Hi electricRGB and welcome to the forums!

I have been testing BIAB 2021 on macOS Monterey for a while and I haven't experienced the issue you're having. I'm using an M1 Macbook Air - theoretically the M1 Max shouldn't operate that differently than the M1, but as we haven't tested on an M1 Max yet we don't know for certain. I've made a report to the developers so they can look into this at least.

For now try installing the latest build update and see if that helps: https://dl11.pgmusic.com/support/mpatch/bb2021_mac_update_build515.pkg

If that doesn't help, please try the following:

Download the txt file attached to this reply onto your desktop - please make sure it is not renamed, it should be named "WriteBootupLog.txt"
Open a Finder window then navigate to /Applications/Band-in-a-Box/Data
Copy or move the WriteBootupLog.txt file into the Data folder
Try running BIAB again.
If BIAB does not open after a couple minutes, please look in the Data folder for a file named "BootupLog.txt", copy it to your desktop, then either attach it to your reply here or email it to us at support@pgmusic.com so we can take a look.
