Apple posts OS X Mavericks Developer Preview 4

Apple on Monday posted a new build of OS X Mavericks to the Mac App Store, accessible to registered Mac developers who are currently using Mavericks on a test machine. No details were posted - all Apple indicated was that the update is recommended for all users running OS X Mavericks Developer Preview 3.

With the Mac Dev Center down in the wake of last week's security intrusion, the Software Update system preference appears to be the only way to get the new release.

OS X Mavericks was introduced at Apple's Worldwide Developer Conference (WWDC) in June. The new release of OS X, coming this fall, introduces key new features like Finder Tabs, Maps and iBooks, iCloud Keychain, improved multiple display support and more.

Are you looking forward to Mavericks' release this fall? What features excite you the most? Tell me in the comments.

  • I will update if it is free. Looking for enhancement when working with some app/windows.
  • Free? Mavericks isn't likely to be free, it's a whole new version of OS X, which has never been free
  • Agreed. I don't see it being free, but I don't see it costing much either. Sent from the iMore App
  • It won't be free I can tell you that right now. LOL It won't be expensive either.... No more than like $30, if I had to guess?
  • If past is prologue, $19.99.
  • I look forward to it. I am hoping to see some refinements in areas I dislike about OSX. As long as they don't give it the look of iOS 7, I'm good. Sent from the iMore App
  • Fortunately for you, there's no evidence that they're radically redesigning the user interface in an iOS 7 way.
  • I'm excited for the battery saving features.
  • Quite frankly, all of 'em. New to OS X and really enjoying it. So the additions plus improving the old is great. Looking forward to having iBooks as an option on the desktop. Everything else will be be a bit of a learning curve. Sent from the iMore App
  • I will update for user.
  • I am beyond excited about this update! I just bought a fairly new MacBook Pro (2011 model) about a month ago. Coming from a White 13-inch Macbook which wasn't even upgradable to Mountain Lion, I am stoked to be able to run ML and now Mavericks, soon. I am excited about every single feature! Hurry up, Fall!!! :D
