Hackintosh Power Management

Also, be aware that hibernation (suspend to disk or S4 sleep) is not supported on hackintosh.

You should disable it:

sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage

Always check your hibernatemode after updates and disable it. System updates tend to re-enable it, although the trick above (making sleepimage a directory) tends to help.
