When I press the desktop and screensaver is absolutely nothing happens. The "loading pictures" states the computer, but nothing shows up. What's wrong? I have tried restarting the computer.


iMac, Mac OS X (10.7.5)

    Try doing both a SMC and PRAM reset, I'd do each at least 2x. Please click Intel iMac SMC and PRAM resets for instructions.

    I tried. But maybe I midunderstood part 2. I cam to restart the mac-os wich i did. But it ididn´t help. Then I pressed Command+option+r+p and it rebbot. But the decktiop and sreecnsaver still refuse to stop "reading picturece". And now my computer refuse to use wifi - and yes, i have connection. (It wish to upgrade i-tunes).

    First follow the instructions in this support article.

    If an iPhoto or Aperture library is the source of your desktop pictures, it may need to be rebuilt, or you may need to update the application to the latest version.

    Otherwise, continue as below.

    Back up all data.

       

    In the Finder, hold down the option key and select

      

    Go Library

      

    from the menu bar. From the Library folder, delete the following item, if it exists: 

     

    • Caches/com.apple.systempreferences

     

    and move the following item to the Desktop:

     

    • Preferences/com.apple.desktop.plist

     

    Launch System Preferences and test. If you still have the issue, put the item on the Desktop back where it came from and post again. Otherwise, delete the item.

    I'm not sure I understand your question. The screenshot shows the item I suggested you delete: com.apple.systempreferences.
