"How come my iMac keeps shutting down after these tries to fix?"에 답변Go back to pc. I have been a mac fanboy for 7 years and since the death of Steve Jobs apple has been living off its former reputation and Iphone. No new next big thing , quality has gone down hill , no touch screen, even customer service is not what it use to be. I am going to give microsoft another try . I tried a friends 27 inch HP envy and was very impressed.
