Runs native on a Mac?

I saw that the udk runs on mac too - fantastic - but only from 10.9.2 up?
why is this so - can i try to run it on mac with mountain lion 10.8.5 ?
my system runs so smooth and all is working perfect so i don’t want to change to another system.

i have a 12 core and external 4 x GTX titan 6GB and on sytem a GTX 680 4 GB
that normaly be enough power - or?

best regards

On Mac OS X UE4 requires OpenGL driver updates that are only available in 10.9.2 and later. The current version of OS X (10.10.1 as of this writing) is strongly preferred as this contains even more OpenGL improvements that UE4 benefits from.
