Q: Macbook Pro hangs when booting
Hey there fellow Apple Users. . .
I have a Macbook Pro 8,2 (Early 2011) that has recently started acting up. This has been a solid machine for the 4 years I've owned it. It was purchased as a refurb unit.
Anyhow a few day ago went to bed and left the computer rendering a project in iMovie 9.0.9 In the morning I woke to a gray screen and the fans were running. I tried to reboot and the progress bar made a third of the way and then switched to a gray screen and then the fans started running fast. I rebooted again a few times sometimes it just sat there at the gray screen sometimes it restarted on it's own but it never got past the gray screen.
So far I've accomplished the following:
Booted into Single User mode and run fsck with no errors detected.
Copied the internal hard drive to an external drive.
Determined the movie had finished rendering. The final file was saved to my desktop.
Poked around the log files but haven't found any clues as to what broke.
Booted from Internet Recovery with the same result.
Booted from an external Rescue drive with the same result.
Booted with the Apple Hardware Test which reported no trouble found.
Anyone have a suggestion about what else to try?
Thanks!
MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10.5), null

Many of the 2011 models show problems with the graphics processor after a couple of years. Have your MacBook checked for that: there is a free extended repair program for this.
