OS X Mavericks 10.9 Developer Preview 3 Available for Download

Apple seeds OS X Mavericks Developer Preview 3 for Mac users. Continuing its two-week release cycle, Apple released the third developer preview version of its next-generation Mac operating system. OS X Mavericks Preview 3 offers multiple but minor changes. Developer Preview 3 is now available to download via the Mac App Store for those who are eligible for such an update.

According to the release notes, the update brings with it likely stability and performance improvements just like the latest iOS 7 beta 3, which was released a few hours back. Apple also mentions some known issues as well as some fixes that were included within the release.

These changes refer to the way how Maverick handles the forthcoming iCloud Keychain feature as the seed is not backward compatible with iOS 7 Seed 2 or Mavericks Developer Preview 2. In this respect, users will have to re-enable iCloud Keychain from the iCloud preferences pane after upgrading to Developer Preview 3.

Other known and notable changes include graphics problems when resizing or switching from standard to satellite view in Maps, file handling, in Aperture and Photoshop, and other various small bugs. In the final part of the release note, Apple points out that Fusion Drive volumes created in Developer Preview 3 are incompatible with OS X 10.8.4 or earlier.

OS Maverick 10.9 is the latest Mac operating system released by the Cupertino-based company, and it will be made available to the public later this year. The upgrade will bring a high number of improvements and feature additions to the current OS X 10.8 Mountain Lion including Finder Tabs, Maps, App Nap, Compressed Memory and many others.

As Apple has suggested, the new improved operating system will bring vastly improved battery life as well as new iBooks app, improved multi-monitor support and an overall improved experience.

If Apple continues with its release cycle, the most likely is that OS X Maverick 10.9 Developer Preview 4 will be released some time two weeks from now.

Developers can download the third Maverick Developer preview via the Mac App Store. Those running OS X Mavericks Developer Preview 2 can find the new update available in the Mac App Store, via the Software Update menu.

On the other hand, for those who are not yet running Mavericks, but own a registered developer account, the full installer can be downloaded from the App Store, and then found in the Applications directory. Moreover, the installer app can then be turned into a bootable USB install drive if desired.
