Apple developers tested the Mavericks Mac OS X 10.9.3 Beta and decided to add in a better 4K Ultra HD support and include “Retina Display”.

Upgrading the Retina

Right after the implementation of Apple’s Retina display in MacBooks, they soon optimized Mac OS X systems to support it as well. What it mainly does it that it supports different scaling to get the best display and prevent having text too small or too delicate at higher resolutions.

 Flaws that were fixed

Before the implementation of this technology, if one used an Apple system on a 4K monitor, the texts sometimes appear illegibly small and difficult to read and sometimes the resolution can’t be set to highest like in  the case of Sharp’s 32” 4K display can only be set to 2560×1440 max. And one more depressing fact that hindered 4K output is that the rendering of MacBook Pro Retina screen is same as implemented in 4K so the UI elements, menu and other small elements are extremely inconvenient to identify.

Features added

After the improvising the 4K support, the device can utilize full native resolution and different zoom levels like 2K to 4K resolution display. And after testing the end version of 2013 present in the new MacBooks pro and Mac Pro using Dell’s Ultrasharp 24-inch 4K displays are rendered perfect. The max refresh rate supported in the updated version is 60 Hz rather than 30 Hz and 24Hz using DisplayPort interface and HDMI respectively.

After this one may expect Apple to launch 4K display Thunderbolt interface, can we expect Apple cooking that up?
