    I have a 2014 mbpr that I purchased in July. I recently installed Yosemite beta 3 and right after it installed the Mac refused to boot. You hear the boot sound and the screen stays black but the back light is still on. I tried pram reset and Some other reset but still cannot get the fraking thing to boot. Does anyone have any ideas or do I have to visit the Apple store. Thanks in advance
