A historic leadership transition at Apple Inc. signals a decisive shift towards engineering-led innovation as John Ternus prepares to succeed Tim Cook as CEO. Cook, who has led the company since 2011, will transition to the role of executive chairman while remaining CEO through the summer, with the handover confirmed for 1 September 2026.
Ternus, 51, currently serves as Apple's senior vice president of hardware engineering.Bloomberg's Mark Gurman, who profiled Ternus in March 2026, consistently identified him as the most likely successor following former chief operating officer Jeff Williams's reduced operational role in 2025.

At 51, Ternus represents a blend of technical depth and institutional continuity. A mechanical engineer by training, he joined Apple in 2001 and steadily rose through the ranks to become senior vice president of hardware engineering.
Over more than two decades, Ternus has overseen the development of nearly every major Apple product. His work spans theiPhone, iPad, Mac, and AirPods, placing him at the centre of the company's most commercially significant innovations. He also played a pivotal role in Apple's transition to in-house silicon, a move widely regarded as one of the company's most important strategic decisions in recent years.
Cook praised Ternusin Apple's official announcement, saying he has 'the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and honour. He is a visionary whose contributions to Apple over 25 years are already too numerous to count, and he is without question the right person to lead Apple into the future.' Ternus said in response: 'I am profoundly grateful for this opportunity to carry Apple's mission forward. Having spent almost my entire career at Apple, I have been lucky to have worked under Steve Jobs and to have had Tim Cook as my mentor.'

Ternus's journey began at the University of Pennsylvania, where he earned a degree in mechanical engineering in 1997. Beyond academics, he was also a competitive swimmer, reflecting an early combination of discipline and performance.
Before joining Apple, Ternus worked at Virtual Research Systems, a firm involved in early virtual reality technologies. This experience exposed him to emerging interfaces and display systems — knowledge that would later prove relevant as Apple expanded into immersive technologies.
His early years at Apple coincided with a transformative era under Steve Jobs. Starting on the product design team, Ternus contributed toMac hardwarebefore advancing to leadership roles.
