At this conference for investors, Tim Cook said: "We have also updated our MacBook lineup, will release launch Mountain Lion tomorrow and iOS 6 this fall." He also add that "we are excited to show you the new products we have in our pipeline."
The new version of Mac OS includes features inspired from the iOS Plateforme, the operating system of the iPhone, iPad, iPod Touch, such as the Airplay Mirroring, Game Center, an advanced integration of icloud.
Announcement of the availability of Mac OS Mountain Lion by Tim Cook is only two weeks after the Gold Master (GM) version,(which mean the system is ready for public release). When Apple have shipped the GM version of Mountain Lion to developpers, no major anomalies has been found. Instead, Apple had advised developers to focus on quality and graphics performance, image and other media importing, editing and display in general, and finally on the reliability and networking performance.
