How John Ternus’s era will shape Apple
Coming from a botched AI launch that culminated in a $250 million class-action settlement in May, Apple needs to show that its user interface is as much class-leading as its hardware
Under Tim Cook's leadership, Apple secured a market capitalization of $4.6 trillion, established a highly efficient supply chain for selling over three billion iPhones, and successfully managed Steve Jobs' legacy. However, the foundation for these achievements lay in the hardware engineering provided by John Ternus. Ternus, who joined Apple's cinema display team in 2001, contributed to the development of the iconic Cinema Display monitor and the iPhone, which revolutionized mobile telephony with its innovative design.
In 2010, he became vice president of hardware engineering, overseeing the development of Apple's consumer hardware, including the iPad and iPad Air. In 2021, Ternus was appointed global head of hardware engineering, reporting directly to Cook and managing product lines across Apple's product portfolio. Ternus' contributions include introducing new product lines like AirPods and iPadOS, as well as pushing for the creation of iPadOS as a distinct operating system.
The iPhone Air, launched in 2025, exemplifies Ternus' approach to hardware engineering, combining a unique design with cutting-edge technology, such as the A19 Pro chip, Apple's N1 wireless chip, and the C1X modem. This highlights the collaborative effort between Ternus' hardware engineering team and Johny Srouji's chip teams, working together to design devices from the earliest stages of development.
Srouji, who joined Apple in 2008 and played a pivotal role in developing Apple's first custom chip, the A4, now oversees Apple's entire in-house silicon operation. The A-series chips power the iPhone and iPad, the M-series chips run Apple's Macs, iPad Pro, and Vision Pro, while the C-series handles cellular modems. The integration of the modem effort, which took six years after Apple acquired Intel's smartphone modem business, showcases the importance of Ternus and Srouji's roles in Apple's hardware development.
With Ternus' promotion and Srouji's expanded role as chief hardware officer, Apple's product engineering functions are more tightly integrated, signaling a potential for delivering a strong lineup of premium products. Apple is rumored to unveil a foldable phone in September, and under Ternus' leadership, the company may also venture into the smart-glasses segment and enhance the capabilities of its Vision Pro product.
Beyond hardware, Ternus must coordinate the integration of software developments with the hardware built by Srouji's team, particularly as Apple navigates its recent AI challenges. This marks a shift from Cook's focus on operational excellence to Ternus' emphasis on delivering a signature AI product.
