Sometimes the macOS version is written in different ways in multiple places on the file system. It's not (necessarily) consistent. In smart groups, this can be a little frustrating I suppose, but, just know this & have a way of handling it...
Here is one way (certainly not the only way) to deal with this in a script:
macosx="$(/usr/bin/sw_vers -productVersion | /usr/bin/awk -F '.' '{print $2}')"
macos11="$(/usr/bin/sw_vers -productVersion | /usr/bin/awk -F '.' '{print $1}')"
if [ "$macosx" -gt 15 ] || [ "$macos11" = 11 ]
then
do something here...
fi
This would account for if the version comparison uses 11 as the 1st number, or something greater than 15 (like 16...) as the 2nd number. Enjoy!
