I installed the BIAB app on my Mac, then copied my Real Tracks and Drums onto an external drive. Disconnect the hard drive.

Now, when you first open the app, you will need to point to the directories that contain Real Tracks and Drums. Watch the videos on this first.

If you don't do this immediately, there can be an issue with finding it later. I know the workaround but not for Catalina.
