Job's mob is hoping that it has put its troubled results behind it and is talking up the success of its Mountain Lion operating system.

Apparently since it was launched a four days ago it has had three million downloads which makes it the “most successful OS” in Cupertino’s history. The claim from Philip Schiller,who is the senior vice president of Worldwide Marketing, although we would have thought that other operating systems might have sold a few more copies.  The only difference is that this was downloaded in four days which is not bad.

Mountain Lion has a new Messages app, dubbed Notification Center which is derived from the iPhone and iPad whereby text messages sent to those devices will also show up on a Mac.  There is some better Facebook integration and a security tool dubbed Gatekeeper which is Apple's stab at having security.  It just flags when you are about to install something.

All up a big yawn, but will distract users from bad press caused by the fact that the iPhone 4S did not sell as well as expected.
