John Ternus’ promotion to Apple CEO may have claimed its first casualty

Following this week’s surprise announcement that Tim Cook will step down from his role as Apple CEO in September, analysts are busy working out all the ramifications. Most obviously the Cook-shaped gap at the top of the company will be filled by a promoted John Ternus, but that in turn will lead to a succession of other changes, including both promotions and departures.

One senior member of staff who is weighing up his options, according to a report this week, is Mike Rockwell. In an article for Bloomberg, Mark Gurman warns that the new CEO faces an “exodus of top talent” and names Rockwell as one key employee who has been considering either leaving the company entirely or moving into an advisory role. (Such roles can be a fig leaf for departures which could spook the shareholders, as seems to have been the case with Jony Ive.) In both cases, the change would reportedly take place next year.

Rockwell became known to Apple fans through his supervisory work on Vision Pro. While it was something of a commercial flop, the success of this project (at least from a logistical and technical point of view), coupled with Siri’s ongoing failures, meant Rockwell was then tasked with improving Apple’s troubled voice assistant, an assignment that has conspicuously not been achieved at the time of writing.

According to Gurman, however, the magnitude of this task is not what has prompted Rockwell to think about leaving. Rather, the issue is about the new structure of Apple under Ternus, and Rockwell’s ability to advance within that. “He has had reservations about reporting to his new boss, software chief Craig Federighi,” Gurman explains, “and desires a larger role.” He doesn’t doubt his ability to fulfil the responsibilities currently assigned to him. He wants more of them.

Ternus doesn’t take up the CEO mantle until the fall, which leaves plenty of time for him to convince Rockwell of the merits of his vision for Apple. He may not even know yet how he wants to structure and run the company, although by all accounts, this is a transition that’s been in the works for some time. It’s also possible that Rockwell’s ambivalence about staying is a negotiating position intended to leverage his importance to the Siri project into a better role and job title. We’ll find out more later in the year, but Gurman feels it’s unlikely Rockwell will leave before the Siri revamp is complete. Cook and Ternus will hope that’s true.

But one thing’s for sure: Cook’s announcement is sure to spur some changes to key roles at Apple this year. John Ternus just has to ensure that acceptable churn doesn’t turn into a succession crisis.
