Tim Cook, in one of his last public appearances as Apple Chief Executive, visited a Texas factory with Commerce Secretary Howard Lutnick and showcased a new manufacturing school and an assembly line set to begin producing Mac Mini computers later this year. The tour underscored Apple’s alignment with the Trump administration’s effort to revive U.S. manufacturing, with the administration pointing to Apple’s domestic investment as a key example. The appearance also comes as Apple has avoided some of the heavy tariffs imposed by the administration.
