My ISP offers unlimited downloads at a certain time period at night, but I don't want to wake up to shutdown my MBP 13.3 at that time. I tried to specify a certain shutdown time using the Energy Saver option.
However, I found out to my utter dismay that Transmisison needs to be explicitly closed before it for the computer to shut down.
