John Ternus has officially taken over the helm of Apple succeeding Tim Cook after his 15 years tenure; This marks a meteoric rise for Ternus who has spent 25 years at Apple, rising from a product design engineer to the executive responsible for the company’s entire hardware engineering organisation.
While Cook was primarily known for operations, supply-chain management and expanding Apple’s services business, Ternus comes from the engineering and product-development side of the company.
From Mechanical Engineering to Apple CEO
Ternus studied mechanical engineering at the University of Pennsylvania, graduating in 1997. Before joining Apple, he worked as an engineer designing virtual-reality headsets at Virtual Research Systems.
He joined Apple in 2001 as a member of the company’s Product Design team. His first known project was the Apple Cinema Display, beginning a career that would eventually put him in charge of hardware engineering across virtually the entire Apple product portfolio.
In 2013, Ternus became vice-president of Hardware Engineering. His responsibilities included major product lines such as the Mac, iPad and AirPods. In 2020, his portfolio expanded to include iPhone hardware engineering.
Ternus was promoted to senior vice-president of Hardware Engineering in 2021, succeeding Dan Riccio. In that position, he became responsible for the engineering teams behind the iPhone, iPad, Mac, Apple Watch, AirPods and Apple Vision Pro.
As Apple’s hardware chief, Ternus has been involved in the development and evolution of several of the company’s most important products spanning the iPhone, iPad, Mac, Apple Watch, AirPods and Vision Pro, giving him unusually broad knowledge of the company’s product architecture and engineering culture.
Different Leadership Challenge
Cook transformed Apple into a services powerhouse while maintaining the strength of its hardware ecosystem. Under his leadership, products such as the Apple Watch, AirPods and Vision Pro joined the iPhone, Mac and iPad, while services became a major source of recurring revenue. Apple’s market value also expanded dramatically during his tenure.
Ternus now faces a different strategic environment as he inherits an Apple that is considerably larger and more diversified than the company Cook took over in 2011.
Apple has been under pressure to accelerate its AI capabilities as competitors such as Google and Microsoft invest heavily in generative AI and AI infrastructure. Ternus will therefore have to determine how aggressively Apple should invest while preserving its traditional emphasis on tightly integrated hardware, software and services.
The company’s supply chain and relationship with China will also remain critical issues as Apple depends heavily on Asian manufacturing networks while China remains both an important production base and consumer market.
First Major Test
Ternus will barely have time to settle into the CEO role before appearing at one of Apple’s most important annual events. Apple is scheduled to hold its major iPhone launch event on September 9, 2026, just eight days after Ternus becomes CEO.
The company is expected to unveil its next-generation iPhone lineup, with reports also pointing to the possibility of Apple entering the foldable-phone market with the event providing an early indication of how he communicates Apple’s product strategy and how investors and consumers respond to the new leadership.
The possibility of a foldable iPhone is particularly significant because it would represent one of Apple’s biggest hardware-category expansions in years and place the company directly against Samsung and other established players in the foldable market.
For Ternus, the transition from Apple’s hardware chief to CEO also represents a shift from designing and engineering products to deciding the company’s overall strategic direction.
