In a lengthy interview with Bloomberg Businessweek, Apple (AAPL) CEO Tim Cook confirmed that the company is making investments in an effort to move some Mac production back to the United States. “Next year we are going to bring some production to the U.S. on the Mac,” Cook told the magazine in an interview published on Thursday. “We’ve been working on this for a long time, and we were getting closer to it. It will happen in 2013. We’re really proud of it. We could have quickly maybe done just assembly, but it’s broader because we wanted to do something more substantial. So we’ll literally invest over $100 million. This doesn’t mean that Apple will do it ourselves, but we’ll be working with people, and we’ll be investing our money.” The news comes just days after it was revealed that at least some late-2012 iMac models are being assembled in the U.S.
