Ok since I installed Yosemite its been problem free up until now. I let the machine go to sleep probably no more than 10 to 15 minutes and when I woke it up I could not log back in!
My little log in logo was there but the box for the password was not. I could not remember the command to force quit. I tried to turn it on and off but it did not work. Screen would just go black and when I turned it back on same problem. I finally had to unplug the machine and restart it.
Anyone got any idea what might have caused this?
