I downloaded a program called "Clean My Mac" . I got rid of things that were unused. I don't know why this happened except I wasn't thinking but now all languages are gone (didn't think at the time that would be an issue) but...I have a son taking Greek and I had to print out a test for him. I didn't notice it but it did not print out in Greek. How do I get back languages without having to re-install the OS?
