I recently upgraded my software to El Capitan on my MacBook Pro. It worked fine when I did the update. I came home a few days later and had a folder with a question mark on the screen.
I then turned the power off and restarted while holding Command R to restart in recovery mode.
Now all I get is a screen with the apple logo and it gets stuck loading about 3/4 of the way through. It eventually comes up with a screen stating "launch failed and your computer is restarting because there was a problem" It just keeps doing this over and over....
What can I do?
Straight to apple care?
There is also a clicking noise coming from inside the computer as well... What is this?
MacBook Pro with Retina display, OS X El Capitan (10.11)
