Ok, this is very silly but I do not know how... I need my Mac Mini to wake up at 8pm, start up a quicktime video full screen in a loop until 2am, then shut down again. And I need it to do that over and over again for a month. How can I do that? I want to tell the computer what video to play back once. Probably I may create a new video later on and I would have to switch videos and play the new one only in a loop as well. The thing is... I have this projector that is gonna be playing back a video during nightime. No one is going to controll it. In order to power down the projector I need to put the computer to sleep and not sending any video signal at all. That way the projector will go to sleep and it will wake up again by itself when receiving a video signal. Thank you very much for your help.
