Mac EPERM: operation not permitted

Starting with the release of macOS 10.15 Catalina, Apple has introduced a new security feature that ensures that 3rd-party applications are manually granted access to the user's file.  Hackolade stores settings and logs in your Documents folder, and it cannot operate without it.  So, if prompted with this dialog, you must click OK.

To avoid the error "EPERM: operation not permitted", you must grant access to the application as described above.
