Audio in problem with Mac OS Catalina

I’ve found a workaround that was suggested by another person on the forum:

It involves: opening the Processing 3 app through Terminal by typing:
/Applications/Processing.app/Contents/MacOS/Processing;
Then opening the file needing mic access - this triggers the pop-up asking to access camera and mic and then it works…
Hopefully there will be a simpler solution in the future…but this works for now. See the github post where this was mentioned:
