its enormous installed base of devices into an advantage in the AI race while maintaining the company’s traditional emphasis on privacy, tightly integrated hardware and software, and premium products.
A major test of Apple’s product strategy
Ternus is also expected to face pressure to deliver the next generation of products capable of creating the kind of excitement associated with Apple’s biggest successes.
Although Cook’s tenure produced major successes such as the Apple Watch, AirPods and Apple Silicon, Apple has also faced criticism over the lack of a new breakthrough product category on the scale of the iPhone.
The Vision Pro, for example, was launched with enormous expectations but struggled to become a mainstream consumer product because of its high price and other limitations.
Ternus’s background in hardware could therefore prove important as Apple looks for its next major product breakthrough.
Cook leaves behind a transformed Apple
Cook became CEO in 2011, succeeding Apple’s co-founder Steve Jobs shortly before Jobs died.
Unlike Jobs, Cook was known primarily as an operations and supply-chain expert. Under his leadership, however, Apple expanded dramatically.
Apple’s services business grew into a major source of revenue, while products such as the Apple Watch and AirPods created important new categories. Cook also oversaw Apple’s transition away from Intel processors to its own Apple Silicon chips.
Apple’s market value also increased enormously during his tenure.
Cook is not leaving Apple completely. As executive chairman, he will continue working with the company and will remain involved in areas including engagement with policymakers around the world.
The timing could hardly be more important
Ternus’s first major public test is already approaching.
Apple has scheduled its next major iPhone event for September 9, just days after Ternus officially becomes CEO. The company is expected to unveil its next generation of iPhones, with widespread expectations that Apple could finally enter the foldable-phone market.
The event could therefore provide an early indication of the direction Ternus intends to take Apple.
At the same time, Apple is continuing to develop hardware aimed at the AI era. The company recently unveiled updated Mac mini and Mac Studio computers powered by newer chips designed to deliver significantly stronger AI performance.
What comes next
Ternus inherits a company that is financially powerful but facing significant technological and competitive challenges.
His task will be to preserve the strengths that made Apple successful under Cook while pushing the company harder in areas where competitors have moved ahead.
The central question is whether Ternus can turn Apple’s enormous hardware ecosystem into a decisive advantage in the AI era — while also producing the next generation of products that consumers genuinely want.
For Apple, the change is more than simply a new name in the CEO’s office. It marks the beginning of a new chapter, with AI, innovation and the search for Apple’s next breakthrough product likely to define Ternus’s leadership.
