Cannot access portal after Community Ed Install on MacOS


I installed the latest version of the community edition of Bonita Studio on MacOS.
I can run the application but when I am trying to access the portal the URL http://localhost:8080/bonita/loginservice?username=walter.bates&password... is not found.
Same with http://localhost:8080/bonita/
Safari says that the server cannot be found.
I am not clear if this is an installation problem. I don't understand if the installer includes all the dependencies or if I need to install JRE and Tomcat separately. Or it may be a security issue.

Your help would be welcome.
