Looking to tame Apple's Mountain Lion? Step right up, Cupertino's latest build of OS X is ready for consumption -- assuming you're a registered developer, of course. Following WWDC's reveals and teases, Apple has released an updated preview of its desktop and mobile operating systems, serving up Mountain Lion Preview 4 and an iOS 6 beta to developers. The rest of us will have to console ourselves with iTunes 10.6.3, which adds support for the mobile and desktop OS' those fancy devs are getting their hands on. Don't worry, the updated music management software will be able to make full use of Mountain Lion next month, but you'll have to wait until this fall to sync with iOS 6.
