Mountain Lion takes long time to shutdown The fix does not stay, guess I'll wait for Apple to releases a fix.



It usually shutdown in 2,3 seconds while I was on Lion. I upgraded to ML recently and this happened.

In launchd-shutdown log, I found this

20006079 com.apple.launchd                1        com.apple.securityd      17        Exit timeout elapsed (20 seconds). Killing
20008561 com.apple.launchd                1        com.apple.coreservices.appleevents 65        Exit timeout elapsed (20 seconds). Killing


Things I have tried but no luck:


I have reset PRAM
clear kext-cache. it works at first shutdown only though.


Any idea how to fix this!?
Take a look at the following threads:

In short, it was recommended to: "removing items from Login Items for the user account and adding them back one at a time while testing restart/shutdown. Also, clearing out the ~/Library/Saved Application State folder and the System/Library/Caches folder and making sure your ML volume is selected as the volume to boot from in System Preferences / Startup Disk."

Also, maybe you have Dropbox/Google Drive/Software Update that runs in the background? 

Another thing that mentioned was to uncheck "Reopen windows when logging" when shutting down for quick shutdown times.

Can you tell us which applications you think might cause problems?
