I have a 2011 iMac. Two days ago it would not turn on...have checked the power outlet and it is working.
I suspect the problem is not in the cable to the power bar. This machine was a lot of money and was working
well 3 days ago. Do you think it is the power supply or could it be worse and be the motherboard?
My question is related to a major concern...I do not want to be raked over the coals by some apple service centre
to run their diagnostics and levy a very large cost in $. What are the chances that it is the power supply? If it
is just the power supply I am prepared to pay the $ for the power supply but if they try to take me around the bend I will dispose of this computer. What is your advice?
