I had a problem over the weekend where my iMac would wake up seconds after putting it to sleep, and also rebooting after shutting it down. The full story can be seen on this thread here: http://discussions.apple.com/thread.jspa?messageID=10579459� At first I thought it was caused by an installation of iMagneto, but it eventually becomes clear that it was caused by what I presume was a corrupted folder (Application Support). I've not been able to find out any more info about this bug outside of the Apple support forums so I was wondering if anyone else has had this problem. The original thread in the Apple forums dates back to early September so it looks like the 10.6.1 and 10.6.2 updates didn't address it. Is it a very rare bug I wonder?
