Apple's OS X Mavericks Developer Preview 3 Now Available
Along with iOS 7 beta 3, Apple has made OS X Mavericks Developer Preview 3 available to download for registered developers. The third prerelease software update, which launched two weeks after OS X Mavericks Developer Preview 2 became available, appears mainly to contain bug fixes and performance improvements for Apple's forthcoming Mac OS X update. Here are the release notes:
Installation:As a reminder, Apple is adding a built-in Maps app, Finder tags and tabs, battery life improvements, and a faster Safari Web browser in OS X Mavericks, which will launch later this year in the Mac App Store. More than a handful of these features are indeed taken from the company's mobile operating system, in a move which continues the trend Apple established a couple of years ago with its "Back to the Mac" event. We'll keep you updated with further information on OS X Mavericks as we receive it.
