The era of Tim Cook at Apple has drawn to a close. On his final day as chief executive, the 65-year-old technology titan penned a heartfelt farewell memo to staff, reflecting on a remarkable 15-year tenure that transformed the company into one of the most valuable enterprises on the planet. With John Ternus officially stepping into the role on 1 September, the tech world watches as one legendary chapter closes and another begins.
A Leader’s Heartfelt Goodbye
Cook’s farewell message, obtained by 9to5Mac, reads with a rare vulnerability that few would expect from the steely executive who has guided Apple’s meteoric rise. “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,” he confessed to staff.
The memo drips with genuine emotion. Cook spoke of his deep affection for the company and its workforce, thanking employees for what he described as “the outpouring of affection you’ve sent my way.” He acknowledged the weight of stepping away from a position he had cherished, admitting he “will miss this work in ways I can only begin to imagine.” Even so, he insisted he remained “completely at peace with my decision.”
It is a striking moment of candour from a leader who has rarely been seen as emotionally expressive on the public stage.
The Legacy: A Trillion-Dollar Powerhouse
Under Cook’s stewardship, Apple achieved feats that would have seemed almost fantastical when he first took the reins from co-founder Steve Jobs in 2011. The company’s market capitalisation soared past the trillion-dollar threshold, cementing its status as the world’s most valuable corporation.
The product pipeline under his watch was nothing short of extraordinary. The Apple Watch redefined personal health technology. AirPods created an entirely new wireless audio category. And the Apple Vision Pro positioned Apple firmly at the frontier of spatial computing. Each launch represented a bold wager on where technology was heading — and each one paid off spectacularly.
Cook’s genius lay not in inventing new categories from scratch, but in refining and scaling them with a precision and commercial acumen that few in the industry could match. He turned brilliant engineering into beloved consumer products that billions of people carry in their pockets every single day.
John Ternus: The New Captain
John Ternus, Apple’s senior vice president of hardware engineering, officially assumes the CEO role today. The appointment, announced back in April, marks a significant moment for a company that has always placed hardware innovation at its very core.
Ternus brings nearly a quarter-century of experience to the position, having first joined Apple as part of the product design team some 25 years ago. When news of his elevation broke, he expressed being “profoundly grateful,” reflecting on his journey from junior designer to chief executive. He noted that he had been fortunate to work under both Steve Jobs and Tim Cook, describing Cook as a mentor who shaped his approach to leadership.
“I am humbled to step into this role, and I promise to lead with the values and vision that have come to define this special place for half a century,” Ternus pledged, signalling continuity with the principles that have guided Apple since its earliest days.
Cook himself made a point of championing Ternus’s hardware credentials in his farewell note, claiming that “few people understand what it takes to build products that change the world the way John does.” The endorsement was clear: Apple wanted a leader who understood the craft of engineering at the deepest level.
The Road Ahead: iPhone 18 and Foldable Tech
Ternus faces an immediate and formidable challenge. Just days into his tenure, he must preside over Apple’s most anticipated product showcase of the entire year. Industry watchers are bracing for the unveiling of the iPhone 18 Pro, a refreshed lineup of Apple Watches, and — perhaps the most tantalising announcement of all — the company’s very first foldable smartphone.
That last product alone represents a generational leap for Apple. The foldable smartphone market has been dominated by competitors, and Apple’s entry promises to reshape the landscape entirely. Ternus’s hardware engineering background makes him the natural choice to shepherd such a flagship device into the world.
The pressure is immense, but few doubt he is up to the task.
Why it Matters
Tim Cook’s departure is more than a leadership transition — it is the end of an era that redefined modern technology. His 15-year tenure proved that steady, disciplined stewardship could elevate a company to unprecedented financial and cultural heights, all while delivering products that reshaped how humanity communicates, creates, and cares for its health. As John Ternus steps into the spotlight, the tech world will be watching closely to see whether he can sustain Apple’s momentum at a time when competition is fiercer than ever and consumer expectations have never been higher. The next chapter of the world’s most influential technology company has officially begun, and it promises to be every bit as compelling as the last.
