I’ve had my Macbook Pro for a couple of months now, and I recently ran into a problem when downloading a file with the lid close. I’m not sure why the Mac has this feature and doesn’t include a setting in the preference….Anyway, what you can do is download an application for the Mac called “InsomniaT”. Once installed, you can access this from the Preference/Settings menu. You can choose to suspend or not suspend the Mac when the lid is closed. This way, you can go on downloading files over the night with you Mac lid closed. Below is the link, to where you can download the application.
