Apple Seeds New 13A598 Build of Mavericks to AppleSeed Members

Apple has seeded a new release of OS X Mavericks to members of the AppleSeed beta testing program, a little more than two weeks after the release of the eighth Developer Preview. DP 8 had a version number of 13A584, while today's release is build 13A598.

Separately, 9to5Mac reports that this build may be a GM candidate, according to AppleSeed members, while other sources have said the final release build will be several versions newer. The OS was reportedly nearly ready for release a few weeks ago, but was pushed back because of "critical bugs".
Since being announced at WWDC, OS X Mavericks is said to have picked up a few minor unannounced features. Namely, the Messages and FaceTime applications have received the ability to block phone numbers and Apple IDs from sending the Mavericks user messages and/or FaceTime calls. This addition brings parity to iOS 7 and the two operating systems will sync in this manner.
OS X Mavericks, which is expected to be released this fall, includes multiple new features like a tabbed Finder, full screen dual monitor capabilities, Safari improvements, and a new Maps app.

Apple is reportedly targeting a late October launch for OS X Mavericks.

i couldn't have been less excited about a release of a new OS.
block calls? useful for a phone but to me, not so much in my computer.
tabbed finder? nice but don't need.
full screen dual monitor? don't have two monitors.
safari improvements? ditched that in favour of chrome a while ago.
maps app? lol no thank you.
i'll be keeping ML which works great.

weird that they're not seeding it to devs yet.

I'm glad OS X 10.8 Mountain Lion is still getting attention. I think I'll wait a few months for any initial bugs to be ironed out and then upgrade to OS X 10.9 Mavericks.

Does this version include a finalised GUI for Notes and Game Center yet? Also I think maybe Contacts was due for revision too..


I imagine that Mavericks is really just a stop-gap for the time being, with regards to U.I design. It's inevitable that Apple will release an iOS 7 inspired successor next year, and providing the changes are carefully tuned, then I for one can't wait.

I wonder if they fixed the finder issue in mountain lion

----------

I agree, but I love tabs in Finder, but use TotalFinder. But there are a countless "under-the-hood" improvements that I am looking forward to.


Snow Leopard was the best ever and still is.
