John Ternus has officially taken over as Chief Executive Officer of Apple, beginning a new chapter for one of the world’s most valuable technology companies.
The leadership change took effect on Tuesday, September 1, 2026. Apple announced the succession in April as part of its long-term leadership plan. The company’s board unanimously approved Ternus as Cook’s successor.
Tim Cook, who became Apple CEO in August 2011 after succeeding co-founder Steve Jobs, has now moved into the role of Executive Chairman. He will remain involved with Apple and continue to support the company in areas such as engagement with policymakers.
Ternus Takes Charge After 25 Years at Apple
Ternus, 50, joined Apple in 2001. He most recently served as Senior Vice President of Hardware Engineering, where he led teams responsible for several of the company’s biggest products.
During his time in the role, Ternus worked closely on the development of the iPhone, iPad, Mac and AirPods. His extensive experience inside Apple gives the company a leader who understands its engineering culture and product strategy.
Ternus therefore represents continuity rather than a dramatic change in direction. However, his new role comes with major challenges.
AI and Innovation Await Apple’s New CEO
Apple faces increasing pressure to strengthen its position in artificial intelligence. The company must also maintain growth across its hardware and services businesses while developing new products for the next phase of its expansion.
Ternus will also need to navigate a rapidly changing smartphone market and growing competition across the technology industry.
His first major test will arrive almost immediately. Apple plans to hold its next major product launch event on September 9, just eight days after Ternus takes charge. The company is expected to unveil its latest iPhone lineup, with reports also pointing to a possible first foldable iPhone.
For Ternus, the task now goes beyond taking over from Cook. He must protect Apple’s enormous success while creating the next generation of products and technology that can define his era.
The transition marks the end of Cook’s 15-year run as CEO and the beginning of a new chapter under one of Apple’s longest-serving executives.
