This version of Tecplot does not require a product key. Continue through the dialog boxes when a product key is requested, accepting the default options.

When launching Tecplot RS, you may receive a dialog that says “The RSvariables.txt file was not found. Without it, the system will use a set of built-in defaults.” This is normal behavior. 


  1. Download and launch the Tecplot 360 installer for macOS.
  2. Drag the included Tecplot folder to the Applications folder.
  3. You can now launch the software from its folder within Applications, or by finding it in Launchpad or Spotlight.
  4. At the licensing dialog, select Network license server.
    License server name:
    Port number: 5053

If you receive a License Manager Host dialog box, select Launch Tecplot. If you do not want to view this dialog box each time you launch Tecplot, uncheck the Always Show this Dialog checkbox and click on the Launch Tecplot button.
