John Ternus is Apple's new CEO, and I'm thankful for everything Tim Cook built

As of today, John Ternus is the CEO of Apple. Tim Cook has moved into the role of executive chairman, and a twenty five year Apple veteran who spent the last five years running Hardware Engineering now has the corner office. I've been looking forward to this moment for a while, and Ternus's first few hours on the job already tell you something about the kind of leader he's going to be.

But before I get to any of that, I want to sit with what Cook is handing off.

Thank you, Tim.

it's easy to get swept up in what comes next and forget how improbable the last stretch has been.

When Cook took over in 2011, plenty of people assumed Apple's best days had left with Steve Jobs. Instead, Cook spent the next decade and a half building one of the most successful companies in history.

Apple Watch created a new life saving category. AirPods became a cultural staple. Apple Silicon turned the Mac into something genuinely new and extremely powerful.

Services grew into a business the size of a Fortune 500 company on its own. And Apple became the first company on earth to cross a $3T dollar valuation.

That's not a good run. That's an unparalleled one and i believe Tim Cook to be the most successful CEO of a mega corporation in modern history.

What I'll remember most, though, is the tone he set. Cook ran the most valuable company in the world without ever seeming like he needed to prove anything, and he leaves it stronger, calmer, and more respected than he found it. As an Apple fan, I'm just grateful I got to watch it happen, and im grateful Apple had a Tim Cook.

A calm, confident first day

Ternus didn't come out swinging with a manifesto. He sent a short note to the team, joined X for the first time, and let Apple's own updates do most of the talking. That restraint feels intentional, and honestly very on brand for him.

His first message to employees was warm and brief.

He thanked the company for the welcome, spent most of the note praising Cook, and pointed everyone toward next week. The line that stuck with me, where he describes the CEO Apple is losing at the top:

We're so lucky to have had a CEO who led with his values and with such decency and humanity.

He also called Apple "the greatest company in the world," teased "a huge launch next week," and hinted at products "we haven't even imagined yet." It's the kind of note that sets a tone without overpromising.

Then there's the X account. Ternus quietly showed up on the platform as @johnternus, with a bio that reads, in full, "CEO."

His first post was a single lowercase "hello" with no punctuation. Marketing chief Greg Joswiak quoted it with "Hello, indeed. More to say September 9." If you were hoping the new guy would keep Apple's understated sense of humor intact, that's a pretty good sign.

Apple also refreshed its leadership page and Ternus's official bio, and reportedly gathered employees at Apple Park to introduce him and celebrate Cook one more time.

What his priorities tell us

The most revealing thing Ternus did today wasn't a speech. It was a paragraph.

Apple rewrote his bio, and the single new section it added takes up almost half the page. It's all about hardware reliability and durability, innovation in materials, a smaller carbon footprint, and products that last longer. It name checks a new recycled aluminum compound now used across several product lines, 3D printed titanium in the Apple Watch Ultra, and repairability improvements that stretch the lifespan of Apple gear.

Read that as a mission statement.

Ternus is a product person, not an operations person, and where Cook made his name mastering Apple's supply chain, Ternus made his building the things that supply chain produces. The bio tells you he plans to keep pushing on Cook's environmental goals while making the hardware itself the headline again.

There's movement behind the scenes too. Longtime finance leader Luca Maestri is stepping back from his corporate services role, with those duties shifting to CFO Kevan Parekh. M&A chief Adrian Perica is off the new leadership page, which some read as a hint that Ternus may chase bigger acquisitions than Cook ever did. And Laura Legros, a former Apple VP he pulled out of retirement, is said to be taking a chief of staff style role, something Cook never had. Reports also suggest Ternus won't keep outgoing executives around in smaller roles the way Cook liked to. Different CEO, different playbook.

What I'm watching next

The real test starts next Wednesday.

September 9 brings Apple's fall event, new iPhones, new Apple Watches, and the first big keynote of the Ternus era. His X account, so far one lonely "hello," is about to get very busy.

A product obsessed engineer running Apple, with Cook still in the building as executive chairman, is close to a best case scenario for the kind of Apple I want to keep using. But today, I'm mostly just saying thanks.

What are you hoping to see from Ternus? And what's your favorite moment from the Cook era?
