2012 iMac won't wake up

[pwcriswell]

Looking for a bit of help, and I have no doubt this has been asked before, just can't seem to find the right answer: I have a 2012 iMac that recently would go to sleep when asked, but after a certain period of time, just wouldn't wake from the space bar or mouse as it used to, and essentially required power off/power on. It does appear to be entering a hibernate mode from the console logs. All other behaviors seem to be normal.

Any thoughts would be appreciated.

What OS are you running?

Have you tried an SMC and PRAM reset?

I am having this same issue only with my Macbook pro 2013 model. I think this is a Maverick's issues

Make sure "Wake For Network Access" is ticked in Energy Saving. This will reconnect the iMac to Wi-Fi so it does not enter a deep sleep (Safe Sleep) after 4 hours of undisturbed sleep.
