Hi all! My iMac doesn’t turn on normally. The thing is that it works properly when its up and running. The only way to turn it on is reseting the SMC: Unplug all USB devices and the computer.Wait for 15 seconds.Plug the Mac back in and wait another 5 secs.Turn on your Mac. I have replaced the power supply and the CR2032 PRAM battery… and still having the same problem. ¿Is that a logic board issue? Any help appreciated. Thank you!
I would check your outlet making sure its properly wired 3-Wire Receptacle Tester Are you using a surge suppressor or better yet a UPS?
