Hey Everyone, this is a fun one. Apple's 2011 Edition Macbook Pros had this awful underlying fault with the AMD GPU (graphic card) that caused it to fail, and thus your Mac wouldn't boot. It was such a prevalent problem that Apple issued a recall, but in classic Apple fashion they only "fixed" it if you experienced the failure, actually they only replaced the logic board with another having the same underlying GPU fault -- just to buy time to get out of the warranty period. Thanks Apple.
What the problem looks like:
Here's the Fix:
At this point the Mac will restart twice. First, it will run a bunch of text past, this is normal and will only happen once. It will chime and reboot again and run different text past, this is also normal and will happen on every reboot (it's quick). Finally, the Apple logo will appear and the boot will finish. Your mac should work normally now.
If you want to disable the verbose mode (scrolling text at boot) after you've verified the fix is working do this:
