Apple is widely expected to release OS X 10.9 Mavericks at the end of October. Anonymous sources indicate Cupertino will more than likely stick with tradition and launch the software the day after their fourth quarter earnings announcement.

The company first unveiled Mavericks during their annual developers conference back in June. A preview version of the non-cat-named software was given to developers with the promise of a general release coming sometime this fall.

Chief among the changes in Mavericks are finder tabs and enhanced multiple display support. As the name suggests, finder tabs is a browser-like tabbed environment designed to replace the multiple finder window. From here you can drag and drop between tabs and even expand it to full screen.

Multiple display support, meanwhile, brings the operating system up to level standards with Windows. Craig Federighi, Apple's senior vice president of software engineering, said during the presentation at WWDC that users will now be able to access menus across multiple displays and activity on one monitor won't mess with activity on another.

Elsewhere, the software is said to feature reduced power state transitions that cut down on CPU activity by up to 72 percent. It's also capable of compressing inactive memory to free it up for other applications. Overall, Mavericks is said to include more than 200 improvements.

The most recent update to OS X came in the form of Mountain Lion back in July 2012.
