Q: Problem iMac 27inch late 2012 turn off randomly
Hi, my iMac shuts down randomly for no reason. I try to turn it on and don't works. Now unplug the socket for a few minutes and the iMac magically turns on again. I encountered this problem for some time and also some stains on the screen. I have reported this issue to Apple and they replaced the screen even if out of warranty and they did all the hardware-test possible and left on for several days and found no shutdown.They have specified that maybe it's a software problem. The iMac is connected to an APC UPS and thought that was the problem, but even excluding the ups the problem recurs. I enclose the etrecheck-report as a discussion from ditocura https://discussions.apple.com/thread/6832695?start=0&tstart=0 .
If anyone has an idea what might be and how to fix this problem would be grateful!
