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.

1092
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.

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.

Definitey Ive should be demoted to hardware-only designer. iOS 7 is just plain ugly. His too-thin devices (iPhone, MBPr, mini, iMac) suffer from loss of function due to thinness.

Do go on.

Yes his position must now be untenable with such poor sales and take up of his recent designs.

Oh, no, wait a minute...

here's hoping that apple is paying attention to all the p***ed off users who are howling about them pointlessly removing things like 'open folder in new window' as an option and the ability to tag folders & files with coloured lablels (not near-invisible dots) and they reinstate these long-standing features in one of the updates.

i want to murder those dots.

MacBook Pro Retina 15" (Late 2013) NVIDIA Driver Update Please!

I've got my fingers crossed for an updated NVIDIA GeForce GT 750M driver to support 3840 x 2160 (60MHz) monitors via the Thunderbolt 2 port.

Update: I think what is also required is to have support for DisplayPort 1.2’s Multi-Stream Transport (MST) enabled.
