iMac turns itself off
I've had this problem for about a month now: once started and on the login panel, the iMac turns itself off.
Here's what Console says:
*Jan 28 10:00:24 localhost com.apple.launchd[1]: * launchd[1] has started up. **
*Jan 28 10:00:34 localhost blued[17]: Apple Bluetooth daemon started*
*Jan 28 10:00:34 localhost mDNSResponder[18]: mDNSResponder mDNSResponder-258.14 (Nov 18 2010 14:18:32) starting*
(....)
*Jan 28 10:12:57 iMac-2 configd[14]: PMConnection IPConfiguration com.apple.powermanagement.applicationresponse.slowresponse 802 ms*
*Jan 28 10:12:57 iMac-2 configd[14]: PMConnection AirPort configd plug-in com.apple.powermanagement.applicationresponse.slowresponse 803 ms*
*Jan 28 10:13:01 iMac-2 configd[14]: PMConnection mDNSResponder com.apple.powermanagement.applicationresponse.slowresponse 4712 ms*
Then I came back at 11am and had to start manually. Once logged in with Mail open, iMac doesn't turns itself off.
What I did to try to solve the problem:
1. Although my system was up to date, I downloaded and installed the 10.6.6 combined update. Problem was still there.
2. I booted to my restore DVD, ran the system reinstall and ran Software Update until everything got up to date.
Unfortunately, all that did not solve it.
I've no idea what the Console information means.
Any suggestions?
Thanks.
