At 11:59 p.m. Beijing time on August 31, Tim Cook posted a message on Weibo, the Chinese social network, that ended with a promise: “Tomorrow my title will change, but my love for the Apple community will never change.” The post, addressed to Apple’s community in Chinese, came hours before Cook formally stepped down as chief executive, ending a 15-year run atop the world’s most valuable company.
The message was vintage Cook: understated, grateful and focused on the community rather than the corporate record. “On my last day as Apple’s CEO, I send my love to the Apple community,” he wrote. “Thank you for always being a source of inspiration. I am deeply grateful, and I look forward to the new chapter.” He signed off with the kind of warmth that has defined his public style, a contrast with the harder-edged personalities who dominate much of the technology industry.
Cook’s departure on September 1 had been planned and announced in advance, part of an orderly succession that the company has been preparing for years. John Ternus, the head of hardware engineering and the man most associated with Apple’s transition to its own chips, succeeds him. The handover, carried out on a specific date with a public farewell, was a deliberate counterpoint to the messy transitions that have marked other companies, where founders cling to power or executives leave under pressure.
The record Cook leaves is substantial. He took over from Steve Jobs in 2011, months before Jobs died, and presided over an era in which Apple’s market value grew from roughly $350 billion to more than $3 trillion. Under his leadership the company launched the Apple Watch, the AirPods and the transition from Intel processors to Apple silicon, while services grew into a business that generates more revenue than most technology companies. The iPhone, the product that defines Apple, kept selling in volumes that defied the skeptics who predicted its decline year after year.
The record also includes unresolved questions. Regulators in Europe and the United States have challenged Apple’s app store rules, its control over its platforms and its treatment of competitors, and those fights will land on Ternus’s desk. The company’s push into AI has been deliberate but slower than rivals, and investors have watched Google, Microsoft and OpenAI build large AI businesses while Apple’s contributions have been folded quietly into its devices. Cook’s last years were spent positioning Apple for the AI era, and the results of that positioning are not yet clear.
His farewell on Weibo underscored how much of Apple’s future depends on China. The country is Apple’s largest market outside the Americas, the home of its biggest manufacturing partner and the source of a growing share of its revenue. Cook has visited China more often than any other major American technology chief, and the Weibo post, written for a Chinese audience, was a deliberate gesture of continuity. The choice of platform said something about Apple’s priorities: of all the ways to say goodbye, Cook chose the one his Chinese customers would see first.
Ternus inherits a company with different challenges than Cook faced. The hardware era that made Apple famous is maturing, and the next act will be defined by services, AI and the regulatory battles that come with scale. Ternus has spent most of his career in hardware, and investors are watching whether he can manage the software and services side of the business with the same command. Cook’s farewell message, with its emphasis on the community, also signaled the tone Ternus will be expected to keep: Apple has always presented itself as a company that makes things for people, not just a business that sells products.
The transition also raises questions that Cook will watch from the sidelines. He is expected to remain close to the company, and Apple has said it will retain him as a senior figure during the handover, a common arrangement for outgoing chief executives. His successor’s first moves, the product roadmap for 2027 and the company’s approach to the AI competition will be read as signs of continuity or change. Cook spent his last years in office making the case that Apple’s careful approach to AI would pay off; Ternus will now have to prove it.
For the employees who received the message, it was the end of an era in the most personal sense. Many of them have worked their entire careers under Cook, and the Weibo post, in its way, was addressed to them as much as to customers. The new chapter begins with a new chief executive, a new generation of products and the same question that has followed Apple for two decades: whether the company that changed the world once can keep changing it.
