Potential Bug: At Reboot and iCloud Setup

I found to add Sleep 30 to my script as a work around.

Matt, you don't need to add a sleep to your script. If you let the iCloud setup screen go the jamfhelper.app should take care of this eventually and you'll see the usual finishing installing software screen.

and does anyone know how to disable the iCloud setup wizard? usually, we'll turn off the OSX start-up wizard by clicking that button in casper admin or by entering something like:

touch var/db/.AppleSetupDone

into a script. but is there another file for the iCloud set up wizard?

Have a look here-
