Apple announced March 23 that Bertrand Serlet, its senior vice president of Mac software engineering, is leaving the company. Taking his place will be Craig Federighi, currently Apple's vice president of Mac software engineering and presumably the next in command under Serlet.
Apple is losing its top Mac OS X executive just months before the computer giant is expected to release the next version of the PC operating system, dubbed Mac OS X Lion.
Apple didn't say exactly when Serlet would be leaving, why he's going or what new position he has lined up. In a statement, Serlet indicated that he's looking to shift his focus.
