像这样的东西:

    [DllImport("/System/Library/Frameworks/CoreServices.framework/CoreServices")]
    internal static extern short Gestalt(int selector, ref int response);
    static string m_OSInfoString = null;
    static void InitOSInfoString()
    {
        //const int gestaltSystemVersion = 0x73797376;
        const int gestaltSystemVersionMajor = 0x73797331;
        const int gestaltSystemVersionMinor = 0x73797332;
        const int gestaltSystemVersionBugFix = 0x73797333;

        int major = 0;
        int minor = 0;
        int bugFix = 0;

        Gestalt(gestaltSystemVersionMajor, ref major);
        Gestalt(gestaltSystemVersionMinor, ref minor);
        Gestalt(gestaltSystemVersionBugFix, ref bugFix);

        if (major == 10 && minor == 5)
            RunningOnLeopard = true;
        else
        {
            RunningOnLeopard = false;
            if (major == 10 && minor == 7)
                RunningOnLion = true;
        }

        m_OSInfoString = string.Format("Mac OS X/{0}.{1}.{2}", major, minor, bugFix);
    }
