After upgrading our Macs on mojave 10.14.6 we had see that many Macs have the wrong recovery partition version (10.13, 10.12, etc…). We realized this when we wanted to reinstall a macos computers again. My question is the following, how can I find out the version of the recovery partition on macs with a script and how do I get it on all macs to the mojave version?
Question
Wrong recovery partition version
+8We created an Extension Attribute, to list the version of the Recovery HD.
CAVEAT!! We use this with Sierra and older ONLY. I have not tested it on High Sierra or higher. I have NOT tested this on Mojave, and APFS changes how disks are partitioned, so I don't know if this will work for APFS volumes or not. YMMV!
I take no credit for this, but I forgot who the source was:
#!/bin/sh
recoveryHDPresent=`/usr/sbin/diskutil list | grep "Recovery HD" | grep disk0`
if [ "$recoveryHDPresent" != "" ]; then
#Mount Recovery HD
recoveryPart=$(diskutil list "Recovery HD" | grep Apple_Boot | rev | cut -d " " -f 1 | rev)
diskutil mount $recoveryPart
#Get OS version
echo "<result>$(/usr/bin/defaults read /Volumes/Recovery HD/com.apple.recovery.boot/SystemVersion.plist ProductVersion)</result>"
#Unmount RecoveryHD
diskutil unmount /Volumes/Recovery HD
else
echo "<result>No Recovery HD present</result>"
fiOnce you have that, you can run logic on it.
Alternatively, you can do the whole comparison in the EA like this:
#!/bin/sh
recoveryHDPresent=`/usr/sbin/diskutil list | grep "Recovery HD" | grep disk0`
if [ "$recoveryHDPresent" != "" ]; then
#Mount Recovery HD
recoveryPart=$(diskutil list "Recovery HD" | grep Apple_Boot | rev | cut -d " " -f 1 | rev)
diskutil mount $recoveryPart
#Get OS version
recoveryHDVer=$(/usr/bin/defaults read /Volumes/Recovery HD/com.apple.recovery.boot/SystemVersion.plist ProductVersion)
systemVer=$(sw_vers -productVersion)
if [ $recoveryHDVer != $systemVer ]; then
echo "<result>Mismatch</result>"
else
echo "<result>Match</result>"
fi
#Unmount RecoveryHD
diskutil unmount /Volumes/Recovery HD
fiHope that helps!

+3I had something similar a while back that i have recently revisited.
Think my original base commands must have been the same as @JayDuff but i ran into many issues over the months and it's now morphed into something of a monster, but it does seem to cater for every scenario i can think of.
You can find the latest version HERE
But at time of posting, this is the current code I am using.

#
# - 14/10/2018 - V1.0 - Created by Headbolt

# - 01/04/2019 - V1.1 - Updated by Headbolt
# Updated for Mojave
# - 03/11/2019 - V1.2 - Updated by Headbolt
# Updated for Catalina and later by checking for the
# crossover points rather than individual OS Versions
# - 04/11/2019 - V1.3 - Updated by Headbolt
# Updated Again to Cycle through all instances of Recovery Partitions
# and report the Highest Version Number as what is available
# - 05/11/2019 - V1.4 - Updated by Headbolt
# Updated Again to remove Version based Disk Number and instead allow setting
# a variable to specify a number of disks to check and cycle through them all.
# this was to accomodate varying configurations of Hardware etc
