I've recently been replacing our drives with SSD in older MacBooks and MacBook Pros and have started using a scripted version of enabling trim support if there is an ssd installed, however I wanted to make an extension attribute to check that it is acutally enabled. Any ideas?

#!/bin/bash



TrimCheck=`system_profiler -detailLevel Mini SPSerialATADataType | grep -w TRIM | awk '{print $3;}'`



if [[ ! $TrimCheck ]]; then

  echo "No Device supporting TRIM found."

  echo "<result>Not Applicable</result>"

elif [[ $TrimCheck == "Yes" ]]; then

  echo "Device found and TRIM is Enabled."

  echo "<result>Enabled</result>"

elif [[ $TrimCheck == "No" ]]; then

  echo "Device found and TRIM is Disabled."

  echo "<result>Disabled</result>"

else

  echo "Error"

  echo "<result>Error</result>"
