New Aeneas Installer with Python 3.9 on Mac hangs

[chrisvire]

Both me (on Apple Silicon) and another user (on Intel) tried the new Aeneas Install with Python 3.9 on Mac. When we try to use it within SAB, the aeneas_task hangs and never completes. I even tried running the generated sync-audio.sh (in App Builder/Scripture Apps/Phrases/) from the terminal.
