Late 2010 Mac mini 2.4GHz 8GB 1333 MHz DDR3 320GB OS 10.6.8 in great shape. Only problem is the monitor or the mini. Waking from sleep my screen opens with a desktop bigger than the monitor setting causing the menu bar to disappear. What I then have is a background picture without the ability to control anything. Sometimes I have to turn off the computer and re-start and usually it provides the correct desktop. Sometimes I can reset the desktop by turning off the monitor and turning back on. I like this mini and I thought it was getting ready for the trash bin, so, I bought another mini just like it. Guess what? The one I bought does the same thing. Now I have 2 with the same problem. In the display prefs there is a setting named “arrangement” and although I tried to use it I had no luck. This is getting annoying and I hope somebody has a solution or even a place to find a way to stop it? Thanks.
