10.9.4 update freezes and does not wake properly up from sleep
After I installed this update (v10.9.4 Update) I have problems when "waking up from sleep" (something this was supposed to fix, but never was my problem). It now freezes a lot and when I force a reboot (holding the power button down) sometimes a question mark blinks or a circle with line across. Normally I force reboot again and then it works. Has anyone experienced same issues and found a solution to it?
