Intermittently, I witness a freeze with my MacPro and I was wondering if anyone has had a similar freeze and found a cure. Some background: I have my screen saver turned off. I have Energy Star set to never put the computer or the display to sleep. I generally Switch out to the Login Dialog and turn my monitor off because often times I remote into this computer and it freaks family members out when they see a computer operating by themselves...
On to the issue. Occasionally, when I turn my monitor back on, I see a dark screen with the remnants of the Flurry screen saver drawn to the screen. Note, it's frozen and nothing is responding. Often times, I can use the Eject button on my keyboard to "shock" the system into responding and it brings up the Login Dialog and I can continue as normal. However, sometimes, even this trick doesn't work. Then, what I have to do is use my laptop to ssh into my MacPro and sudo kill -9 the process for
root 12856 0.0 0.0 2476680 2420 ?? S 5:18PM 0:00.08 /System/Library/CoreServices/SecurityAgent.app/Contents/Resources/authorizationhost
Which then clears the dead Flurry screen saver image and brings up the Login Dialog and again, everything works as normal.
So, does anyone else have this situation? Do they have a better way to fix it so that this problem doesn't happen?
Note: I am using Mac OS X 10.6.8. Alternatively, if someone had this problem and upgraded to 10.7, was the problem fixed?
