Reports have emailed that Apple moved production to China, but that is not necessarily the case. Tim Cook mentioned during Apple's recent earnings call that the company wanted to continue making Mac Pros in the US and invested in additional capacity. Although Apple is mounting the reworked Mac in the US, however, the tariffs can still be painful. It is still likely that many of the parts Apple needs in China, and costs can increase rapidly.
The company is not alone either. Regulators also levied tariffs for electronics that affect other PC manufacturers, including those for sub-boards and graphics cards. If they had not done so, there was a good chance that many computers would become more expensive, including home-built PCs with Chinese parts. Apple has simply been one of the biggest targets, and is still facing significant cost increases if the United States proceeds with a new customs round on December 1
