Ondrej Holzman Apple has prepared a very welcome novelty in the first beta version of the operating system OS X Mavericks 10.9.3 (OS X 10.9.2 was released last week), which will be especially welcomed by owners of 4K monitors. Apple will finally offer resolution scalability, and 4K monitors connected to Macs will be able to natively run at twice the "Retina" resolution. This will ensure a much sharper image.
Changes in the ability to adjust the resolution should appear to users of MacBook Pro with Retina display (Late 2013) and, of course, also to owners of new Mac Pros. Up to three 4K monitors can be connected to this computer at once, but until now Apple's support for such resolutions has been spotty.
On its Apple Store, Apple offers a 32-inch 4K display from Sharp for the Mac Pro, but when you connect it to the Mac Pro, only a resolution of 2560 × 1600 pixels is supported, and Apple also renders text and graphics the same as on the Retina MacBook Pro, which results in means very small and hard to read elements on a giant display. However, this was not the case only with the model from Sharp, the support for 4K monitors in Mavericks was simply not good.
OS X 10.9.3 should definitely solve this burning problem, because it will be possible to double the resolution on the same surface, i.e. display twice as many pixels. It is also speculated that with this move Apple is preparing to introduce its own 4K monitor, which it still lacks in its portfolio. That is why we can find a Sharp product in the Apple Store.
OS X 10.9.3 reportedly enables 60Hz 4K output for Retina MacBook Pros from 2013. The higher refresh rate, which no older Mac can offer besides the Retina MacBook Pro and Mac Pro, will ensure a better viewing experience, especially useful when editing video or playing games .
especially let them finally solve the sound, it's really crazy on iMac late 2010 and everything is ok on MB Air 2012..
OS X Mavericks is shit
Your mom is a piece of shit.
