Hey... My iMac has been waking up allot during the night for the past few months... Someone when I come to it I find it not sleeping at all. I was told a few weeks ago when I catch it go to the system log.. I did that today and am now really worried its some sort of Mac Virus or something.. I could be wrong its just the name freaks me out. 26/06/10 2:07:44 AM com.apple.launchd.peruser.501 (com.apple.AddressBook.abd) The following job tried to hijack the service "com.apple.AddressBook.abd" from this job: [0x0-0xd9fd9f].com.apple.AddressBook.abd Edit: Looks like its every HOUR!
