I updated to Yosemite on Saturday and everything has been working fine, I have been able to shut down and startup as normal until today.
A couple of days ago I forced my Early 2011 MacBook Pro to shut down and now it will no longer get to the login screen.
I hear the chime, the Apple appears with the Yosemite status bar underneath, it takes a long time to get about halfway then both the Apple and status bar disappear leaving just a blank grey screen.
- I can get into Single User mode, using "fsck -fy" it reports that everything is OK.
- I can't get into Safe Mode, I just get the Apple and status bar followed by grey screen
- I have reset PRAM
- The Internet Recovery globe and status bar appear followed by the Apple and status bar then grey screen
- Holding Option I can select my disk but there is no Recovery Disk displayed. The image of my hard drive that appears has a custom icon that I haven't used for at least 5 years which is very odd indeed.
- I have a bootable Yosemite USB, holding option I can select that but it just brings up the Apple and status bar then grey screen.
So basically everything other than Single User mode ends up at a blank grey screen.
I'm at a loss, any help would be greatly appreciated.
NOTE
My left fan is faulty, I have ordered a new one online. I have been using SMCFanControl to monitor it, if the computer has been feeling hot I have been increasing the RPM for a minute to cool it just to be safe until the new fan arrives. Last night I increased the RPM and SMCFanControl became unresponsive which is why I forced the computer to shut down because I couldn't reduce the fan speed back to normal.
