CUPERTINO, California, January 16, 2026 — Apple has quietly expanded the responsibilities of senior vice president of hardware engineering John Ternus, giving him oversight of additional product categories and increased influence over company-wide engineering decisions, according to people familiar with the matter.
The move positions Ternus, 50, as a stronger internal contender in discussions about long-term leadership succession. CEO Tim Cook, who turned 65 last November, has not publicly indicated any retirement plans, but the shift in responsibilities has fueled renewed speculation about who might eventually succeed him.
Ternus, who has led hardware engineering since 2021, now oversees a broader portfolio that includes Mac, iPad, iPhone, Vision Pro, and emerging product lines. Previously focused primarily on Mac and iPad, his expanded remit brings him closer to the scope once held by former chief design officer Jony Ive and operations chief Jeff Williams.
The change aligns with Apple’s tradition of preparing multiple internal candidates for senior roles. Other executives frequently mentioned in succession discussions include services chief Eddy Cue, chief operating officer Sabih Khan, and retail chief Deirdre O’Brien.
Ternus joined Apple in 2001 as a mechanical engineer and rose through the Mac hardware ranks. He played key roles in the transition to Apple silicon and the development of the Mac Studio and Mac Pro. Colleagues describe him as technically deep, collaborative, and respected across engineering teams.
Apple has not commented on internal organizational changes or succession planning. The company maintains that Cook intends to remain CEO for the foreseeable future, with no formal transition timeline.
The expanded role for Ternus comes as Apple navigates several strategic challenges, including slower-than-expected adoption of Apple Intelligence features, regulatory pressure in Europe and the U.S., and intensifying competition in AI and mixed reality.
The shift also coincides with recent executive departures and restructurings in the AI division, including the retirement of AI chief John Giannandrea in 2026 and the appointment of Amar Subramanya to lead AI and machine learning.
While succession remains speculative, Ternus’s increased scope positions him as a leading internal candidate with deep hardware expertise and broad organizational exposure.
