Well this has been my best computer system I have ever owned. I have had zero problems with it until now... When my 24" iMac is off, the system will randomly power itself on. There is no specific time when this occurs but if I power it off at night, it will be powered on in the morning. The first time it happened I thought I didn't actual power it down but I have been following this issue for 2 weeks now and have decided to raise the question here. Under "Energy Saver" I have unchecked "wake for ethernet network administrator access" out of suspicion that someone is powering my system from the internet. Are there any thoughts to what might be doing this?
