I use Transmission as my app - I keep my rMBP by my bed. I'd prefer to be able to just start a torrent, close her up, then check back in an hour to see if it's completed? I know it can (and does) check for and download system updates - is there a link to what else she can do while she's "asleep"? I'd even like to be across the house with my iPad and check in - just not sure what's allowed and what's safe? I definitely don't want her to overheat. Thanks for any info or links - for my iPad, I use Splashtop Streamer - have never even tried it with the lid closed, though.
