    I have a mid 2011 iMac i5 27'' on which I have installed Mountain Lion.

    Everything is working great, except for one thing.

    I have my Energy Saver set to the default Sleep of 10 mins of non use. Whenever I was downloading anything under Lion it would always stay awake until the download had finished, even if that was 2 or 3 hours. Since changing to Mountain Lion my iMac sleeps exactly as per Energy Saver settings regardless of the fact that there is network/hard drive activity.

    Is there a setting somewhere which needs tweaking? I have tried checking/unchecking "Wake for Network Access", but that doesn't make any difference.

    Any ideas?

    What browser are you using to download things?

    Just realised that I have this problem as well.
    ML sleeps when I have downloading job.

    This does not happen in Lion.

    If it helps my week old MBA 11 goes to go into full sleep after 5 minutes (the setting for display sleep).

    Wake for Wi-fi does not work as before (development webserver).
