Apple has officially entered a new chapter.John Ternus has taken over as chief executive officer of Apple, replacing Tim Cook after Cook spent 15 years leading the company.The change became effective on September 1, 2026. Tim Cook has moved into the role of executive chairman of Apple’s board, meaning he is not leaving the company completely.
For millions of people who use an iPhone, Mac, Apple Watch, AirPods and other Apple products, the change raises an obvious question.What will Apple’s new leadership mean for the products people use every day?
Tim Cook’s 15 Years at Apple
Tim Cook became Apple’s CEO in 2011 after succeeding Steve Jobs.During his time as CEO, Apple grew substantially and expanded its business beyond the iPhone.The Apple Watch, AirPods and services such as Apple Music and other subscription products became important parts of the company’s business.Cook also played a major role in Apple’s global operations and supply chain.
Apple is now one of the world’s most valuable technology companies. Reuters reported that Apple’s annual sales reached around $416 billion in 2025.
John Ternus Takes Over
John Ternus has been with Apple since 2001 and has spent much of his career working on hardware.Before becoming CEO, Ternus served as Apple’s senior vice president of Hardware Engineering.His background is different from Cook’s. Cook was strongly associated with operations and business management, while Ternus has spent much of his career working on Apple’s products and engineering teams.
Will iPhone Users Notice a Difference?
There is no reason for users to expect an immediate change to their existing iPhones.The leadership transition does not change how current devices operate.Apple’s software updates, customer services and existing products will continue to be managed by the company’s large teams.The more important changes will likely become visible over time through new products and technologies.
Apple’s AI Challenge
One of the biggest issues facing Ternus is artificial intelligence.Apple has been under pressure to keep up with companies that have moved aggressively into AI.Reuters reported that Ternus takes over Apple at a time when the company is trying to strengthen its position in the AI race.
How Apple develops AI features and integrates them into the iPhone and other products could become one of the defining parts of Ternus’s leadership.
A Major Product Event Is Coming
The leadership change is happening just before Apple’s September 9 product event.Apple is expected to introduce its next generation of products at the event, which will be the first major launch under Ternus’s leadership. Reports also suggest that Apple could enter the foldable smartphone market.That makes the event particularly important.
What Comes Next?
Apple’s change in leadership does not mean the company will suddenly become a completely different business.Ternus has worked at Apple for more than two decades and knows the company well.The bigger question is how he will guide Apple through the next phase of artificial intelligence, smartphones and new hardware.For consumers, those decisions could eventually influence what the next generation of Apple products looks like.
Final Takeaway
Tim Cook’s 15-year period as Apple CEO has officially ended.John Ternus is now responsible for leading the company while Cook continues as executive chairman.There may be no immediate difference for iPhone users, but Apple’s upcoming products and AI strategy will provide an early indication of the company’s direction under its new CEO.
