Script worked great, they just finally finished the released the rebrand to trellix. Might want to update the minor changes to file paths. Thanks again.

Feel free to fork the script and update it for the current version. I'm no longer working with the McAfee/Trellix tools, and @scheb posted a farewell notice on the MacAdmins Slack #mcafee channel in March, so it's unlikely of either of us will be making further updates.
