Apple has reportedly just about wrapped-up development of Mac OS X 10.5 Leopard as sources claim a 26 October release of the new OS.
The company is also developing a final maintenance and security update for Mac OS X 10.4, which offers Dashboard enhancements.
Apple has also begun training up its support teams in the way that Leopard works, a report explains.
Piper Jaffray analyst Gene Munster recently predicted the release of Mac OS X 10.5 will generate $240 million in the fourth quarter of 2007.
