Black screen after hard drive replacement
I followed the guide on this iFixit for replacing the hard drive on my iMac model but when I reconnected everything and turned on the Mac, you could hear the classic dong boot but the screen remained black. I tried to connect with the adapter to an external monitor, but it is always black. If earlier worked perfectly without any problem, what could have happened? I tried all combinations of keys at startup, but nothing has changed .... helppppp !!!
Questa è una buona domanda?
