My sandboxed AUv3 cannot access user samples files

Hello
I store in my plugin path to the user selected sample from HDD. The sample loads fine when drag n dropped but recall and reload from preset (in Logic Pro) or project is causing “operation not permitted” error. How to solve that? Setting full disk access for Logic or my AU3 App (cannot set it for appex) does not work.

Have you read Apples documentation how to program in a sandboxed environment. There you should find everything you need to know.

I just adopted the AUv3 wrapper from example.

For file access you need to make sure to follow Apple’s guidelines for sandboxed apps.

I will take a look. Thank you
