Steve: You don't need to chmod the file NSTask is really meant for executing Mach-I executables, so the launch path needs to be the interpreter. For example, if this is a ruby script your launch path would be /usr/ bin/ruby and your first argument would be the first argument. If it's a shell script you would use /bin/sh and the script would be the first argument (and so on and so fourth).
