2. On a Mac, open the terminal and type “sudo nano /etc/paths”.
3. On Windows, click on the “Environment Variables” button, then in the “System Variables” section, find the “Path” variable, double-click to edit it, and add the path to the “bin” folder of Tomcat at the end of the variable value.
4. Navigate using the arrow keys in the terminal on Mac to the open file, add the path to the “bin” folder of Tomcat at the end of the file, and then save and exit by pressing Ctrl + X.
