Posted asking how to. Found the answer.
This is what I've come up with to use Regex to sort out hardware that supports Mojave.
I used the Model Identifier



MacBook - ^MacBook(?![1234567],[1-9])[0-9]{1,2},[1-9]
MacBookAir - ^MacBookAir(?![1234],[1-9])[0-9]{1,2},[1-9]
MacBookPro - ^MacBookPro(?![12345678],[1-9])[0-9]{1,2},[1-9]
Macmini - ^Macmini(?![12345],[1-9])[0-9]{1,2},[1-9]
iMac - ^iMac(?![1-9],[1-9]|[0-2]{2},[1-9])[0-9]{1,2},[1-9]
iMacPro - ^iMacPro[0-9]{1,2},[1-9]
MacPro - ^MacPro(?![1234],[1-9])[0-9]{1,2},[1-9]



The only issue I see is the MacPro 5,1 must have a Metal GPU. Would I have to create an EA to pull what video card are in those boxes?

FWIW, a once-per-computer policy to determine if computer supports Mojave:



#!/bin/bash



outputFile="/tmp/.tempMojaveTestFile.txt"

modelIdentifier=$( sysctl -n hw.model )

folderPath="/Library/COMPANY/SearchResults"



cat << 'EOF' > $outputFile

iMac10,1

iMac11,1

iMac11,2

iMac11,3

iMac12,1

iMac12,2

iMac4,1

iMac4,2

iMac5,1

iMac5,2

iMac6,1

iMac7,1

iMac8,1

iMac9,1

MacBook1,1

MacBook2,1

MacBook3,1

MacBook4,1

MacBook5,1

MacBook5,2

MacBook6,1

MacBook7,1

MacBookAir1,1

MacBookAir2,1

MacBookAir3,1

MacBookAir4,1

MacBookAir4,2

MacBookPro1,1

MacBookPro1,2

MacBookPro2,1

MacBookPro2,2

MacBookPro3,1

MacBookPro4,1

MacBookPro5,1

MacBookPro5,2

MacBookPro5,3

MacBookPro5,4

MacBookPro5,5

MacBookPro6,1

MacBookPro6,2

MacBookPro7,1

MacBookPro8,1

MacBookPro8,2

MacBookPro8,3

Macmini1,1

Macmini2,1

Macmini3,1

Macmini4,1

Macmini5,1

Macmini5,2

Macmini5,3

MacPro1,1

MacPro2,1

MacPro3,1

MacPro4,1

Xserve1,1

Xserve2,1

Xserve3,1

EOF



if [[ -e "$outputFile" ]]

then

    if grep -R "$modelIdentifier" "$outputFile"

    then

        touch "$folderPath"/SupportsMojaveNOT.txt

    else

        touch "$folderPath"/SupportsMojave.txt

    fi

else

    echo "$outputFile does not exist."

    exit 1

fi



rm "$outputFile"



exit 0


Would then need a simple EA to show which file exists, to feed a Smart Computer Group.

You can use the script posted at https://github.com/laurentpertois/Mojave-Compatibility-Checker to return a true or false value in an Extension Attribute.
