    Never had this issue in 10.8.1, but have been noticing my iMac waking from sleep in the middle of the night. It is quite frustrating as I have my iMac in my bedroom and the brightness of the screen seems to wake me. Anyone know of any fix for this? Thanks ahead.

    A few things to try:
    Repair disk permissions
    In Sys Prefs>Energy Saver, make sure the "wake for network access" is unchecked
    In Sys Prefs>Bluetooth>Advanced, make sure you have "Allow Bluetooth devices to wake this computer" unchecked.
    Reset the SMC (http://support.apple.com/kb/HT3964)

    Hopefully it's something as simple as that, if not then either there's a new bug in 10.8.2 or there's a poltergeist trying to check their email in the middle of the night on your iMac.

    Will definitely give these a try. Thank you!

    Also, I seriously hope there is not some poltergeist trying to check their email in the middle of the night! Ha.
