Before You Begin

These steps assume you have downloaded NNM and are running all programs as a root user or with equivalent privileges.


  1. Double-click the .dmg file downloaded from the Tenable Downloads page to mount the disk image NNM Install. The specific filename varies depending on your version.

  2. Double-click the Install NNM.pkg file.

    The Install Tenable NNM window appears, which walks you through the installation process and any required configuration steps.

  3. Click the Continue button.

    The Software License Agreement screen appears.

  4. Agree to the terms to continue the installation process and use NNM.

    Tip: You can copy the text of the agreement into a separate document for reference, or you can click the Print button to print the agreement directly from this screen.

  5. Click Install to begin the installation.

    A window appears asking for authentication permission to install the software.

  6. Click the Install Software button.

    A window appears, requesting permission to allow NNM to accept incoming network connections. If this option is denied, NNM is installed but functionality is severely reduced.
