My MacBook Pro OS X Version 10.10 keeps crashing ~ HELP! [duplicate]
Your GPU is dying. Only a replacement plan from Apple can help you. But I doubt that it is near. At least you are not alone ;-). https://discussions.apple.com/thread/4766577?start=9495
And now there even is an extended warranty program: http://arstechnica.com/apple/2015/02/apple-launches-repair-program-for-longstanding-2011-macbook-pro-gpu-problems/
You can get to a more or less workable state by reverting back to Mavericks using a backup and then disabling the kernel extensions that are needed by the GPU:
It will force the system to use Intel HD 3000 Graphics. But at least you can boot, do some work and / or recover files. Reboot your computer and hold CMD + S, and type and press enter the following commands:
- /sbin/mount -uw /
- mkdir /System/Library/DisabledExtensions/
- mv /System/Library/Extensions/AMD* /System/Library/DisabledExtensions/
- mv /System/Library/Extensions/ATI* /System/Library/DisabledExtensions/
- Reboot by typing 'reboot' and enter.
If you need to restore the drivers:
- Boot normally, and from OSX open a Terminal window.
- sudo mv /System/Library/DisabledExtensions/* /System/Library/Extensions/
- sudo reboot
Downsides:
- Can't adjust screen brightness;
- Machine won't sleep. Need to shut it down before bagging it;
- Can't adjust any external display;
- Graphics performance is CPU only, so it's quite slow.
Apple has a helpful article on Kernel Panics which is what you appear to be experiencing:
- http://support.apple.com/kb/HT200553 - OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem."
I would step through that and post back here a new question once you have a specific step that is failing or you don't know how to proceed in that checklist of things to do.
