For the last 22 years, Serlet has been working with Apple CEO Steve Jobs, first at NeXT, the company Jobs founded after he left Apple in 1985, and later at Apple itself when Jobs returned in 1997. In that capacity, Serlet had a major role in the creation and development of Mac OS X.
Serlet will be succeeded by Apple’s current vice president of Mac software engineering, Craig Federighi. Like Serlet, Federigihi is a NeXT veteran who joined Apple in 1997. However, Federighi left the company in 1999 and spent ten years at software company Ariba, where he served as vice president of Internet services and chief technology officer among other posts.
Federighi later returned to Apple in 2009 to head up the company’s Mac OS X engineering team, a job he’s held ever since. He has both a master’s degree in Computer Science and a bachelor’s degree in electrical engineering and computer science from the University of California, Berkeley.
“Craig has done a great job managing the Mac OS team for the past two years,” said Serlet in Apple’s press release. “Lion is a great release and the transition should be seamless.”
