I've having problems with my 24" iMac not going to sleep on its own. It will sleep if I manually tell it to do so, but it will wake up at random times. I have searched a lot on this issue and I think it is an issue with Mac OS X. There seems to be no rhyme or reason to the problem - it is happening on all different makes and models of Macs. I have tried adjusting the energy saver settings. I have tried shutting down all programs. I have tried shutting down all downloaded widgets. I have tried shutting the mac down, unplugging it for a while. I have tried unplugging peripherals. What else can I try? Sorry for the dumb question, but someone mentioned turning off the screen saver because it might interfere, but I can't figure out how to turn it off. How do I do that? Has there been any official statements from Apple about this?
