We have to different packages that were created by Apple Professional services, knowing that we use Casper. We tested all packages with ARD at time of creation and just added them to Casper. These are being deployed to 10.8.4 computers that are at the login window and I know at least one of them runs a script as it is a universal bind script they wrote for use that displays what it is doing in big text across the screen.
Anyone else have a problem with .pkg in Mountain lion via Casper.
