Apple Released the OS X Mavericks Developer Preview 7

Apple is moving steadily forward on OS X Mavericks, releasing the Preview 7 version to developers today nearly three weeks after the release of the sixth Developer Preview. The new preview doesn’t have any notable feature additions but includes a few extra wallpapers and a link to a new OS X Mavericks page that is not fully live, yet. Registered developers can receive the update via the Software Update tool in the Mac App Store.

The new release points to a new Mavericks website detailing the new features.

iCloud and iCloud Keychain

iCloud Keychain users will be prompted to reenable iCloud Keychain after installing Developer Preview 7. 

Installation

Network migration from earlier versions of OS X requires the Migration Update for Snow Leopard, Lion, or Mountain Lion, available from the Mac Dev Center.

Migration from Windows is not supported in Developer Preview 7.

iBooks

PDFs imported into iBooks in previous seeds of OS X Mavericks may be renamed when opened with Preview.

Other

Screen recordings taken with Developer Preview 7 are not compatible with earlier releases of OS X.

Fusion Drive volumes created with Developer Preview 7 are not compatible with OS X v10.8.4 or earlier.

Moving a full-screen Aperture window to a secondary display may prevent the app window from being visible in subsequent attempts to use full screen.

In Full Screen in Aperture, some menus and thumbnails aren’t immediately available until interacted with by the user.

When in Full Screen in Aperture, the toolbar at the top of the window may not be usable until it is locked.

Starting in Developer Preview 4, non-admin users will be allowed to install and update software from the Mac App Store. This functionality can be disabled with a profile that sets the “restrict-store-require-admin-to-install” key to true (boolean) in the com.apple.appstore domain.

The new released seventh developer preview of OS X 10.9 Mavericks includes eight beautiful new wallpapers. The new wallpapers depict various landscapes including a scenic mountain view and yet another oceanic-themed wave. Check out our gallery below and try out the new Mavericks wallpapers for yourself!

Called as “a bag of hurt”, Blu-ray has always been die-hard trouble for all the Mac users. Every updates and release events brought great surprise, as well as one more time disappointment. The Blu-ray playback capability is what we need urgently and hope to find even from the third party software. According to some reviews from authoritative websites such as Macworld and Tuaw, we could figure it out that Mac Blu-ray player out of Macgo tops the list. It is the first Blu-ray player software for Mac in the world and already accepted by a large number of Apple fans. All Blu-ray Disc, Blu-ray files, and Blu-ray folders (BDMV folders) can be perfectly played on MacBook Pro, Air, Mac mini, iMac, Mac Pro with OS X 10.5 to 10.8, even the latest Mavericks. What great news!

Updates to the Mavericks beta have been pushed out systematically over the summer, and Apple will ship the OS to the public this fall. The September 10th event will focus on iPhones, and a separate media event is expected to take place next month. Apple could release Mavericks at any time this fall, but it’s likely that a release date will be given alongside new iPad/Mac hardware in October.
