The final Apple Mac OS X Mountain Lion 10.8.3 update is now available on pre-release on the Apple Developer Connection. Reports are filtering out that this is the final build before it is made available to the public.

This means that the next update to Mac OS X Mountain Lion (which takes us from 10.8.2 to 10.8.3) will be available to the public shortly, hopefully within the next week or so. As with all updates to Mac OS X we expect it to be made available via Software Update.

The build, marked Build 12D78 (Pre-Release), is the latest, and unless any major problems appear, the final build before release.

The most recent Mac OS X build was released last week on 6 March and asked developers to focus on "AirPlay, AirPort, Game Center, Graphics Drivers and Safari." It would appear that these issues have been solved and that Apple now considers it ready for public release.

We've been expecting an update to Mac OS X since January, although some people are speculating that the update has been held back because Apple wishes to keep some features related to iOS 7 secret.

Speculation suggests that Apple may be considering the name 'Lynx' for its next Mac OS X, 10.9, which is expected to be released later this year. The new operating system could introduce Maps and Siri integration to the Mac, reports say.

OS X 10.9 has been appearing in analytics logs across the web, and it is expected that Apple will launch the operating system around July 2013, possibly at its Worldwide Developers Conference (WWDC).
