Question: My iMac does not fully start up and I have tried every keyboard start up code I can think of. When I press the power button it chimes that it has power and I see a white screen that turns black.
I have tried every keyboard start up code with no start up. I hear the chimes and see a white screen that goes black. When I first started having problems it went to the log in screen and it closed too fast to enter me password. I am at a loss and getting very concerned.
