when when changing a background on my Mac Air, my screen freezes
I just got a new MB air on Friday (8/30) and did the migration from the old MB air but when I want to change the packground... but the system preferance screen freezes and the wheel just spins and spins...I have to force quit it. What is going on? I have had 3 Mac laptops and two desktops and have never see that happy before... it an i7 with 8 gigs... it shouldn't be doing that.
MacBook Pro, MacBook is only 1 years old
