After upgrade to 10.6.5, I get forcibly logged out
Twice, so far. Every application I'm in is immediately terminated - no save! - and I am presented with the Login window.
The first time, I went into Time Machine. I clicked at a spot on the screen and bam! Time to log in.
The second time I was in Itunes. I selected the Visualizer, selected full screen mode, and then typed command-F - hoping (since I'd never tried the visualizer) it would take me out of full screen. The image froze. I clicked my mouse and bam! the music stopped, my screen went blue (as if the system was rebooting) and then showed the default background and the Login window.
This is pretty scary. Is there a way to downgrade to 10.6.4 safely?
And another log...
I didn't do the PRAM reset. I let it run another night.
And, sure enough, the thing did once again log me out in the middle of the night.
Again:
1/1/11 2:37:47 AM com.apple.launchd[1] (com.apple.loginwindow[3614]) Job appears to have crashed: Segmentation fault
And again, for the third time in a row, the loginwindow crash was preceded by:
1/1/11 2:37:47 AM mDNSResponder[18] Bad service type in .
ceqkJTTBHE69H6UQ-3J3X.tcp.local. Application protocol name must be underscore plus 1-15 characters. See <http://www.dns-sd.org/ServiceTypes.html>
Very odd.
Even worse, now that I have been logged out, the loginwindow process crashes every hour or so. Presumably this process is just sitting there waiting for a user login.
So there seems to be some badness in there somewhere.
So I reset the PRAM as was suggested earlier.
I rebooted.
I logged in. I did a minimal amount of work on the first day of the new year.
Later I got the same bad result. Instant and total logout. The system stays up but all my context is gone in a blink.
1/2/11 1:04:04 PM com.apple.launchd[1] (com.apple.loginwindow[86]) Job appears to have crashed: Bus error
And, as has happened 4 out of 4 times this preceded the bad news:
1/2/11 1:04:04 PM mDNSResponder[18] Bad service type in .
ceqkJTTBHE69H6UQ-3J3X.tcp.local. Application protocol name must be underscore plus 1-15 characters. See <http://www.dns-sd.org/ServiceTypes.html>
That's maybe something that happens after the fact.
A number of terminal windows logged out just before this log entry such that this log entry might come from the something else - at the same time as the loginwindow failure.
Anyhow, now it's getting to be time to start from scratch. The dreaded full system reinstall.
I've written in this topic before but I need to write again. This happened to me just a minute ago and that was for the third time after I had reset the PRAM. It doesn't do anything for the good. For me it seems like the rate of log outs raised but I'm not sure. This time, my screen flickered for a very long time until I forcefully had to shut it off by holding down the power button for some time. The crash seemed to happen when I switch tabs in Safari from the Telegraph's site to YouTube.
There was no crash log created by the system but this is a crash report from when this last happened.
So far nothing has happened to me. I did a combo update instead of the update provided by the software updater. How's it going for others who have updated through the software updater?
This happened again a couple of minutes ago. It's getting REALLY annoying so please Apple fix this!
I noticed that the crash happened when the "free memory" (RAM) was very low (about 40 MB and I've got 4 GB of RAM). The inactive part was very high also but I've been told in the past that inactive RAM is as accessible as free RAM, but I don't know if this is right. Maybe there's a connection?

This happens to me twice a day now. Every time I fullscren a flash video or VLC Player, the mac gives me a light blue screen of death and kicks me to the login screen. Upon login, CPU utilization goes to 100%, fans start blazing until I reboot. Have the same Macbook Pro 2.2Ghz late 2007 model as everyone else. Upgraded to 10.6.6 with no improvement. PRAM has been reset a few times with no improvement either. Took it to a Genius bar and the the genius ran the generic system tests which all came up green. He blamed it on having too many icons in my menu bar(~8). Anyone else under AppleCare and manage to get a fix/replacement?
*SOLUTION AS QUOTED BY USER uplink13 START* {
It seems i've somehow solved this problem reinstalling drivers and extensions from SL Graphics update.
Although this is not a clean and elegant solution, it seems to be a workaround till Apple solves the drivers.
You'll need Mac OS X SL Graphics Update 1.0 (download it from Apple), and Pacifist software (shareware copy is enough to perform this once).
0. BACKUP!!!!!!!!!!!!!!!!!!!
1. Install Pacifist
2. Download SL Graphics Update 1.0 from Apple downloads
3. Mount DMG, but don't run the update by double clicking it.
4. Right-click on the "SnowLeopardGraphicsUpdate1.0.pkg", choose "Open With..." and choose "Pacifist" from the list.
5. In Pacifist navigate to "Contents of SnowLeopardGraphicsUpdate1.0.pkg", right-click it and choose "Install to Default Location".
6. Enter your password and wait until pacifist extracts all of the content to your system drive (agree to replace existing files).
7. Open /System/Library/Caches and delete everything from that folder (authenticate with your password).
8. Open /Library/Caches and delete everything from that folder (authenticate with your password).
9. Open "Terminal" app and type "sudo touch /System/Library/Caches" (authenticate with your password); "sudo touch /Library/Caches" (authenticate with your password again).
10. Restart the machine (it would be longer to start after rebuilding extensions caches).
ps.
i've reinstalled only the portion of extensions regarding to NVidia drivers because my MBP is NVidia powered, and of course Frameworks and /usr. ignored Intel and ATI graphics.
*SOLUTION END*;}
Thank you, uplink13 <3
My MacBook Pro3,1 2,2 GHz 4GB RAM has been running without ANY hiccups since this solution and I've pushed it very hard with apps and full-screen Flash video and hi-res MP4 video.
And yes, on 10.6.6 btw.!
SO PLEASE, follow this Russian genius' (uplink13) instructions.
