Good afternoon,  
I have problems to run Processing at a MacOs system with Catalina.  
The program returns errors when you send simple sentences as  
print(“Hello World!”);  
It returns syntax errors.  
¿Do you know why occurs this error?.  
Many thanks in advance

@sacrisenka  
What are the syntax errors?
