Really not liking what I am seeing with macOS 15.1 and how it associates unsigned apps and packages as "untrustworthy and possibly full of malware".

Did an example with a simple audio plugin package, steps are:
1. Try to open the pkg and have it fail, **do not press "Move to Bin"**
2. Open System Settings, go to security and press "Open Anyway"
3. Click again "Open Anyway" in the new dialog
4. Input password

All this while screen is screaming "UNSAFE!" at you.
