Ternus Runs Apple Today, Cook Stays as Chairman
Ternus Runs Apple Today, Cook Stays as Chairman
The News
The handover is done
John Ternus is the chief executive of Apple as of Tuesday, September 1, formally ending Tim Cook's 15-year tenure at the top of the world's most valuable company.
Ternus, Apple's longtime hardware engineering chief, takes the job after building the machines that pay the company's bills. Cook spent Monday, his last day as CEO, sending an emotional memo to employees. "I will miss this work in ways I can only begin to imagine," he wrote, according to The Independent, adding that he was at peace with the decision.
Cook isn't going anywhere
This is the part that makes the handover unusual: the man Ternus replaces is still in the building.
Cook becomes executive chairman and keeps responsibility for Apple's political relationships — the tariff conversations, the Washington meetings, the government-facing work he has personally handled for years. MarketWatch framed the new CEO's first big challenge exactly that way: leading when his old boss is still around, in an expanded board role rather than out the door.
Cook plans to keep showing up at Apple Park and traveling in the new role.
What's Next
The inheritance
Ternus starts at a bad moment to be new. CNBC reported that his first day lands at a critical juncture, with memory prices soaring and AI challenges looming — a cost squeeze on hardware at the same time Apple is trying to catch up on software.
Business Insider listed the to-do list plainly: the AI race, Siri, talent losses, China, and Trump. Apple is, in CTV's phrasing, bigger and richer than ever and still playing catch-up in AI.
What nobody knows yet
How Ternus intends to fix Apple's AI position remains unclear — several outlets covering the transition say so explicitly, and Apple has not laid out a strategy under the new CEO. The same goes for how he will handle regulatory pressure and China.
That launch is now his first real audition in front of the public — and the first time anyone outside Cupertino gets to judge what the Ternus era actually is.

What Cook is handing over
By the numbers, the tenure is hard to argue with. CTV News reported that Cook took Apple from a roughly $350 billion company to a more than $4.5 trillion behemoth; abc27 put the current figure at $4.6 trillion. Either way, the iPhone did most of the lifting.
Business Insider's assessment was that Cook beat the odds of following Steve Jobs by pairing his own operational judgment with Jobs' values. The Verge marked the exit with a ledger of ten wins and ten misses across the 15 years.
What he has actually shipped
Ternus is not an unknown quantity inside Apple, even if he is outside it. Under his hardware leadership the company shipped the iPhone Air, the lower-cost MacBook Neo, and health-focused AirPods. Apple also released new Mac models earlier than usual in 2026, driven by enterprise demand tied to AI.
His elevation is the clearest signal Apple has given about where it thinks its advantage lies: the device.
He is also, by reputation, low-profile. The Independent called him a largely mysterious figure who will finally get to introduce himself properly with the iPhone 18 launch.
