[BUG] macOS standalone: Warn users with models not in Music/ directory #281
Description
After #242, the standalone on macOS will be unable to load models that do not live in a directory with entitlements.
Two possibilities:
- Alert the user to move their models.
- Implement a fallbak the only requires the entitlements for the single (which have been given), and disable the arrows. (May need a modal or else users will be confused anyways.)
Nothing needs to be done for macOS plugins (VST3, AU) nor anything on Windows.
