Good morning all! I've tried to do some research and while I did find some information about command-r on the reboot, I didn't find anything on what exactly is happening to me. So my computer has been running slow, so I opened up Disk Utility and pressed Verify Disk. After it completed, it told me that the volume was corrupt and to restart the computer and hold down command-r until the Apple logo appears. I did this, and once I let go, it would continue to think for about 10 seconds and then my computer shuts down, and the disk utility never opens. Any ideas on what's going on and how to fix it? Thanks!
