As the title states, I have been using Mavericks for well over a month now with no problems (Imac 2011 27"). However, I turn on my computer today and all of my icons on my desktop have disappeared. I can create new files and have them show up, however I cannot find a way to have the old ones visible. I have updated Mavericks, I have restarted the computer, re-logged in several times. No luck. My desktop appears to be normal through finder, yet nothing is showing up on my actual desktop. Any help?
