Apple has a new chief executive. John Ternus officially took over as CEO on September 1, ending Tim Cook's 15-year run in the top job and completing Apple's first leadership handoff at that level since Steve Jobs stepped aside in 2011.
The move was announced by Apple in April, but today is when it becomes real. Cook is not leaving the company. He has moved into the role of executive chairman, while Ternus has joined Apple's board and now runs the business day to day.
Ternus has spent more than 25 years at Apple and built his reputation on the hardware side of the company. He joined Apple's product design team in 2001, rose to senior vice president of Hardware Engineering and has overseen work across iPhone, Mac, iPad, Apple Watch and AirPods.
That background matters because the next phase of Apple is arriving with unusually high expectations. The company is preparing for its September 9 product event, which will be the first major hardware launch under Ternus as CEO. It also comes as Apple faces pressure to move faster in artificial intelligence while continuing to defend the strength of the iPhone ecosystem.
Cook leaves the CEO role with Apple dramatically larger than when he inherited it. Reuters notes that during his tenure the company grew from roughly $350 billion in market value to around $4.5 trillion, while revenue and profit expanded sharply through the rise of services, wearables and a far larger installed base of devices.
The transition is also landing as several other senior Apple roles change hands. That makes Ternus's first months more important than a ceremonial CEO swap. He is taking over a company that remains enormously profitable, but one that is also being asked to prove it can define the next computing shift rather than simply protect the last one.
Search interest and discussion around Cook, Ternus and Apple's leadership change have been climbing as the handoff approached, with the story repeating across Apple communities on Reddit and spreading widely on X. That chatter is useful as a signal of attention, but the core facts here come directly from Apple and current reporting.
The first real public test comes quickly. On September 9, Ternus is expected to front Apple's next major product event as CEO. For a company that has had only three chief executives in nearly three decades, that stage will carry more weight than a normal iPhone launch.
