exernalDragAndDrop works to daw, but not to finder window, on mac

I have an issue where on mac I am calling performExternalDragDropOfFiles in order to allow users to drag audio files out of the application, and for some reason it is allowing users to drag the files into their Daw, but not to any other finder windows

Some important notes

  • This is in a dynlib, which is signed
  • The containing application is also signed and notarized
  • Both the dynlib and containing app contain all the “file read/write” entitlements we can find

I’ve been scratching my head for a while on this, but its a huge issue.

Any advice?
