Re: cron/Launchd Editor

I think you haven't followed the documentation or grokked the nature of launchd agents because the example above is still horribly wrong. Firstly, launchd is looking for an _executable_ not a script, so you have to use an executable like osascript to run the script. Secondly, the "Program" and "ProgramArguments" are an XML representation of <x-man-page://3/execvp> and mostly likely written so that they can be loaded into a format suitable for an NSTask-like invocation with a minimum amount of effort. Everyone has to follow that format for this kind of agent. And thirdly, in this case, you only need the StartCalendarInterval for the key/value pair. 

The following (save it as "ca.aker.playsound.plist" and remember to 'chown root:wheel'), is something that works OMM. At first, only change "some.scpt" into "playMantelSound.scpt" to check if it works on your setup (I'm on 10.6.1 BTW).

Since I don't have playMantelSound.scpt, I can only assume that it actually works in Script Editor. The "some.scpt" I used looks like:

say "bob"
