Tim Cook steps down as Apple CEO after 15 years, handing leadership to John Ternus, a 35-year veteran of the company. The transition, while unexpected in timing, was widely anticipated given Cook's public hints about retirement plans. Ternus, previously senior VP of engineering, will now shape Apple's strategy as Cook transitions to executive chairman.

The move comes as Apple faces intensified scrutiny over FBI encryption demands, prompting iOS updates to block unauthorized access to user messages. Meanwhile, Star Wars filmmakers leveraged Apple's Vision Pro headset to reduce production costs, showcasing the device's industry impact.
