John Ternus is a longtime Apple executive and one of the company's most senior hardware leaders. He is set to take over as Apple CEO on September 1, 2026, succeeding Tim Cook. Cook will become Apple's executive chairman.
Who Is John Ternus?
Ternus joined Apple's Product Design team in 2001 and has spent nearly his entire professional career at the company. He became Vice President of Hardware Engineering in 2013 and joined Apple's executive team in 2021 as Senior Vice President of Hardware Engineering.
In his current role, Ternus oversees hardware engineering teams responsible for major Apple products, including the iPhone, iPad, Mac, Apple Watch, AirPods and Apple Vision Pro.
Education and Early Career
Ternus holds a bachelor's degree in Mechanical Engineering from the University of Pennsylvania. Before joining Apple, he worked as a mechanical engineer at Virtual Research Systems.
His engineering background is particularly significant because it gives Apple's next CEO extensive experience in product development and hardware engineering.
His Role in Apple's Products
During his more than 25 years at Apple, Ternus has been involved in the development of multiple generations of Apple products. Apple credits him with helping oversee the introduction of major product categories such as the iPad and AirPods, as well as work across the iPhone, Mac and Apple Watch lineups.
He has also played an important role in Apple's transition from Intel processors to Apple-designed silicon, a major change in the company's Mac strategy.
Ternus has increasingly become a familiar face at Apple product launches. He has presented products including the latest Macs, iPhones and AirPods, explaining the engineering and design decisions behind them.
Why Did Apple Choose Him?
Apple's board described Ternus as a leader with deep technical knowledge, strong leadership abilities and a strong understanding of Apple's products. Tim Cook also praised him as an engineer and innovator capable of leading Apple into its next phase.
His appointment suggests a degree of continuity rather than a dramatic change in Apple's direction. Ternus is an internal candidate who has worked closely with both Steve Jobs and Tim Cook during his Apple career.
What Happens to Tim Cook?
Tim Cook will step down as CEO on September 1, 2026, after leading Apple since 2011. He will become executive chairman and will continue to assist the company on certain matters, including engagement with policymakers. Ternus will also join Apple's board when he becomes CEO.
In short, John Ternus is not an outsider coming to Apple—he is a 25-year Apple veteran who has helped build many of the company's most important products. His promotion marks a significant leadership transition while keeping Apple firmly under experienced internal leadership.
