Description of issue

Installed brew on a new Mac Studio.

brew install faust seems fine, but...

when I try to run a script which calls Faust it fails silently in terminal. Console shows

default    14:31:14.972368+0100    kernel    AMFI: '/opt/homebrew/Cellar/faust/2.72.14_1/bin/faust' is adhoc signed.

This seems like a brew problem rather than a faust one, so querying here. Any suggestions?

Did you migrate this from another Mac?

[muellmusik]

No, fresh install.

What happens when you run brew test faust?
