Apple's new CEO, John Ternus, takes over from Tim Cook after 15 years

John Ternus becomes Apple’s CEO, ending Tim Cook’s 15-year run that helped grow the company to a roughly $4.6 trillion valuation.
He takes over at a pivotal moment as Apple tries to catch up in AI after early stumbles, rolling out recent Siri and privacy-focused AI updates.
A hardware veteran (Apple Watch, AirPods, Vision Pro), Ternus will lead next week’s iPhone launch and handle supply-chain and leadership relationships while Cook moves to executive chairman.
