Hi, My 11" MBA has gotten some sort of "attack". It shows a black screen with the multi-colored little ball circling around. I usually turn the MBA off at night. However, last night I only closed it. The hard drive is very full at the moment and I wanted to remove the iPhoto Library file to relieve the hard drive, but I have woken up to the surprise that the MBA has that kind of "attack". I just want to be able to turn it off and on again. Thank you in advance! Kind regards, igmolinav : ) !!!
