Hi all,

Hope somebody can help me. For the past week or so my iMac just randomly shuts down. There's no pattern or warning, just boom black. It starts up normally again, sometimes for 5 minutes, sometimes for 5 hours before shutting down again.

I have a temp app installed and right now it's at 42C for the HD. I've also repaired permissions. I had a disk issue and had to boot from the CD, but that also repaired without issues.

My log for the latest shutdown:

Any clues?
 
Thanks I did the SMC reset and so far so good. I just looked at the log though and Chrome is still throwing the same error, though without a shut down.
How would I go about reinstalling it? I assume just dragging the app to the trash is not going to completely deinstall?

Thanks so much!

The only effective method for complete app removal is manual deletion:
 
Da**. Happened again this morning. Oddly enough when I walked away from the computer to refill my coffee. Same error though, so I guess I won't be using Chrome anymore. Firefox here I come, again.

Seriously, there's something not right there. Many use Chrome with no problems at all, so something is amiss here. Some complain about Chrome, while others swear by it. The same is true for Firefox and Safari (my personal preference). None of them should be crashing frequently.
 
Apparently the wrong kind of coffee! ;)

Do you have any other suggestions of what I can do? I was just looking at the disk permissions and repair disk and there's new errors again, even though I just repaired both a day ago. So something is definitely not right.
 
My 2010 iMac i7 has a similar problem... but it seems to shut down only sometimes when i put it to sleep - eg: put it to sleep at night, when i wake up in the morning, it's actually shut down, so have to power it back up... but it's not consistent...

When I spoke with Apple Support a few weeks ago, they did the usual PRAM and SMC resets and also deleted some powermanagement plist file.

Finally, I had to verify & repair disk permissions, but from disk utility on the install DVD...

it was fine for a week, and today it's happened once.

going to monitor it for the next few days before calling apple support again.

i suggest you call them to see if they can assist.

Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore
About Disk Utility's Repair Disk Permissions feature
Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. For example, if you install an application using a non-Apple installer application, or by copying it from a disk image, network volume, or other disk instead of installing it via Installer, a receipt file isn't created. This is expected.

Well crap! Came home from work and my Mac won't turn back on. That's the last thing I need right now, but I guess I need to ship it off.
 
For anyone curious, the problem was the powersource which was replaced by apple. Had my computer back for 2 days now and no issues.
