Tim Cook’s parting message: Apple is in the hands of a product builder

On his last day as Apple CEO, Tim Cook offered a rousing endorsement of his successor: John Ternus , the company’s senior vice president of hardware engineering. In a memo to employees, Cook reminded staff that he’s “not leaving Apple,” just stepping away from the role of CEO, while declaring that “few people understand what it takes to build products that change the world the way John does.”

Ternus’ elevation to the top job suggests that Apple’s next era will see a renewed focus on hardware and product execution. Under Ternus, Apple shipped a number of notable products, most recently, the new ultra-thin iPhone Air, the lower-cost MacBook Neo, and AirPods with hearing health features. He also led the hardware engineering team across Apple’s full device lineup.

Hardware will play an important role in the AI era, not only in terms of chips, but also the devices people use to run enterprise AI. Apple this year, for instance, offered earlier releases of its new Mac models, the Mac mini and Mac Studio, compared with years past, driven by AI demand.

Cook’s memo, reported by Bloomberg and others, naturally says little about Apple’s future when it comes to AI, services, regulation, China, or the other challenges that lie ahead. Instead, Cook focuses on his gratitude for the opportunity to lead Apple and exalts the company’s culture as ultimately what matters most.

“We share a belief that what we build matters and that we have both the opportunity and the responsibility to leave the world better than we found it,” Cook wrote. He also referenced the famous Steve Jobs quote about leaving a “dent in the universe,” saying that Apple makes that possible because of “who we are and what we believe,” as well as “what we value and how we see the world.”

Cook will remain at Apple as executive chairman and will continue to manage political relationships, including those with President Trump and the Chinese government.

On X, Cook also wrote : “Sending lots of love to the Apple community on my last day as CEO. My title changes tomorrow, but the love I have for the Apple community never will. Thank you for being a constant source of inspiration. My gratitude is endless, and I’m excited for the next chapter!”

Today is my last day as CEO of Apple. This is a moment I always knew would come one day, and yet it is still hard to believe it has arrived and I am writing these words. I love this company and the team behind it, and I couldn’t let this day pass without sending a note to you to tell you how grateful I am for the outpouring of affection you’ve sent my way, for the way you’ve shown up each and every day, and most of all, for the privilege of a lifetime serving as your leader.
