I had this problem with 10.6.8 but not with 10.7.5. Lion was the best running OS I've had on this customac so far. Never ran 10.8 but now that I'm running 10.9 the computer goes to sleep but can only be woken up by pressing a key, then unplugging and replugging a usb device and then pressing a key again. How can I fix this? My system specs are as indicated in my signature.
