First, I do not publish my application to the AppStore, but I need to customize a sandbox environment. It seems that sandbox-exec cannot configure entitlements, so I have used some other APIs, such as sandbox_compile_entitlements and sandbox_apply_container. When encountering the entitlement "com.apple.security.files.user-selected.read-only", I am unsure how to correctly write sandbox profile to implement this. Can anyone help me?
