Apple Seeds First OS X Mavericks 10.9.3 Beta to Developers

by

Apple today seeded the first test build of OS X 10.9.3 to registered Mac developers, just over a week after releasing OS X 10.9.2. The new beta, which has a build number of 13D12, is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple is currently asking developers to focus on Graphics Drivers and Audio, and there is no word yet on specific fixes and changes included in the update.

The last Mavericks update, OS X 10.9.2, added FaceTime Audio, the ability to block iMessage users on the Mac, and a fix for a critical SSL vulnerability. 10.9.2 saw a beta testing period of approximately two months, and it is likely 10.9.3 will also see several beta iterations before a public release.

Mavericks has been the worst upgrade experience for me. Lion was a walk in the park compared to this 10.9 sh**!

I'm on 10.9.2 and I'm fed up with the crazy beach balling, slooow as molasses Finder, audio issues, and wifi issues. Rebooting temporarily fixes the audio and wifi issues.

I've started looking into rolling back to Mountain Lion. OS X 10.9 and iOS 7 needed more time to bake. I'm not impressed with Apple at the moment.

What Mac do you have? I have none of the issues and Mavericks is pretty much the best OS X release since Snow Leopard for me.

Short lived....

the SSL fix should of be separate of 10.9.2 after they fixed it.... Whats 24 hours ? its a long time to stay vulnerable.

SSL fix one day, 10.9.2 the next..... :eek:

My guess would be 10.9.3 would bring MORE stuff from iOS....

Makes you wanna go back to Mountain Lion doesn't it ?

I think this is more of Apple changing how OS works, gone are the days mobile and desktop features were separate... Now, they are all in one..

I wonder what would have happened if Microsoft started introducing Google/Android features in their OS

This is the biggest pile of crap I've ever read!

10.9.3 will not turn OS X into iOS! Apple have stated they have no intention of merging the two!

And no it doesn't make me want to go back to the mess that was Mountain Lion! Mavericks is far superior.

really? I just am not seeing those kind of issues with my mbp.

Me neither. Mavericks is far superior.

I saw the push notification from MacRumors and my knee jerk reaction was that iOS 7.1 was out. :(

This is still good news though!

On that note, push notifications are amazing.
