Q: Black screen and mac start-up tune repeated.
Hello,
I have a iMac 27' with 8gb ram i7 cpu and 2010 model with the newer os software.
In two weeks ago when i press start button i listen the classical mac start-up tune be repeated and the sceen is always black. Nothing more.It is repeated and repeated when i close manually my iMac.
You can't press cmd+R or something other.
I try disconnect from socket, disconnect all usb and fireware devices but nothing. The problem is the same.
Does anyone know something to help me ?
Thanks
iMac (27-inch Mid 2010), iOS 5.0.1
