Apple rolls out another OSX 10.9.3 Beta

Apple recently rolled out another beta version for developers of its OSX 10.9.3 operating system, close to a week after a first version release was launched.

As with most OSX beta release versions, the second installment came with enhancements and functional add-ons that were missed out in the first – this time, focusing on enhanced graphics and video-related enhancements.

Based on the testimonies of beta testers/developers, the Cupertino-based company is noted to have made requests delving into testing the beta OS’ video and graphics rendering features and performance-based capacities. Enhancements touching up on the OS’ audio drivers were also included in the latest beta release.


Since the previous beta – OSX 10.9.2 – did not come with features that supports pixel-doubling, the new update covers the graphics-related spaces that were left out. At its core, the new beta update comes with heightened support for more than 4096 x 2160 @ 24Hz screen resolutions, which essentially translates to support for 4K screens or monitors.

Dubbed the “Retina output mode”, the update features a double scaling option for display outputs via HDMI, saying something about how forward thinking Apple is in the implementation and application sides of its new operating system.

Reportedly, the new beta can support 4K displays at a 60Hz refresh rate, and this rating is attributed to be laggy or choppy in terms of actual graphics rendering and performance.

However, since it is still a beta, it can be expected that this aspect of the OS is sure to be ironed out before it is officially released to the end-user segment.
