I have MacBook Air 2013, Mavericks installed.

I recognized that my mac is a little bit warm. Thus I looked into Console

These logs are repeated again and again with time interval about a couple of minutes.

I searched some articles and found that I can see why Mac wakes up by looking into Wake reason. But in my case, the reason is Question mark (?)

What should I do right now?

Is there any way to see which factor wakes mac up?

  • I have this identical issue, I had my laptop lid closed overnight, came down and it was warm with the same errors. It seems to be continually rewriting the hibernate file, too, which scares me a little as it's going to have been thrashing my SSD. Hardware is 2013 MBPR. – Alex Berry Nov 18 '13 at 12:48

I had this issue with my MacBook Air Haswell and OS X 10.9. You can add a workaround for this by disabling standby/hibernation.

Open the terminal and type:

sudo pmset -a standby 0

This will disable hibernation. To activate it again type:

sudo pmset -a standby 1

If you look at the log closely, the "sleep loop" starts right after going into deep sleep (hibernation) after 3 hours in energy saving mode. You will lose 2-3% battery over night but still better than a sleep loop.

If you have Avast! Antivirus installed, I would try uninstalling it first, this fixed the issue on my Mac.
