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.

Check this thread as well - I have been facing some wake-from-sleep issues, but after a SMC reset things seem better...at least for now.
