Hey, as I own a nMP, and we've had all these endless discussions about 4k support in OSX, does Yosemite bring ANY improvement to the table? I mean, ok yes we now have retina support for 4k displays in the old fashioned rmbp way. But what about UI scaling? There seems to be no improvement whatsoever.. ? So we're not getting a 4k display from apple this year I assume?
