Apple COO Jeff Williams is retiring after 27 years. His exit marks another recent major leadership shift at the company.

Jeff Williams has been Apple's Chief Operating Officer since 2010, but he's begun his retirement process and will be passing the reins to Sabih Khan.

Tech giant Apple has appointed Sabih Khan as its new Chief Operating Officer (COO), marking a significant leadership transition as long-serving executive Jeff Williams prepares to step down later this month.
