Smart Group for missing Filevault2 Keys

Hi Jamf Community,

i have been trying to setup a search for all devices that dont have a personal recovery key set . Unfortunately there is no such option. Then i thought i could just check if the Filevault Encryption is "Valid". This would be great but, some of the devices in my jamf network dont have a recovery key set, but are encrytped. I was trying to figure out how to search for all of these devices so i could issue a new key for them. Is there any way to do this ?

Thanks ahead,

Raffael

Don´t know if it works anymore, but you have to setup an extension attribute:

Check the status of the encryption:

# following message is displayed without quotes:
#

if [[ ${osvers_major} -ne 10 ]]; then
  echo "<result>Unknown Version Of Mac OS X</result>"
fi

# Checks to see if the OS on the Mac is 10.7 or higher.
# If it is not, the following message is displayed without quotes:

Then create a smart group like this:

just modify the settings in the smart group like you want.

Hey mickl089,

thanks for your quick reply. I have seen this post myself, but 1. i cant confirm if its outdated and 2. This dosent check if a key present. As i already said some of my users have an invalid or unknown Filevault 2 Setup but still have a key, or even the other way round. They have no Key but the Disk is Encrypted. I guess it will boil down to manually searching for them.

Thanks,

Raffael

@Raffael , I've attached an image of the smart group I use to find keys in my Org which are not valid. I can verify it works. If you set it up like this, mind the parentheses. I exclude Mac minis in our environment because they're desktops. So, if you have iMacs or other desktops, you may want to exclude those. Up to you. Hope it helps.
