From MA 5.6.6 and later, the URL-based download McAfeeSmartInstall.app file changed to McAfeeSmartInstall.sh. It’s a shell script file that bundles the app and configuration data. After the file is downloaded, the user can modify the McAfeeSmartInstall.sh script through a vi editor.

IMPORTANT: You can modify a script line. But, don’t add any new lines because the data is packaged at the end of the scripts.

Change the content of the McAfeeSmartInstall.sh file:

1. Edit the McAfeeSmartInstall.sh file using a vi editor.
2. Change line 45 and 46, and set the Absolute path instead of the symbolic link:
   
   From:
   sudo cp -f $temp_directory/coninfo.xml /tmp/coninfo.xml
   open -W -a "$temp_directory/$APP_FILE_NAME" --args -c "/tmp/coninfo.xml" "$@"
   
   To:
   sudo cp -f $temp_directory/coninfo.xml /private/tmp/coninfo.xml
   "$temp_directory/$APP_FILE_NAME/Contents/MacOS/McAfeeSmartInstall" -c "/private/tmp/coninfo.xml" -s -g
   
   IMPORTANT: 
   • Make sure the edit changes only lines 45 and 46. There must not be a line 47 with any new data.
   • The file /tmp/coninfo.xml is an alias name of /private/tmp/coninfo.xml.
   • Make sure you allow the shell script to write to /private/tmp.
      
3. Save the file and rerun the installation on the Mac. You’re no longer prompted for a user password.
   
   NOTES:
   • The script must be executed with sudo.
   • For assistance with sudo, see KB52707 - McAfee Agent command-line switches.
