iBooks for OS X Mavericks (Multiple books)

Apple has seeded the fifth OS X 10.9.2 beta to registered Mac developers this evening. The last few beta releases have each come about a week apart, suggesting that they’re nearing a final version.

The new build is available to registered Mac developers through the Software Update tab in the Mac App Store, or as a full download via the Mac section of Apple’s online developer portal

There’s no word so far on what specific changes are coming in the update, but Apple has asked developers to focus on Mail, Messages, graphics drivers, VoiceOver feature support, VPN and SMB2.

The first beta, released in December, added support for FaceTime Audio in Messages and FaceTime apps. Today’s build is labeled as 13C53, and we’ll be sure to let you know if it offers anything new.
