In recent years, Apple has seen a series of executive departures. CFO Luca Maestri retired in January 2025, followed by COO Jeff Williams in July of the same year. In December of the same year, John Giannandrea , who served as Apple's Senior Vice President of Machine Learning and AI Strategy, and Alan Dye , head of UI design, also left the company.
Bloomberg points out that the departures of Apple executives are partly due to Apple's struggles in the AI field, as well as the fact that many of those at the top of the organizational structure have amassed considerable wealth and are now prioritizing time with their families. In this context, there are whispers that Cook may step down as CEO as early as 2026. The leading candidate to succeed him is Turnus, who oversees hardware development, which accounts for about 80% of Apple's revenue.
At 50, relatively young compared to other senior executives, Turnus has spent roughly half his life at Apple. He started his career developing computer monitors, then oversaw the product design of the first iPad, and eventually became the head of Mac development. Since becoming head of hardware engineering in 2021, he has overseen the expansion of Apple's product lineup, focusing on improvements in functionality such as quality, battery life, performance, and connectivity.
As evidence of the considerable trust already placed in Turnus, he was the one to speak at the event in March 2026 where the MacBook Neo, priced at 99,800 yen (including tax), was announced , and the following day he appeared on the talk show Good Morning America. These media appearances were previously reserved for Cook. Simultaneously, Turnus's responsibilities have steadily expanded; in 2025 he took charge of the robotics development team and also took on a significant role in Apple's product marketing.
Current and former employees who have worked closely with Turnus testify that he made significant contributions to Apple's hardware product line, reversing the trend of quality sacrificing quality in pursuit of thinness and sophisticated design. Tony Blevins, who served as Apple's head of procurement until 2022, said, 'He is a very meticulous engineer and a shrewd executive,' suggesting that it would be natural to select Turnus as the next CEO.
Bloomberg reports that Turnus is known for his calm demeanor and strong political skills, and is very popular among Apple's management, including Cook's close associates. Colleagues describe Turnus as a 'good communicator who motivates employees,' and that his style is similar to Cook's, with a tendency to avoid risks and disrupting Apple's current state. One veteran executive said, 'If you think Cook is doing a good job, then you'll think Turnus is doing a good job too.'
On the other hand, it has been pointed out that Apple has been lagging behind in the field of AI in recent years, and some believe that it will be difficult for Turnus, who is not the type to try to break the status quo, to bring about the transformation necessary for Apple to continue to thrive. However, Turnus has acknowledged that Apple is lagging behind in the field of AI and recognizes that bolder products and approaches to AI are needed. In fact, Turnus is overseeing the development of an unreleased range of AI-powered home devices, wearable devices that use computer vision to perceive their surroundings (such as glasses, AirPods, and pendants), as well as a foldable iPad and a foldable iPhone.

While it remains unclear what kind of AI-powered devices Apple will release, hardware projects do align with Turnus's strengths. 'Tarnus is the only person in management with a proven track record of delivering integrated hardware and software products, and he's also the age to take on the role,' a source familiar with the situation told Bloomberg. This source added that Turnus is a suitable choice if Apple continues its strategy as a leading consumer electronics manufacturer, but the justification for choosing him weakens if the company shifts its focus to software and services.
Bloomberg stated, 'While Jobs was a product innovator and Cook a supply chain genius, Turnus ensures that products are actually developed. He has built his career in product development and has a deep understanding of the effort that goes into it. He is very tech-savvy and often digs into the details in meetings, and he often says that Apple's corporate culture is rooted in hiring engineers who push the boundaries. This could make Turnus a completely different CEO than the previous two.'
Apple's hardware and software teams had long been in a state of internal conflict, but under Turnus's leadership, they built a symbiotic relationship, working particularly closely with Craig Federighi, Senior Vice President of Software Engineering. Turnus's ability to mediate was crucial in transitioning Macs from Intel chips to Apple's own chips and releasing new types of products such as iPads with OLED displays. He also strongly advocated for the development of iPadOS to maximize the iPad's capabilities and persuaded Federighi, which greatly contributed to the later productivity improvements of the iPad.
On the other hand, Turnus has also experienced failures, such as promoting the Touch Bar , which replaced the physical keys on the top row of the MacBook Pro keyboard with a touchscreen, and introducing the poorly received butterfly keyboard. The butterfly keyboard was intended to create thinner devices, but it was difficult to use and had problems with noise and performance, so Apple was sued in a class-action lawsuit and forced to pay a settlement of $50 million (approximately 8 billion yen).

Bloomberg points out that if Turnus becomes Apple's next CEO, he will face the same challenge as Cook: 'Can he find Apple's next mega-hit product?' Turnus has often taken a conservative stance when Apple has ventured into major product categories such as cars and headsets. As a result, these product lines, including cars and headsets, were unsuccessful, and Turnus himself acknowledges that he bears some responsibility for Apple's slow start, as he was initially reluctant to invest in home devices, which later became increasingly important.
Furthermore, if the CEO were to change while President Donald Trump is still in office, the challenge would arise of how Turnus, succeeding Cook who worked hard to build a relationship with Trump, would maintain that relationship. However, sources close to Apple have suggested that Cook will likely continue to play the role of Apple's 'chief diplomat' even after stepping down as CEO.
