The -S command will run the command /usr/local/sbin/sleepwatcher -d -t9000 -i "/usr/local/sbin/sleepwatcher -n" -p /tmp/sleepwatcherid every time the display sleeps. The first line calls an instance of sleepwatcher with three arguments: -V (for verbose logging), -S (to run a command on display sleep), -W (to run a command on display wake) Similarly "RunAtLoad" will perform the "ProgramArguments" at login.Īs for the actual program arguments, they are a bit more complex: /usr/local/sbin/sleepwatcher-V-S /usr/local/sbin/sleepwatcher -d -t9000 -i "/usr/local/sbin/sleepwatcher -n" -p /tmp/sleepwatcherid-W kill `cat /tmp/sleepwatcherid` First, the option "KeepAlive" will perform the "ProgramArguments" whenever the process sleepwatcher is not running. This could benefit from some explanation as to what the launchd file actually does. That being said, although I have not tested this script either, this seems like a valid method of forcing an idle-time based sleep if other methods fail. Especially in circumstances like this where a slight error could cause the computer to continually sleep or shut down. The reason is that if they cause issues they are difficult to debug for the average user. Generally, I don't think its a good idea to recommend launchd modifications/additions without understanding exactly what they're doing.

So I've detailed the steps below to make it work system wide (and no it won't go to sleep if you're watching a movie) and hope it'll help those of you who have an insomniac Mac for whatever reason. Unfortunately, all the hints mentioned here either did not work for me, were incomplete, needed some other utility to work, or had an outdated method for launching.
I did some research online and noticed that many people with real Macs were having similar issues (in my case it's because of the DVD drive), and then I found this site with a link to SleepWatcher a very good utility! I built a customized Mac and was very happy with it, until I realized that it wouldn't automatically go to sleep regardless of my Energy Saver settings in System Preferences.
