I've got a brand new Mac Mini running 10.7.3 and i want the Screen Saver to kick on and rotate through pictures... The problem is my Screen Saver Dialogue box has almost NOTHING listed in it. See attached screen grab... It only has the "Apple" triangle with the "Computer Name" or "Flurry" Screen Savers listed. I can't find anyway to reset my Screen Savers, so i tried installing a few new ones, which flashes the screen when they are installed, but they don't show up. When i try to install them again they say there are "already installed" and would you like to replace... But nothing is there. Even when i try to just add a folder of pictures with the "+" sign, i can select the folder, but it just flashes the screen and it does NOT show up. Does Anyone know what might have happened?
