Hi,
On the most recent Yosemite update, after installing and restarting my laptop, my 2012 MBP Retina will only boot to a black screen. When I turn on my laptop, the screen illuminates black and I hear the chime sound, but nothing is displayed in the screen. I've tried using all of the boot key commands and nothing seems to work.
I've even tried using an external display using the HDMI port, but it outputs no signal.
Does anyone have any advice?
