Hello, I am new to this forum and I am new to the Apple world, bought an iMac 2,4 a month ago and I am more than happy with it. Most of the little issues that came up in the first weeks of operation I have resolved, often reading useful threads in these forums. My problem now is that my iMac turns on alone, from time to time, although I have not scheduled it to do so in the "energy saver". I normally turn it off at the end of the day, I mean off not sleep mode, but sometimes I wake up in the morning to find it already waiting for me in the user log-in screen. As far as I am aware, there is no software that I have installed and requires it to switch on (I understand the time machine does not do that). Any ideas? Thanx a lot, T.O.
