Ive set it to go to sleep (screen & computer) after 10 minutes in the System Preferences. Usually if Id download a file, the screen would go to sleep after 10 minutes and the computer would go to sleep whenever the download is finished. However, with the App Store, this doesnt seem to work. The computer goes to sleep after 10 minutes and interrupts the download. Anyone know a solution apart from setting it to Never, which I do not want?
