To go along with Apple’s release of iOS 7 beta 3 earlier today, Apple has also released the third developer preview of its desktop operating system, OS X Mavericks. The update, which comes in at just a hair over a gig, touches down two weeks after the second developer preview.

I’ve already installed DP3 on my test partition, and I haven’t noticed any drastic changes thus far in my usage with it. Check out the release notes inside…

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 3.
  • Reinstalling Developer Preview 3 from the Recovery Partition is not supported. Developer Preview 3 can be reinstalled using a Time Machine backup or Target Disk Mode.

iCloud and iCloud Keychain

  • The Reset Keychain button in Account Details of the iCloud preferences pane is for testing purposes and will not be available in the final release.
  • First-time iCloud setup may fail. Disabled services may be enabled manually in the iCloud preferences pane.
  • After upgrading to Developer Preview 3, iCloud Keychain will need to be reenabled in the iCloud preferences pane.
  • iCloud Keychain in OS X Mavericks Developer Seed 3 is not backward compatible with iOS 7 Seed 2 and OS X Mavericks Developer Seed 2.
  • Third-Party Applications
  • Installation within a virtual machine is not supported for VMWare Fusion.
  • Adobe After Effects CS6 will not function correctly.

Other

  • Screen recordings taken with Developer Preview 3 are not compatible with earlier releases of OS X.
  • The QuickTime Player progress bar may be nonfunctional when opening media that requires conversion prior to playback.
  • Aperture may exit unexpectedly when exporting an image while in full screen.
  • 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.
  • When saving from Photoshop, Save As may not respect the selected file type.
  • Fusion Drive volumes created with Developer Preview 3 are not compatible with OS X v10.8.4 or earlier.
  • Developer Preview 3 includes OpenSSH 6.2p2.

If you’re an Apple developer, then you may head over to the developer portal to download OS X Mavericks Developer Preview 3. If you’re already running any of the previous Mavericks Developer Previews, then you can use the update found via the App Store app instead.

    The photoshop save issue exists on the first beta and beta 2, wish I never upgraded to the beta in a way

      To be honest, I am running a Hackintosh machine, which works great on Mountain Lion. I took a look at 10.9 but it was full of bugs which brought me back to 10.8. I won’t be testing it anymore, wait for the final release.

      I’ve personally not experienced any bugs and I have use both iCloud keychain and Photoshop and the like. I’ve only ever experienced the odd app window crash.

    It’s much better waiting until RC or Final Released… there to many bugs on Developer Preview :|
