Hey guys, I just got my new iMac and I need to download software, films, files, whatever, and I'm in the process of doing that, and anything else in the future that I need to, I will download it. The issue I have is, I don't like downloading when I'm on my Mac, as it slows my bandwidth. I want to be able to turn off my screen, but let my iMac continue running programs in the background, ie. downloads. If I put my iMac to sleep, obviously it shuts off everything, and I can dim my screen, but not all the way like I can on my MacBook. Any tips would be appreciated.
