i restarted after a night's sleep and it gave me a frozen blue screen , i had to do a force hard restart
any ideas as to what could be causing this ?
i fear it may be a usb issue as i had a printer directly connected to my keyboard , rather than at the rear of the mac
odd considering intel invented usb
just hope it's not a sign of things to come with them , apple always made reliable good quality mobo's in my experience
