The move comes amid growing trade tensions between the Trump administration and China.
"Like all of our products, the new Mac Pro is designed and engineered in California and includes components from several countries including the United States," Apple's statement said.
The company said manufacturing facilities in 30 states and spent $ 60 billion last year with more than 9,000 US suppliers.
Quanta Computers and Flex, which runs the plant in Austin, has responded to requests for comment.
The company's Austin production, where Mac Pro is put together and receive in "Assembled in the USA" stamp, is relatively small compared to that of the iPhone, which is manufactured in China and other countries. The Mac Pro, which starts at $ 6,000, is a niche product designed for professional users who need it for production rendering and video editing. The Mac Pro computer recently received its first design update in six years. It was designed by Jony Ive, Apple's chief designer who famously designed the iPhone, Apple's iconic candy-colored iMacs, and its spaceship-shaped headquarters. The company announced on Thursday he is leaving the company after 30 years.
The company has not yet announced the launch of the new Mac Pro computer.
