Apple Releases New Beta Builds for OS X Mavericks 10.9.3 and iTunes 11.1.6
Apple recently seeded the latest betas of OS X Mavericks 10.9.3 and iTunes 11.1.6 to developers for testing with the new software marking a return of contacts and calendar data syncing in iTunes. The latest OS X Mavericks 10.9.3 build 12D21 comes one week after the last beta was seeded and Apple is once again asking developers to focus on graphics drivers and audio enhancements.
One of the features in both OS X Mavericks 10.9.3 and 11.1.6 betas is the restoration of iTunes syncing for contacts and calendar data over USB and Wi-Fi. This was a feature deprecated from the current version of iTunes in favor of Apple’s iCloud solution. Combined with the latest iTunes 11.1.6 beta, developers can sync contact and calendar data on an iPhone, iPad or iPod with a host Mac.
An earlier seed of OS X Mavericks 10.9.3 revealed that Apple is planning to enable a so-called “Retina” output mode for users connecting their late 2013 MacBook Pro with Retina display to external 4K monitors. The feature can be described as a pixel-doubling scaling option that is capable of displaying a desktop at native “Retina” levels over HDMI. Current Retina MacBook Pro owners that are running OS X 10.9.3 are limited to a maximum scaled resolution of 4,096 pixels by 2,160 pixels at 24Hz with a refresh rate being capped at 30Hz for lower resolutions. With the upcoming update, output to a 4K display is expected to achieve 60Hz while pixel-doubling.
Developers can download the new beta builds from Apple’s Developer Portal or via Software Update.
