I’m using MacBook Pro with Retina Display, Mid 2012. Partition is not changed, Volume label is ‘Macintosh HD‘.
I was trying to wake my macbook pro up in airport, the monitor was not lightened. Then I forced shutdown and reboot, monitor was still dark. I tried a lot, not work.
I thought I should reset PRAM, after that I saw the apple logo with gray progress bar, running to 20% at most, then computer shutdown.
UPDATE[2014-10-11]: One of my friends met the same progress bar, but resetting PRAM works for him.
