I'm currently running BIAB 2020 (426) Audiophile on a mac os 11.6. My DAW is GarageBand 10.4.5. The brick wall I always ran into with BIAB was their DAW plugin not interfacing with GB. The problem was the plugin always freezes when choosing a style. It's message is "Initializing Band-In-A-Box Engine". This issue has PG's customer support stumped.

PG music customer service announced "no more bug fixes for 2020" so I am pinning my hopes on getting the BIAB DAW plugin to work with a BIAB 2021 upgrade. According to customer support they are not aware of any problems with their 2021 DAW plugin and GB.

My two questions are: Will investing in a 2021 BIAB upgrade fix the issue with the BIAB DAW plugin?
and secondly, does any one know how well BIAB 2021 interfaces with OS Monterey if I were to upgrade my operating system as well?
