Since I don't see the info currently available in Jamf Pro as built-in Smart Group or Advanced Computer Search criteria I created the following EAs to report the macOS version and deadline date of any pending Declarative Device Management Scheduled Update command. I expect/hope Jamf will add them as eventually, but in the meantime...
EA script that returns a String Data Type with the version number for any pending DDM scheduled macOS update:
#!/bin/sh
DDMSoftwareUpdateInfo="/private/var/db/softwareupdate/SoftwareUpdateDDMStatePersistence.plist"
result="No Update Pending"
if [ -e "$DDMSoftwareUpdateInfo" ]; then
pendingUpdate=$(/usr/bin/defaults read "$DDMSoftwareUpdateInfo" | /usr/bin/grep TargetOSVersion | /usr/bin/cut -d \\" -f 2)
if [ -n "$pendingUpdate" ]; then
result="$pendingUpdate"
fi
fi
echo "<result>$result</result>"
EA script that returns a Date Data Type with the deadline of any pending DDM scheduled macOS update (since returning a non-date formatted result from an EA set for the Date Data Type is a Bad Idea
this EA returns "2001-01-01 00:00:00" if there is no update scheduled):
#!/bin/sh
DDMSoftwareUpdateInfo="/private/var/db/softwareupdate/SoftwareUpdateDDMStatePersistence.plist"
result="2001-01-01 00:00:00"
if f -e "$DDMSoftwareUpdateInfo" ]; then
updateDeadline=$(/usr/bin/defaults read "$DDMSoftwareUpdateInfo" | /usr/bin/grep TargetLocalDateTime | /usr/bin/cut -d \\" -f 2 | /usr/bin/tr 'T' ' ')
if f -n "$updateDeadline" ]; then
result="$updateDeadline"
fi
fi
echo "<result>$result</result>"
