Hi Bhargav3. Thank you for this fix. I am not exactly sure what you mean in step 3 and 4. Specifically how to find these things and change them. Where do I run that command? Terminal, in the preferences somewhere? Apologies, just a newbie to using Python with Arduino on a Mac. I was able to use it on a Windows PC last year, but this is a different animal and things change in a year. If you know of a video, or made one yourself, of how to do this, I'm a visual learner. Thank you very much for taking the time to read this and any help you can give!
