Hi, I have a mac mini setup running in headless mode (no screen attached). I need to power off the mac when the power button is pressed, and there should be no confirmation dialog appearing.... as soon as button is pressed, begin shutdown procedure. It must not be a hibernate or sleep / suspend mode either, but needs to be a complete "halt" / power down. (It's a special project, don't want to go into the reasons why, but suffice it to say that those are requirements that cannot be changed) Is there any way to do this? It is so easy on windows and linux I have to assume I'm missing the obvious somewhere here, but for the life of me I can't figure it out on osx... Thanks!
