My imac (Intel) display is frozen. Both the mouse and the network are working. I've shut down various times, pulled the cord from the receptacle on the power strip, and restarted several times. No luck. Has anyone had problems like this and were you successful at fixing it? Thanks. Would appreciate any help. Paula
Same problem, but a c.2009 iMac running OS X 10.9.1. Just happened overnight. Presently, I'm able to access my HD via wireless via laptop and copying all non-backed up files to an external drive. So far, Paula is the only other person I've found with this same problem and hers was three years ago! Going to keep searching for an answer.
