Has anyone tried this? http://www.andrewescobar.com/archive/2005/11/11/how-to-safe-sleep-your-mac/ Powerbooks have the ability to hibernate, this is basically a sleep mode where the contents of RAM are also dumped to disc in case the battery runs out. OSX has the ability to hibernate but it is disabled on iMacs and Power Macs. This hack enables it for these desktop machines. I'm curious if it will also be a viable solution for those of us with the Intel iMacs who are having issues with not being able to wake our iMacs from sleep.
