Apple seeds OS X Mavericks Developer Preview 7

OS X Mavericks DP4 Setup

Apple has seeded the seventh developer preview of OS X Mavericks this afternoon. The download comes nearly two weeks after Developer Preview 6 was released, which didn’t carry any significant new features.

The newest Mavericks preview is now available for download in either the Mac App Store, as a software update, or through Apple’s Mac Dev Center, to all registered developers. More details after the fold…

There doesn’t look to be any major new features in DP 7, but we are currently installing it on our machines and will be sure to report back with anything of note. In the meantime, here’s some release notes (via 9to5Mac):

  • iCloud Keychain users will be prompted to reenable iCloud Keychain after installing Developer Preview 7.
  • 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.
  • PDFs imported into iBooks in previous seeds of OS X Mavericks may be renamed when opened with Preview.
  • 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.
  • New default wallpapers to choose from

Apple first introduced OS X Mavericks at WWDC in June. It will be available to the public this fall, bringing along a number of new features including Maps and iBooks apps, Safari improvements, and much more.
