macOS Installations: Running the License Initialization Script

As part of the Standalone installation of Thermo‑Calc, the Setup runs a license initialization script. If this part of the installation process did not complete properly for a standalone installation, you must manually run the license initialization script. You need the administrator username and password for these steps.

For this script to successfully initialize the license, the license file must be called lservrc and be located in the folder:

/Users/Shared/Thermo‑Calc

Installation Default Directory: macOS

  1. Open a terminal window. The Terminal application is in the /Applications/Utilities folder.
  2. At the prompt, enter this command:

    $ sudo /Applications/Thermo‑Calc-2025b.app/Contents/Resources/license-initialization-macOS-x86_64.sh

    If you are not already logged in as an administrator, you probably cannot run the sudo command. If this is the case, then you can use the su command in the terminal window to login as an administrator. Contact your local system administrator for help.

  3. Enter the administrator password and press Enter.
  4. When you restart your computer and run the license initialization script, you are ready to start using Thermo‑Calc.

    If you did not install a license file during this procedure, you can still start Thermo‑Calc although you will get the No license file found message.
