    \enum QSysInfo::MacVersion

    This enum provides symbolic names for the various versions of the
    Macintosh operating system. On Mac, the
    QSysInfo::MacintoshVersion variable gives the version of the
    system on which the application is run.

    \value MV_9        Mac OS 9 (unsupported)
    \value MV_10_0     Mac OS X 10.0 (unsupported)
    \value MV_10_1     Mac OS X 10.1 (unsupported)
    \value MV_10_2     Mac OS X 10.2 (unsupported)
    \value MV_10_3     Mac OS X 10.3
    \value MV_10_4     Mac OS X 10.4
    \value MV_10_5     Mac OS X 10.5
    \value MV_Unknown  An unknown and currently unsupported platform

    \value MV_CHEETAH  Apple codename for MV_10_0
    \value MV_PUMA     Apple codename for MV_10_1
    \value MV_JAGUAR   Apple codename for MV_10_2
