The MUT or Mass Update Tool is an unofficial tool which is not affiliated with Jamf. It is a GUI tool designed to simplify making mass updates to your Jamf Pro Server, whether cloud hosted or on premises. Admins can use a CSV file with a unique identifier in column A (either serial number or Jamf Pro ID), and an attribute to be updated in column B, and update most attributes for either Mobile Devices or Computers in their Jamf Pro Server.
