iMac. Replacement of RAM resulted in a dead iMac.
I recently replaced RAM in my iMac (late 2013), and of course I forgot to disconnect the power cable. Something was shortened and computer died. Now it won't start at all.
What could it be and how to test components inside? I have another iMac but I don't want to tear apart the working mac and try different components one by one..
iMac 27″, macOS 10.15
