Woke up thinking I had slept longer than I thought with the sun already rising, until I realized it wasn't sunlight but the light from my awakened imac. I had put it to sleep hours before when I turned in.

This one was purchased new last December.

Is there any way of viewing what was going on in my computer that would have awakened it from sleep mode?

Any way of seeing a history of attempts to use my wifi network?

thanks,
zep
 
Applications / Utilities / Console will help you, and Macs don't wake from being access via wireless LAN, but maybe a connected bluetooth device was triggered in some way.
 
So, wake for network access under energy saver in system preferences is turned off? Both your bluetooth keyboard and mouse have battery levels that aren't critically low?

Those would be the two top reasons for your mac waking up on its own accord.

No, the wake for network access was not turned off. Thanks for pointing this out to me. I am assuming that blocking this prevents me or anyone else from waking my computer remotely?

I may turn it back on later if I find out this is the case, since ultimately I'll be wanting to do that.

I have the wireless keyboard and mouse that came with the computer, and the keyboard batteries are running low. This would somehow trigger my computer to waken?

PS: Should I be using the push button to turn the keyboard off after each use?
 
The bluetooth keyboard and mouse dynamically power down every chance they get, so it's not really needed to turn their power off when putting the computer to sleep. If their batteries are low, they won't wake the computer. It's only when their batteries are critically low (like under 10%) that they wake the computer.

It is most likely your wake for network access.
 
Airport isn't powered off when asleep. My iMac has awakened on me several times during the night via my wireless network.
 
My iMac was purchased in July and required a new logicboard in August. It had problems with the sleep function. It has been perfect since the repair.

Thanks for addressing my questions so well. This was exactly the information I was looking for and very helpful.

Unfortunately, the information I pulled up with it also leads me to more questions, which I am in the process of doing a little googling on right now.

So I may have a follow up question(s). :)
