So I sometimes download large files and leave it downloading when I go to bed at night. I set my iMac to shut down at say 4 or 5 in the morning when the downloads should be done. I only set it to automatically shut down through the energy saver settings. HOWEVER, whenever I do this...no matter what time I set it to shut down, my computer always starts itself at 4pm. Can anyone tell me how to stop this from happening?
