Apple announced that Jeff Williams, the company's chief operating officer who has served for 27 years, will retire later this year. It is reported that since being promoted to chief operating officer in 2015, Williams has been responsible for Apple's overall global operations as well as customer service and support. He also led the engineering development of Apple Watch and related projects in the health field, and took over Apple's design team in 2023.
