So this issue appears to be the result of the new macOS 11.1 and since the current stable release of the Processing IDE for the Mac is 10.13 - those who have or plan to acquire a new Apple product that will use the OS 11.1 - may encounter this issue and hopefully a fix will appear in the 4.0 version of Processing is released.
