It appears that Apple is trying to add more internal components to manufacturing in the United States, specifically in Mesa, Arizona. It is about expanding the manufacture of components for own use and therefore it would not be about products for sale to users in general, rather it is about integrated circuit boards, batteries, monitors, servers and a series of components to be used directly in existing data centers or for new ones that they plan to open, but always internally and not to market with them.
It seems that the permission that the Cupertino firm itself has requested to manufacture more products has something to do with the harshness of Donald Trump's statements and the manufacture or assembly of the brand's products outside the country. The truth is that brands such as Ford, among others, have also been directly attacked by Trump, who wants to bring production to his country despite the increase in the cost of final products for both companies and users, despite saying that they will lower taxes or taxes for companies that take the step.
Right now the only product “made” in the United States is the 2013 Mac Pro, and this Mac that has internal components from Arizona, Texas, Illinois, Florida and Kentucky, It is not entirely American either, as some components are not made in the USA.. In any case, Apple's move is logical and good for everyone, since it would partly satisfy Trump and improve relations for the future even though we do not believe it is exactly what the new President of the country wants.
