# Custom command attribute to look up and report a Mac's marketing name
# MDMs including Mosyle use MDM commands to return a Mac's model identifier
# for inventory purposes, but Apple reuses model identifiers across model years.
# This CA checks Apple's support web service to retrieve the marketing name.
# Custom command attributes are intended for use with Mosyle MDM
#

## Get the Mac's serial number
serialNum=$(ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/IOPlatformSerialNumber/{print $4}')

## Check the length of the serial number and set an appropriate string to use for the lookup
if [[ ${#serialNum} -ge 12 ]]; then
    Serial=$(echo "$serialNum" | tail -c 5)
else
    Serial=$(echo "$serialNum" | tail -c 4)

## Get the full model name from Apple's support page, using the portion of the Serial Number

## If we didn't get an empty response, echo the full model name
if [ "$fullModelName" != "" ]; then
    echo "$fullModelName"
    ## Echo the result for the EA
