Ternus is not a newcomer to Apple.
He has worked at the company since 2001 and currently serves as Senior Vice President of Hardware Engineering, where he has helped lead major product lines including the iPhone, iPad, Mac, Apple Watch, and AirPods.
Reuters described him as a hardware-focused insider, a choice that signals Apple may lean even more heavily on product engineering as it faces pressure in the AI era.
The transition marks the end of Tim Cook’s long run as chief executive, a period that began in August 2011.
Under Cook, Apple became one of the world’s most valuable companies, and his shift to executive chairman suggests continuity rather than a dramatic break in direction.
For many observers, this leadership change is more than a personnel update.
It has become a trending topic because Apple is entering a critical phase shaped by artificial intelligence, product competition, and investor expectations.
Ternus now inherits the challenge of proving that Apple can keep its hardware excellence while accelerating innovation in software and AI.
