Set Terminal disc access in Jamf

Hi,

Jamf is supporting default scripts for checking time machine backups. But with new versions of mac os this won´t work beuacse diskutil is using PlistBuddy. This has no disc access. If i enable Terminal in full disk access those scripts are working again.

Without disc access

With disc access

How can i set Terminal do full disc access via configuration profile?

you don't want to grant terminal full disk access.. thats 'a bad idea'

not sure why plistbuddy is requiring access, but this does not.. you'll need to work that a bit to get the result you need, but you get the idea.

defaults read /Library/Preferences/com.apple.TimeMachine.plist | grep LastDestinationID

This is the script that Jamf offers in Custom attributes. This does not work anymore with newer MacOS Version.

#!/bin/sh

enabled=`/usr/bin/defaults read /Library/Preferences/com.apple.TimeMachine AutoBackup`

if [ "$enabled" == "1" ]; then

    # Determine the OS version since the destination key name differs on OS

    OS=`/usr/bin/sw_vers -productVersion | /usr/bin/colrm 5`

    
    if [[ "$OS" < "10.7" ]]; then

        backupDestination=`/usr/sbin/diskutil info $(/usr/bin/defaults read /Library/Preferences/com.apple.TimeMachine "DestinationVolumeUUID") | grep "Mount Point" | /usr/bin/cut -c 30-`

        validateDestination=`/usr/sbin/diskutil info $(/usr/bin/defaults read /Library/Preferences/com.apple.TimeMachine "DestinationVolumeUUID") | awk '{print $1, $2}'`

    elif [ "$OS" == "10.7" ]; then

        backupDestination=`/usr/sbin/diskutil info $(/usr/libexec/PlistBuddy -c "Print DestinationVolumeUUIDs:0" /Library/Preferences/com.apple.TimeMachine.plist) | grep "Mount Point" | /usr/bin/cut -c 30-`

        validateDestination=`/usr/sbin/diskutil info $(/usr/libexec/PlistBuddy -c "Print DestinationVolumeUUIDs:0" /Library/Preferences/com.apple.TimeMachine.plist) | awk '{print $1, $2}'`

    elif [[ "$OS" > "10.7" ]]; then

        backupDestination=`/usr/sbin/diskutil info $(/usr/libexec/PlistBuddy -c "Print Destinations:0:DestinationUUIDs:0" /Library/Preferences/com.apple.TimeMachine.plist) | grep "Mount Point" | /usr/bin/cut -c 30-`

        validateDestination=`/usr/sbin/diskutil info $(/usr/libexec/PlistBuddy -c "Print Destinations:0:DestinationUUIDs:0" /Library/Preferences/com.apple.TimeMachine.plist) | awk '{print $1, $2}'`

    fi



    if [ "$validateDestination" == "Could not" ];then

        echo "<result>Destination not mounted</result>"

    else

        echo "<result>$backupDestination</result>"

    fi

else

    echo "<result>Not enabled.</result>"

fi

I will try your snipped. Thanks

OK, i changed the scripts and i want to share them if somebody else wants to check time machine status
