    Did your iMac have a kernel panic? http://support.apple.com/kb/TS3742

    If so you should be able to copy and paste the panic log here and we can take a look at it http://support.apple.com/kb/HT2546?viewlocale=en_US

    Or you can ignore it for now. If it never happens again don't worry about it, but if it continues to panic you need to find the cause.

    When shut down and rebooted, the Mac OS X does background maintenance on the system. That can solve minor issues.

     

    Beyond this, it is a good idea to run Disk Repair yourself just to make sure.

     

    Reboot with the option key held down. On the screen that comes up select the Recovery disk icon and Continue.

    On the next screen Clcik Disk Utility and Continue.

     

    In DU, in the list on the left select the drive to be repaired - click the item that is indented to the right, not an an item whose name starts on the far left.

     

    Click First Aid, then Repair Disk.

     

    After that is done, quit DU and restart as usual.
