i rarely ever shut my Mac down, i usually put it to sleep. several weeks ago it started waking up on it's own, only to go back to sleep after my settings to power down, once it does it may wake up within a few minutes or as long as an hour later, so now i have to shut it down every morning and evening. what's wrong and how can i fix it help ! Hi Folks, i want to bring you all up to date, i probably upset a few folks , couldn't help it, i thought the problem was fixed as it went a week or two without a wake up, then it started all over, i worked on every angle i could come up with when i decided to change my Logitec Wireless Mouse with my Apple iMac Wireless Mighty Mouse......, i have gone for over two weeks now WITHOUT A WAKE UP !!
