Could you be a little more descriptive, please? I take it you’re using Big Sur.
What are the symptoms you are observing?
Are there any alerts or dialog boxes that appear when you try to launch the BeatBuddy Manager (BBM)?
The ARM processor may be the cause of the problem but I’m thinking that if the BeatBuddy Manager (BBM) worked under Big Sur on an Intel-based Mac, it should work on your M1. You can search the forum for Big Sur to see if that will help. Take a look at my post 13/21 BB Manager compatibility with Big Sur
It could be that the BBM will not run natively on the M1 or under the Rosetta v2 emulator. Here’s a list you can check for software and apps compatibility https://isapplesiliconready.com
Let us know if you can get it working or not. If not, it’s something that the developers will have to fix in the “one of these days” release of the new and improved BBM.
