Nearly one month after the initial seed, Apple has provided developers with a second beta release of the upcoming OS X 10.9.2. The new build is labeled as version 13C39, and it is available via both Software Update in the Mac App Store for those running the first beta and from Apple’s online developer portal. The first 10.9.2 seed added enhancements to both the Messages and FaceTime applications, allowing for FaceTime Audio calls. Apple has added the ability to block people on iMessage and FaceTime with this new seed. The blocking mechanism syncs with blocked contacts on iOS 7. Blocking, according to people familiar with this update, is available in the preferences tabs for both the Messages and FaceTime apps.  Thanks, K!
