We have a Macbook Pro 15 Last 2011. The computer starts to boot, it shows the progression bar, then it disappears and the circle just spins.
I have tried safe mode and it just spins.
I just ran the hardware test and it returned no problems - I am trying to boot into safemode now
This screen has been running for 15 minutes now - Eventually the grey bar disappears and it just spins
EDIT:: I booted in startup mode and chose the disk utility - It said the HD was fine :(
EDIT:: I am able to boot from a external thunderbolt drive
Ran in verbose mode. Last couple of lines after rebuilding b-tree:
The volume Macintosh HD could not be repaired launch_msg(): Socket is not connected
