I don't know why your file name starts with "User:". I don't think that
works on a Mac.

Try
import("/Users/paolopuggioni/Desktop/miocubo.stl”);

You are not showing the entire script, only a single line of the script.
This line by itself does not produce a parser error. The syntax error is on
line 3, so the script must have at least 3 lines.

If you’re unsure about the syntax of how to load a specific STL file into OpenSCAD, drag and drop the STL file onto the OpenSCAD program.
OpenSCAD will create a new window whose sole content is the STL import statement. You can then copy and paste that line into your own program.
e.g.:

import("/Users/me/Downloads/epoxy_spatula.stl”);

Looking at some of the samples you’ve provided I would note that

1. There should be no colon “:” after “User”
   import(“User:/my name/Desktop/miocubo.stl”);
   should be:
   import(“User/myname/Desktop/miocubo.stl”);

2)It looks like you’re adding spaces in the path, where there should be none
import ( "/ Users / paolopuggioni / Desktop / miocubo.stl”);
should be:
import ( "/Users/paolopuggioni/Desktop/miocubo.stl");

STL files are NOT scripts... they are static objects... so you can’t revise them directly
