How to "Action" when a Mac Reboots

If your Mac reboots, and you want to be notified that it has rebooted.

How to launch a Script when your mac reboots

Create a .plist file at /Library/LaunchDaemons/com.YOUR_COMPANY.rebootnotification.plist. Change YOUR_COMPANY to your domain name in the .plist file. The contents will look like the following, change /path/to/your/script.sh to your script. This .plist file and the /path/to/your/script.sh should be owned by root:wheel my advise is to make it only executable by root. I take no responsiblities for any Security issues.
