Apple today seeded build 13C39 of OS X 10.9.2 to developers, marking the second developer beta iteration of 10.9.2. The release comes almost a month after the first OS X 10.9.2 beta, build 13C32, was seeded to developers.
The first seed of OS X 10.9.2 introduced FaceTime Audio to the Mac and asked developers to focus testing on Mail, Messages, VPN, Graphics Drivers, and VoiceOver. The second build allows Mac users to block people on iMessage and FaceTime as can be done in iOS 7.
Apple has also seeded Safari 7.0.2 for Mavericks and Safari 6.1.2 for Lion/Mountain Lion, asking developers to focus on General Website Compatibility, Accessibility, AutoFill features, Printing and Emailing from Reader, Dragging Tabs Between Monitors, and Extension Compatibility.
