Why does my Mac turn itself on (wakeup, startup) at night?

I am running a Mac Mini (Intel Core 2 Duo)on OS X 10.6.7.

It irregularly turns itself on, from shut down state, at about 4 in the morning. I have checked that there are no sheduled alarms in Calendar, or programes set to record on EyeTV, which are the only wakeups I might have set.

This is the Console log from this morning:

After that, it records nothing apart from Firewall chatter until I get out of bed and yell at it.

Do you have Wake On Demand enabled ? If so, Apple says:

With Wake on Demand enabled, your Mac will occasionally wake for a brief time, without lighting the screen, in order to maintain registrations with the Bonjour Sleep Proxy. On some Macs, sounds from the optical drive, hard drive, or fans may be heard during these brief periods.

For full article see: http://support.apple.com/kb/HT3774

In addition you can reset SMC http://support.apple.com/kb/HT3964- it helped me some time ago when my imac had similar problems.

Sounds like you have Wake On Lan enabled and maybe a printer share setup.

What are your settings

System Preferences/Energy Saver/Wake for Network Access ?

@JPM-PL Thank you. Its a good suggestion. I just checked the SMC article but it does not apply to this problem since I unplug the Mini ever few days and this has not stopped the problem.

@dechamp Thanks also for your suggestion. My setting is unchecked for System Preferences/Energy Saver/Wake for Network Access.

I thought the printer wake up was the problem but after unplugging my network printer and then reinstalling it as a USB printer (which I turn off at night), I still have the problem.

Are you using a UPS power backup system, or an Apple Airport Router?

I had the same problem except my 27" iMac turned on every morning. I do not have a UPS - it's plugged in only to a surge protector PS. I only noticed the iMac woke up only if I woke up extra early (around 5 am). So, I got on the forums this morning to see if there were any solutions. There are lots of complicated explanations for this phenomenon.

I finally went to my Systems Preferences > Energy Saver > Schedule and saw this - I unchecked the start up box - now I'll wait until tomorrow to see if it fixed the issue. I think I'll leave the "Wake for network access" alone (this was default) to see if the first step fixed the issue.
