Apple has seeded the eighth Developer Preview of OS X Mavericks to developers, nearly two weeks after the release of the seventh Developer Preview. Registered developers can receive the update via the Software Update tool in the Mac App Store.

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.

Update: As noted by 9to5Mac, Developer Preview 8 includes an updated version of iTunes 11.1 that adds an option to turn off song change notifications.

549 MB update thru the App store. :)

No seed notes in the dev. center.... yet [ as of 5:23 pm Mountain Time ]

Build : (13A584)

Notes and Known Issues


- 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 requires Windows Migration Assistant, available from the Mac Dev Center.


- 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.
- Purchased music may not show cover art in Preview. To resolve, run the following command in Terminal: qlmanage -r cache

Hopefully my Mail crashes and freezes have been fixed...drives me nuts to have to force quit almost every hour.

I don't, but Mail have to be restarted every now and then - it just doesn't update after a while.

Added more 27" Retina wallpapers .... interesting...

So a Retina iMac:apple: or a Retina TB Display is on the way...

Pardon the question, but how can a wallpaper be 27"....?

I guess you meant the resolution is double of 2560x1440, which with apple mean a 27" monitor? :)
