Why did my Mac shut down & wont power up again?...
iMac Model A1224. EMC 2133
My iMac turned itself off & wont turn on again. When attempting to turn it on it felt as if there was no power going to it. I checked the power cord & power strip, not the problem. How do I find out if it's the power supply, adapter or the Motherboard?
Is this a good question?
