/**
 * Ensure you have a ~/Library/Desktop/Wallpaper.jpg file ready to go.
 *
 * The script requires sudo access, and assumes you have TouchID connected
 * to `sudo` by prepending:
 * ```
 * auth       sufficient     pam_tid.so
 * ```
 * to the `/etc/pam.d/sudo` file.
 *
 * So your file should look like:
 * ```
 * # sudo: auth account password session
 * auth       sufficient     pam_tid.so  # <-- Add this line to top
 * auth       sufficient     pam_smartcard.so
 * auth       required       pam_opendirectory.so
 * account    required       pam_permit.so
 * password   required       pam_deny.so
 * session    required       pam_permit.so
 * ```
 *
 * Notes:
 *  - This will be reset each time macOS is updated.
 *  - If you have using DisplayLink, TouchID will not work, but macOS
 *    will prompt you for your password.
