WWDC 2026 marked more than the arrival of iOS 27, Siri AI and Apple's latest software updates. It also marked the final WWDC led by Apple CEO Tim Cook, bringing an end to his remarkable 15-year run at the company's helm.
When Cook took over from Steve Jobs in 2011, many saw him as the operations expert tasked with keeping Apple's machine oiled up and running. Few expected him to oversee one of the most successful eras in tech history, transforming Apple from a company worth roughly $350 billion into a business valued at trillions.
As Cook prepares to hand over the reins to John Ternus, who previously served as Senior Vice President of Hardware Engineering, these are some of the key moments that defined his legacy.
The Apple Watch Proved Apple Could Innovate Without Steve Jobs
Perhaps the biggest question hanging over Apple after Jobs' passing was whether the company could still create a category-defining product. The answer arrived in 2014 with the Apple Watch.
What started as an iPhone companion device evolved into one of the world's most popular wearables and a serious health and fitness device. More importantly, the Apple Watch showed that Apple could successfully enter entirely new categories without relying on the iPhone for growth.
Looking back, this was arguably the moment when Apple truly became Tim Cook's Apple.
AirPods Redefined Music Listening
When the Cupertino giant removed the headphone jack from the iPhone 7 back in 2016, the backlash was understandable and immediate. Then, the AirPods arrived.
What initially looked like a risky move quickly became one of Apple's greatest successes. AirPods didn't just popularise truly wireless earbuds, they effectively created a market that almost every smartphone brand now competes in.
Today, it's difficult to imagine the consumer tech industry without wireless earbuds, and that shift alone began under Cook's leadership.
iPhone X Reinvented the iPhone
The iPhone X was one of the boldest products Apple released during the Cook era. Launched in 2017 to celebrate the iPhone's 10th anniversary, the iPhone X replaced Touch ID with Face ID, thereby eliminating the physical Home button altogether.
This gave Apple iPhones the modern, all-screen smartphone design that the brand still follows today. More than anything, the iPhone X proved that Apple was still willing to take major risks with its most important product.
Apple Became the World's First Trillion-Dollar Company
In 2018, Apple achieved something no publicly traded company had done before, and that is crossing a market valuation of $1 trillion (nope, I can't convert that to Rupees, sorry).
The milestone wasn't tied to a single product launch. Instead, it reflected Cook's broader strategy of expanding Apple's ecosystem through hardware, software and services.
For a CEO often criticised for being more operational than visionary, the achievement served as a more powerful reminder that execution can be just as important as invention.
Apple TV+ Turned Apple into an Entertainment Giant
Under Cook, Apple gradually evolved from a hardware company into a services powerhouse, and that says a lot. One of the most ambitious steps that came into this was Apple TV+, which was first unveiled as part of Apple's growing services strategy back in 2019.
Alongside Apple Music, iCloud, Apple Pay and other subscription businesses, Apple TV+ helped create an ecosystem that extends far beyond devices. Today, Apple's service business alone generates revenue that many Fortune 500 companies would envy.
For instance, Apple's Q2 2026 Earnings Call reported an all-time high revenue of roughly $31 billion.
Apple Silicon May Be Cook's Greatest Achievement
If there is one moment that tech enthusiasts will remember most from the Cook era, it may be Apple's transition away from Intel processors. The introduction of Apple Silicon in 2020 completely transformed the Mac.
The first M1-powered Macs delivered unbelievable gains in performance and battery life while proving that Apple could control every major piece of technology inside its products. The move has since become one of the most successful platform transitions in computing history.
Even six years later, competitors are still chasing the efficiency-to-performance ratio Apple established with its custom chipsets.
MacBook Neo Shows Cook Never Stopped Expanding the Mac
One of the final major products introduced during Cook's tenure was the MacBook Neo. Designed to bring the Mac experience to more people than ever before, the affordable laptop ($599 in the U.S. and Rs 69,900 in India) became Apple's most accessible Mac as of today.
To give you a better idea, as per a report from industry analyst IDC (via TechCrunch), Apple shipped a staggering 1.1 million units of MacBook Neo in Q1 2026. That's way over the 900,000 units of the MacBook Air M5 and 550,000 units of the MacBook Pro M5 that Apple shipped during the quarter.
Most importantly, it came in as solid proof that Cook's long-standing focus has always been on growing the ecosystem rather than simply targeting the premium end of the market. It's fitting that one of Cook's final hardware stories was about making the Mac more attainable.
The Legacy of Tim Cook's Era at Apple
Tim Cook may never be remembered in exactly the same way as Steve Jobs. But he doesn't need to be. Jobs built modern Apple, while Cook scaled it into one of the most powerful companies the world has ever seen.
From the Apple Watch and AirPods to Apple Silicon and a trillion-dollar valuation, Cook's greatest achievement wasn't a single product. It was proving that Apple could continue to evolve long after its iconic founder was gone.
With its first foldable incoming with the iPhone Ultra and the newly announced iOS 27 update, which finally brings Apple to the forefront in the AI race, the Cupertino giant shows no signs of slowing down. Judging by the company he leaves behind after WWDC 2026, that's a legacy few CEOs could never hope to match.
Thank you for everything, Tim.
