Microsoft taps new Mac chief

Microsoft appointed Roz Ho Wednesday as general manager of its Macintosh Business Unit, which produces software for Apple Computer's Macintosh operating system. The appointment ends uncertainty about who would run the Microsoft Mac unit following the move of former head Kevin Browne to the Xbox business unit.

Ho, who had been manager of the Macintosh Business Unit's Silicon Valley operation, will take charge of the unit's staff of 150 and software products, which include Office v.X for Mac, MSN Messenger 3.0 for Mac and also the forthcoming MSN for Mac OS X, due next year.
