Apple Seeds OS X Mavericks 10.9.2 Build 13C53 to Developers

by

mavericks.pngApple today seeded build 13C53 of OS X 10.9.2 to developers, marking the fifth beta iteration of 10.9.2. The release comes a week after the fourth OS X 10.9.2 beta, build 13C48, and over a month after the first OS X 10.9.2 beta.

The update is available to registered developers through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple continues to ask developers to focus on mail, messages, graphics drivers, VoiceOver, VPN, and SMB2. Earlier betas of OS X 10.9.2 began allowing Mac users to block people on iMessage and FaceTime, as can be done in iOS 7, and also introduced FaceTime Audio.

Just installed.

On the plus side, UI performance on my Unibody A1342 MacBook has sped up considerably (was getting Launchpad lag on the previous build) and my CPU and GPU temps have come down quite a bit along with RAM usage.

I am however getting audio interference on my external USB speakers where there was none before.

Am I the only one waiting for graphics performance bump to what we saw in DP6-7? Right now the OpenGL performance is lower than that by 35-50%, which is definitely NOT normal.

They messed up core audio too still when going from 10.9 to 10.9.1

It's a HUGE issue for anyone using any external audio interface!

So far all the betas have made the issue much worse, and it's unusable for any professional or amateur use.

I don't understand why apple has messed with the sound part of the OS code it makes no sense considering any audio app should be auto excluded from it anyway.

What problems do you have?
I'm not having issues with the beta's and I've been doing recordings with external cards. Not Core audio though, dedicated drivers..
