A 25-year Apple veteran, John Ternus joined the company as a mechanical engineer and went on to oversee hardware teams behind the iPhone, iPad, Mac, Apple Watch, and AirPods.
John Ternus took over as Apple’s Chief Executive Officer on September 1, 2026, ending Tim Cook’s 15-year tenure and beginning a new chapter for the world’s most valuable technology company.
Ternus is not an outsider brought in to reshape Apple. He has spent his entire Apple career inside the company’s hardware organisation, rising from the Product Design team to Senior Vice President of Hardware Engineering before taking the top job.
Cook has moved to the role of Executive Chairman, where he will continue supporting Apple on selected matters, including engagement with policymakers. Apple said the transition followed a long-term succession process and was unanimously approved by its board.
From Mechanical Engineer to Apple’s Hardware Chief
Ternus joined Apple’s Product Design team in 2001, after working as a mechanical engineer at Virtual Research Systems. He holds a bachelor’s degree in mechanical engineering from the University of Pennsylvania.
He became Vice President of Hardware Engineering in 2013 and joined Apple’s executive team as Senior Vice President in 2021.
His career has been closely tied to the company’s most important hardware products. He has overseen engineering work across the iPhone, iPad, Mac, Apple Watch, AirPods, and Apple Vision Pro, including the development of new product categories.
That experience makes his promotion notable for another reason. Apple has chosen an engineer deeply involved in product development to lead the entire company.
The Products Behind His Rise
Ternus was already a senior hardware leader when Apple formally elevated him to its executive team in 2021.
At the time, Apple credited him with overseeing the first-generation AirPods, every generation of iPad up to that point, the iPhone 12 and iPhone 12 Pro hardware teams, and important work on the transition of the Mac to Apple silicon.
His responsibilities later expanded across Apple’s hardware portfolio.
Apple’s current leadership profile also points to his work on product reliability, materials and repairability. He helped drive the use of recycled aluminium, 3D-printed titanium in Apple Watch Ultra, and other hardware changes aimed at reducing the environmental impact of Apple’s products.
In other words, Ternus’ background is not limited to engineering individual components. His career has involved making decisions about how Apple’s products are designed, manufactured, and developed at scale.
Why Tim Cook Chose Ternus
Apple announced the succession in April 2026, several months before the formal handover.
Cook described Ternus as a leader who had spent 25 years building Apple products and said he had the experience and character required to lead the company. Apple also highlighted his broad experience across the company’s hardware categories.
The choice continues a pattern that has defined Apple’s leadership for years: promoting executives who understand the company’s products and internal culture rather than bringing in a CEO from outside.
Ternus’ appointment also means the transition comes with substantial institutional knowledge already inside the CEO’s office.
The Scale of the Company He Inherits
Ternus takes over a company that has changed dramatically during Cook’s tenure.
When Cook became CEO in 2011, Apple’s market capitalisation was approximately $350 billion. By the time the succession was announced, Apple said its market capitalisation had reached approximately $4 trillion, while annual revenue had risen from $108 billion in fiscal 2011 to more than $416 billion in fiscal 2025.
Apple’s services business has also become a major source of revenue, exceeding $100 billion annually, while its active installed base has grown to more than 2.5 billion devices.
Ternus therefore inherits an Apple that is much larger and more diversified than the company Cook took over.
The Challenge of Moving Beyond Hardware
Ternus’ strongest credentials are in hardware, but Apple’s next phase extends well beyond product engineering.
The company now operates a huge services business spanning the App Store, iCloud, Apple Music, Apple Pay, Apple TV and other offerings. It also has a growing interest in artificial intelligence and increasingly complex competition across smartphones, personal computing and emerging technology categories.
His engineering background could shape how Apple approaches those opportunities, but his role as CEO will require decisions across the entire business, from services and software to supply chains, regulation and global markets.
That makes the transition more than a change in title from hardware chief to CEO.
A Different Kind of Succession
Apple’s leadership change was years in the making, but the company has avoided a prolonged public succession contest.
Cook remained CEO through August, working with Ternus before formally handing over the position on September 1. He now remains connected to Apple as Executive Chairman.
Ternus’ appointment gives Apple a leader who knows the company’s products from the inside and has spent decades working within its design and engineering culture.
The question now is what he chooses to build beyond the hardware roadmap he already knows so well.
For 25 years, John Ternus helped decide how Apple’s products should be engineered.
As CEO, he now has to decide where Apple goes next.
