I'm surprised nobody has mentioned they make the Mac Pro in Cork.
I didn't know that. Very cool.

Apple's presence in Cork dates back to 1980. At the time, it was the company's first headquarters outside of the US. The location would eventually go on to be the main production facility for the computers like the iMac, but Apple then began outsourcing production to Wales and Singapore, eliminating 450 jobs in Cork.
The iPod and resurgent Mac sales helped return jobs to Ireland; Cork is now involved in supplying Europe, the Middle East, and Africa, and assembling the Mac Pro.
